    "Developed by world-renowned surgeon Ronald F. DeMeo, MD, Demron® was originally created to protect medical personnel and patients from the harmful effects of X-ray radiation in the operating room. “I’ve worked around radiation my entire career, and I have seen what it can do to the human body, even at low levels. Demron® was my way to better protect myself in the O.R., and bring something better to the people who work around radiation every day.” Dr. DeMeo developed Demron® as a way to finally shed light on the archaic field of radiation protection. “Until now, we’ve simply ignored the threat of radiation because there was nothing that could be done. Lead has been the standard for over 50 years; a toxic, heavy, impractical standard to say the least.”

  • VOX POPULI: Just a little bit of nuclear annihilation is a mad idea

    "Making smaller nuclear weapons to create a greater deterrence is a preposterous idea.

    "Tatsuichiro Akizuki, a doctor who survived the atomic bombing of Nagasaki, has just penned his thoughts after watching the initial screening of a documentary depicting the nuclear destruction of that city and Hiroshima in 1945.

    "The film shows a desolate landscape with heaps of charred roof tiles lying amid the ruined city.
    But some viewers have complained that scenes showing humans are scarce.

    “'You can't describe the atomic-bombed Nagasaki or Hiroshima without human victims,' one said.

    "Later, scenes of survivors receiving medical treatment were added, but Akizuki was not happy with the result. There were images of patients with burns covering their entire bodies and also people with horrific wounds.
    In the aftermath of the atomic bombing, however, “the earth and rivers were filled with throngs of such people,” Akizuki wrote.
    There were certain aspects of the devastation that could not be described in the film.

    "More then 70 years since the atomic bombs were dropped on the cities, there are still huge arsenals of nuclear weapons in the world and something called a 'nuclear strategy' is being developed. The U.S. administration of President Donald Trump recently unveiled nuclear policy guidelines for the next five to 10 years….[cont.]

    • [cont.]
      "The new U.S. nuclear strategy calls for developing smaller nuclear weapons in that their use will be more acceptable. The idea being that if they are "easier to use" it enhances the U.S. nuclear deterrent.
      Some news reports have said these smaller nukes would have a quarter of the destructive power of the bomb that devastated Nagasaki.
      "The military logic of considering such nuclear arms as “easier to use” is simply shocking.

      "Former U.S. Secretary of State Colin Powell once rejected this kind of thinking.

      “'No sane leader would ever want to cross that line to using nuclear weapons,' Powell said in an interview with The Asahi Shimbun about five years ago. 'And, if you are not going to cross that line, then these things are basically useless.'…”

      Hi Plowboy, there was also some discussion here in 2013-20154 when there were plans to pull spent fuel out of the Reactor 4 SFP. If memory serves, it has high tensile strength and stands up well to radiation. It could hypothetically (theoretically?) be used for radiation shielding.

      However, it's very expensive to produce, and producing the huge amounts needed for a project like Fukushima Daichi or Chernobyl would likely be cost-prohibitive.

      My research showed it's typically produced in 3 foot or 1 metre/meter square sections (small).

      Too bad, the stuff would probably be suitable to use as some kind of liner around the leaking bottoms of the reactors, on top of the burned out reactor buildings, etc.

      I think they should consider developing some kind of borosilicate spray ceramic to use. It may be possible to create something like that which may withstand the Wigner Effect produced by the high radiation. And the graphene might help mitigate the negative and degradative Wigner Effect on fatiguing, aging reactor metals and structures.

      Not sure if it prevents gamma shine.

      We haven't seen discussion of the gamma shine issue at the tank farm for awhile. I think Arnie Gunderson was the one who brought attention to that. Another big problem for the workers there.

      Now if there were only a way to keep the uranyl-peroxide buckyballs from forming and circulating around….

    Check this out. Just happened to see it. Radiation resistant soil microbes. We should probably be focusing a lot of research efforts here. If we are going to have GMO’s, maybe this is where we should be doing it.
    Never thought I’d say that, but it may be a matter of survival. We might have to re-program our genes for radiation resistance. You know I’m not keen on playing God though…. Note the Hanford and Savannah River sites are mentioned, as well as thermophilic organisms surviving in geothermal vents.

