    The Brief Wondrous Life (and Long Dangerous Half-Life) of Strontium-90

    July 06, 2013

    Strontium-90 – like cesium-137 and a catalog of other hazardous byproducts of nuclear fission – takes a long time to decay. The detritus of past detonations and other nuclear disasters will be quite literally with us – in our water and soil, in our tissue and bone – for generations. These radioactive isotopes have already been linked to significant suffering, disease and death. Their danger was acknowledged by the United States when JFK signed the 1963 Test Ban Treaty. Now would be a good time to acknowledge the perspicacity of that president, phase out today's largest contributors of atmospheric Sr-90 – nuclear reactors – and let the sun set on this toxic metal's life.

  • Jebus Jebus

    The main problem with strontium-90 comes from its chemical similarity to calcium, so that this isotope is incorporated into bone. As a consequence of the worldwide nuclear weapons testing programs, strontium-90 can readily be detected in the teeth of persons who were born after 1963. A direct relationship has been established between the amounts of incorporated strontium-90 and the likelihood of cancer, and this finally led to the termination of the atomic bomb tests.

    Did the Atom Bomb Test Fallout Cause Cancer? 12/23/2010 08:10 am ET Updated May 25, 2011

    Of the more than 100 radioactive chemicals in fallout, Sr-90 was the most feared. Chemically similar to calcium, it attaches to bone and teeth, where it attacks cells, causing cancer. It can penetrate into the bone marrow, where the red and white blood cells so important to the immune response are formed. In 1956, Presidential candidate Adlai Stevenson made a speech singling out the potency of Sr-90:

    Earlier this month, the first results of the RPHP health study were released in an article in the International Journal of Health Services. Baby teeth of St. Louis baby boomers who died of cancer by age 50 had more than double — 122 percent more — the Sr-90 concentration than did Boomers who are alive and healthy. This research, known as a case-control study, is the first evidence that bomb tests harmed Americans using actual levels of fallout in human bodies. It is not yet possible to estimate the number of cancer victims from fallout, but it appears that the CDC estimate of 15,000 deaths is too low.

      Studying health risks of radioactive emissions from both weapons and reactors has been a highly politicized issue, as the military and industries producing these chemicals are not eager to present findings of harm. However, the only way to truly reduce cancer rates is to understand causes and take preventive actions. Baby teeth, even those from half a century ago, hold the clues to one such cause.

    Strontium 90 from Nuclear Fallout, Power Plants & Waste: Low Birthweight Babies, Cancer, and Leukemia

    In New York state the low birthweight percentage rose by nearly 40 percent from 1945 to 1965, when there had been a corresponding many-fold increase in strontium-90 found in American baby teeth. The postwar low birthweight rise is best revealed by New York, for which data begin in 1945. The low birthweight percentages are perfectly correlated with the measured geometric rise and fall in strontium-90 in the bone of New York adults for the years 1955-70. [5]

    Canadas Land of Milk and Strontium 90

    We live on the Pacific Northwest coast of Canada. By many accounts, our area was particularly hard hit by the radioactive fallout that came directly over to us, in the jet stream, from the triple meltdown and hydrogen explosions at the nuclear power plant at Fukushima Daiichi, Japan, in March of 2011.

    In Seattle, it was reported that the air was so contaminated after the accident that people were breathing in five “hot” radioactive particles a day!

    The fallout was found to come down heavily in the rain that is so frequent in this rain forest we call home. Initially Simon Fraser University, in British Columbia, detected Iodine 131 in the rainwater on Burnaby Mountain They also found it in the seaweed on the shores of North Vancouver

    Eventually we learned that the Air Monitoring Stations on Vancouver Island had picked up Radioactive Iodine 131 at levels 300 times higher than normal background.

    A lab in Washington State found levels of radioactive xenon gas 40,000 times higher than normal levels.

    So we knew the fallout had reached us. And we knew that there were at least 200 other radioactive substances that came along with the fallout from the nuclear plant accident. What we didn’t know was the level of contamination.

    • Jebus Jebus

      We learned that in California the tuna, milk, pistachios, naval oranges, prunes, wild mushrooms, strawberries, seaweed, beef, kale and spinach had been shown to be contaminated with radioactivity. However, having watched the jet stream patterns, we saw that our area in south western British Columbia was often missed by the atmospheric airflow from Japan.

      After the initial study came out from Simon Fraser University, no more radioisotope studies were conducted by the researchers at that university So we set about trying to find out if anyone else was testing for radioactive fallout in Canada.

    CNS Global Incidents and Trafficking Database – April 2017

    Yet the threat remains undiminished: the revelation in early 2016 that Islamic State operatives were monitoring a Belgian nuclear power plant suggests that terrorists continue to explore ways to access nuclear and other radioactive materials or sites.

    As in previous years, almost half the incidents in the 2016 database would be suitable for use in a radiological dispersal device (RDD).

    Clearly, radioactive materials, perhaps even including nuclear materials, are still within the reach of malicious individuals or groups.

  • danger kitty danger kitty

    Seems I'm always late to the party. I've got a strontium story. Since I've been following this fine Forum I've learned a lot about nuclear radiation. I've been able to put together what I've learned with my family medical history. It explains a lot.
    I was born in the early 50s. First child. My mother had another pregnancy the next year, stillbirth. Then the next year my brother came along. Shortly after my brother's birth every spinal disc in my mother's lower spine DISINTEGRATED. Soft bone. 20 years later, the same thing happened to me. Much slower. In my entire spinal column, starting from the bottom, half my discs disintegrated and disappeared, the vertebrae fused together. The other half turned to stone. Very painful as it occurred, but now that it's done, not much pain. The danger I face now is in my neck. Last place to calcify, with a twist. There is a bone spur growing on one of my cervical vertebra. Sometimes it presses on my spinal cord with disastrous results.
    It's called ankylosing spondylitis. Just a name. The common knowledge about people with this condition is that if you step off the curb wrong,you can become a quadriplegic. You know what I do for a living, I climb tall trees with a single chainsaw, rain logs out of the sky. I choose to continue doing the work I love despite the risk. I choose that because I was born to do this work. Otherwise I would have no life. I'm careful, and I'm VERY good at what I do

    • danger kitty danger kitty

      In addition to the spinal issues there were a lot of other effects from the strontium et. all. As my first wife discovered and informed me, I