    From "Applied and Environmental Microbiology"

    Extensive Diversity of Ionizing-Radiation-Resistant Bacteria Recovered from Sonoran Desert Soil and Description of Nine New Species of the Genus Deinococcus Obtained from a Single Soil Sample

    "Ionizing-radiation-resistant organisms have been isolated from a wide range of environments, including sawdust , sewage, paper mill machinery, animal feeds, processed meat, dried food, feather pillows, room dust, textiles, irradiated meat and fish, high-level nuclear waste sites at Savannah River in South Carolina and at Hanford in Washington, thermally polluted water, and irradiated rice. Other environments from which radiation-resistant isolates have been obtained include soil, feces, warm freshwater geothermal springs, and shallow and abyssal marine thermal springs." (cont.)

      "A number of A. radioresistens strains have also been isolated from clinical sources. Many of the environments from which ionizing-radiation-resistant organisms have been isolated can be considered to be dry or desiccated, and it has been shown that many of these strains are also desiccation resistant…"

      (This preceded the info. above.)

      "Extreme ionizing-radiation resistance has been observed in several members of the domains Bacteria and Archaea. Of the genera containing ionizing-radiation-resistant organisms, Deinococcus and Rubrobacter show the highest levels of resistance, and all species of these genera have been shown to be either gamma radiation resistant or UV radiation resistant or both. The genus Deinococcus, which represents a deeply branching lineage within the Bacteria, comprises 11 validly described species, D. frigens, D. geothermalis, D. grandis, D. indicus, D. marmoris, D. murrayi, D. proteolyticus, D. radiodurans, D. radiophilus, D. radiopugnans, and D. saxicola.

        HT NOTE: THESE ADAPTATIONS CANNOT BE EXPLAINED AS ADAPTATION TO NATURAL BACKGROUND RADIATION. The conclusion is inescapable: at least some of the organisms have adapted in response to MAN-MADE RADIATON. Which should tell us something important (and give us some pause to hope life will go on despite our messing everything up!)

        "…exposure to doses greater than 25 kGy , while species of the genus Chroococcidiopsis survive exposure to 15 kGy. Strains of the species Acinetobacter radioresistens, Hymenobacter actinosclerus, Kineococcus radiotolerans, Methylobacterium radiotolerans, Pyrococcus furiosus, Pyrococcus abyssi, Thermococcus gammatolerans, Thermococcus marinus, and Thermococcus radiotolerans are less resistant and have been shown to survive after exposure to much lower levels of radiation.

        The origin of ionizing-radiation resistance in these prokaryotes is obscure, and this resistance cannot be explained as an adaptation to environmental radiation. Natural sources of ionizing radiation on Earth emit at very low levels (35, 64), making it impossible to generate the acute doses to which these organisms show resistance. It has been suggested that DNA repair mechanisms may have evolved not to counter the damage of ionizing radiation but rather to compensate for desiccation, another naturally occurring stress that generates a pattern of DNA damage similar to that produced by ionizing radiation…."

        • HoTaters HoTaters

          OOPS! Drew the WRONG CONCLUSION. Dessication produces adapation which may enable these organisms to survive what might otherwise be lethal or harmful (DNA damaging) levels of man-made radiation. (I knew I was probably being too optimistic!) Nonetheless, this study is great for documenting adaptations that should give us hope life may go on here (despite us or maybe even with us if we haven't blown it too badly.)

          "The process of desiccation is inherently DNA damaging and results in DNA double-strand breaks, the primary lethal lesions resulting from exposure to ionizing radiation, and it is assumed that desiccation-tolerant species, as well as ionizing-radiation-resistant species, can avoid or effectively repair these lesions."

    “It was complete chaos" says Hanford worker who inhaled plutonium

    The worker tested positive for inhalation of the potential lethal nuclear isotope of plutonium – a key ingredient to the production of nuclear bombs and warheads.

    Author: Susannah Frame
    Published: 5:25 PM PST February 13, 2018

    The plutonium spread also made it onto cars. The KING 5 Investigators have found 36 cars total. Seven of them were personal vehicles, driven off the site by unsuspecting employees. The vehicles, with contamination on them, were driven into town and to their homes. One of those cars belongs to the worker who was contaminated internally six months earlier.

    “We got in our cars and went home to our families. We hugged our wives, our children, our grandchildren and did our daily routines, so we don’t know what we took anywhere,” said the worker.

    On January 9, the Department of Ecology and the EPA sent a joint letter to U.S Department of Energy officials to communicate their great concern. For the first time in Hanford’s history, the regulators enacted a provision allowing them to halt work on a project due to a “creation of danger” to people and the environment.

    Several Hanford workers said the PFP supervisors have been rushing the job for months in order to meet deadlines. That led to sloppy work and shortcuts taken, they said.

    Nuke News…

    Research into low dose radiation – a very complex issue

    With bipartisan support, the US House Science, Space, and Technology Committee recently passed a bill to revitalize low-dose radiation research. The bill, which would authorize an estimated $96 million in funding, has also garnered support from researchers and groups with opposing views on the seriousness of effects of ionizing radiation in the low-dose region, defined as being below 100 millisieverts—roughly the amount of radiation from 10 CT scans.

    Studies of excess cancers among survivors of the Hiroshima and Nagasaki bombings have estimated a 1 percent increase in long-term cancer risk for adults receiving a dose of 100 millisieverts (the risk is higher for children), with the risk below that level declining in proportion to the dose. However, stakeholders and researchers with different hypotheses continue to debate whether or not downward extrapolation by dose magnitude—the “linear no-threshold” model deemed most reasonable by a National Research Council committee of experts—is the best way to estimate risk. ……

    • Jebus Jebus

      The hope of many supporters of the proposed legislation, voiced by Rep. Roger Marshall, a Kansas Republican, is that it may assist “the development of nuclear energy opportunities,” in part by reducing the size of nuclear plant evacuation zones. The bill’s supporters presume that the finding of a threshold or hormesis region would demonstrate that the existing linear no-threshold model is an over-protection that, as Northwestern University radiation biologist Gayle E. Woloschak wrote in a letter of support for the bill, “may be wastefully expensive and deplete funds that could be used for other strategic goals for the nation.”

      Past research by the Energy Department to upend the linear model has failed to fulfill that dream, finding health effects below 100 millisieverts from even protracted exposures. There is so much existing epidemiological data from exposed workers, patients receiving medical diagnostics, and residents living around the Soviet nuclear complex—as well as the Japanese atomic bombing survivors—that new research, whatever it shows, will need to be interpreted in the light of all the evidence.

    Hey, a segue

    Early effects of low doses of ionizing radiation on the fetal cerebral cortex in rats – 1990

    Pregnant rats were exposed to .gamma. radiation from a 137Cs irradiator on gestational Day 15. Fetuses that received 0.25, 0.5, 0.75, or 1.0 Gy were examined 24 h after irradiation for changes in the cells of the cerebral mantle of the developing brain. The extent of changes following 0.5 Gy was studied at 3, 6, 12, or 24 h after exposure. Cortical thickness of the cerebral mantle was not significantly altered. The number of pyknotic cells, number of macrophages, nuclear area, and number of mitotic cells were altered in a dose-related way. The number of pyknotic cells was significantly increased at all doses. A positive correlation between the number of pyknotic cells and the number of macrophages developed with time. At 3 h after irradiation about 60% of pyknotic cells were found in the subventricular zone and about 25% in the intermediate zone and cortical plate. The number of such cells in the upper layers of the cortex steadily increased up to 24 h, at which time about 70% of pyknotic cells were in these two layers. The relationship of the movement of pyknotic cells to migration of postmitotic neuroblasts is discussed.

      'Pyknosis, or karyopyknosis, is the irreversible condensation of chromatin in the nucleus of a cell undergoing necrosis or apoptosis. It is followed by karyorrhexis, or fragmentation of the nucleus. In embryonic life, the SubVentricularZone refers to a secondary proliferative zone containing neural progenitor cells, which divide to produce neurons in the process of neurogenesis.

    I witnessed nuclear tests 60 years ago – and I’m frightened about the dangers of today—and-i%27m-frightened-about-the-dangers-of-today

    After a few days repairing machinery, including a bulldozer, in temperatures of 35C, Mr Bosson and his comrades were handed white overalls — supposedly for protection — and told to gather near trucks at a point on the island.

    Aware there was to be a test but ignorant of the effects that would soon overwhelm the assembled soldiers, Mr Bosson sat with his back to the test site, 20 miles away.

    They were split into groups and assigned a lorry. Unbeknown to them, that was part of an emergency plan if the wind changed and pushed the bomb blast cloud towards their part of the island. The soldiers would then have had to jump into the trucks and be driven to the port to clamber on to boats.

    “By that time we knew what sort of bombs they were testing, but it did not seem to matter because we were so young and it was like an adventure,” said Mr Bosson.

    “We were told to cover our faces with our hands and then there was a countdown — 3, 2, 1…flash. The light lit up in your hands.

    “There were 107 seconds between the flash and the explosion, 20 miles away. We couldn’t see anything in the sky as it was pure white.

    Prof discusses lasting effects of Chernobyl

    Despite the concerns raised by the Chernobyl disaster, Brown emphasized, the health effects have not been sufficiently addressed. Over the past three decades, the rate of cancer and infant mortality have both risen. Despite these statistics, legislation has left many of these health concerns unaddressed.

    The Yale Environmental Humanities Initiative invited Brown to speak because the organization was “interested in the way she is thinking about history and memory and the contested record of health and ecological effects of Chernobyl,” said Paul Sabin, who coordinates the environmental initiative.

    “It is part of a larger conversation that we’re having about landscape and memory,” Sabin said.

      "The PVGS Unit 1 safety related electrical busses remained energized from normal offsite power during the event.

      The Unit 1 'B' [EDG] is currently removed from service for maintenance.

      Due to ongoing planned maintenance on NAN-X02, Startup Transformer 2, fast bus transfer for NAN-S02 (from NAN-S04) was blocked.

      This resulted in a loss of offsite power to NAN-S02 and NBN-S02.

      The offsite power grid is stable.

      Unit 1 is currently stable in Mode 3 with the reactor coolant system at normal operating temperature and pressure.

    "One of Indian Point’s two nuclear reactors automatically shut down early Friday when a generator failed, prompting an inquiry by the Nuclear Regulatory Commission.

    This is the second time in four months that Indian Point’s Unit 3 shut down after an issue with a generator on the non-nuclear side of the pressurized water reactor."

    DOE budget seeks money to close MOX

    The Department of Energy’s budget request for fiscal 2019 asks for money to close the Mixed Oxide Fuel Fabrication Facility and says the agency prefers the “dilute and dispose” method to dispose of 34 metric tons of weapons-grade plutonium.

    Combined, the 68 tons is enough to create about 17,000 nuclear warheads.

    DOE’s preferred alternative of dilute and dispose — also known as downblending — is a hands-on process that mixes plutonium with inert material. Plutonium is ground up in a “glove box” by hand with a mortar and pestle. A small amount is then placed inside a canister and shaken with inert materials. The canister is then shipped to the Waste Isolation Pilot Plant for permanent interment at the salt-mine facility in New Mexico.

    Safety Problems Again Delay China’s Sanmen Westinghouse AP1000 Nuclear Energy Project

    Nuclear energy proponents often cite the seeming ongoing support for nuclear energy in China and Russia when arguing that the western world is being left behind by its move away from the electricity generation modality. What they don’t tell you, though, is that the projects in question are in general running way behind schedule, and are repeatedly unnerving regulators due to the presence of unresolved “safety concerns.”

    “China was originally seen as the lifeline for the global nuclear sector, with the country keen to approve dozens of new reactor projects to ease its dependence on polluting coal-fired electricity…But the pace of planned nuclear construction in the country was scaled back in 2011 in the wake of the Fukushima disaster in Japan.”

    Elsewhere, the situation regarding nuclear energy project delays and cost-overruns is similar, with the technology seemingly not capable of supporting the grandiose claims often made by those hawking it to governments around the world.

    "Along with roll call votes this week, the House also passed the Low-Dose Radiation Research Act (H.R. 4675), to provide for a low-dose radiation basic research program; and the Nuclear Energy Research Infrastructure Act (H.R. 4378), to direct the Secretary of Energy to carry out the construction of a versatile reactor-based fast neutron source."

    Nuclear winter? Well, it was the Russians according to this: "A STARTLING new book claims the nightmare scenario of a nuclear winter sparked by atomic bombs was made up by Russian spies as part of a fake news plot to spread panic in the West.

    The publication, written by a former British government adviser, claims the Doomsday theory was actually a scare story dreamt up by the former head of the KGB to spark chaos in enemy lands during the Cold War."

    I wait, sunrise. The overgrown pass behind, I'm born.

    Oh wait, that's not what I mean. I meant to say, if you read that and take into some consideration facts about collusion and so on, that's british propaganda, not russian.

    • FaunaLord FaunaLord

      Yes yes, there is american and russian collusion too. But importantly, this is from the british media and government, the british public is so deep in debt, they can't even imagine. They're the most obedient slaves you can find, they have no spirit or will, government has to chain them, brainwash them and lead them to "greener" pastures. By that I mean, concrete. Enjoy your concrete.

    "This report is being made in accordance with 10 CFR 50.72(b)(3)(v)(D) for an event or condition that could have prevented fulfillment of a safety function needed to mitigate the consequences of an accident.

    While troubleshooting an issue with the Unit 1B Diesel Generator Oil Circulating pump, damage of a bus bar was identified at the breaker that supplies the Unit 1B Diesel Generator Auxiliaries.

    One of the loads fed from this breaker is the Division 3 DC Battery Charger.

    It has been determined that the degradation of the bus bar may have prevented the Division 3 DC Battery Charger from performing its function which could have prevented the High Pressure Core Spray System (HPCS) from performing its design safety function.

    Since HPCS is a single train safety system, it has been determined that this failure could potentially affect the safety function of this system, and is reportable as an 8 hour notification."

      "At 1014 [EST] hours on 2/16/18, with Unit 1 in Mode 1 at approximately 100 percent power, the reactor automatically tripped when the Reactor Trip Breakers opened during Train B Solid State Protection System (SSPS) testing.

      The trip was uncomplicated with all systems responding normally post-trip.

      Operations manually started the motor driven auxiliary feedwater

      The turbine driven auxiliary feedwater pump (TDCAP) auto-started on low steam generator level.

      A Feedwater Isolation occurred as designed due to the Reactor Trip and Lo Tave condition.

      Operations stabilized the plant. Decay heat is being removed by the condenser.

      Unit 2 is not affected.

      "Due to the Reactor Protection System actuation while critical, actuation of the TDCAP and motor driven auxiliary feedwater pumps along with the Feedwater Isolation, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B) and an 8 hour non-emergency notification per 10 CFR 50.72(b)(3)(iv)(A).

        "Unit 1 is stable in Mode 3 following an uncomplicated trip.

        Offsite power has been restored to non-safety related electrical busses.

        Troubleshooting continues to determine the cause of the event.

        "During performance of the alarm response procedure, it was identified that the seismic monitoring (SM) system had been in alarm since the reactor trip and was incapable of performing its emergency plan function.

        [ That's interesting. ]

        Pursuant to 10 CFR 50.72(b)(3)(xiii), this condition constitutes a major loss of emergency assessment capability.

        Compensatory measures have been implemented in accordance with PVNGS procedures to provide alternative methods for HU2.1 event classification with the SM system out of service.

        Maintenance is currently in progress to restore SM system functionality."
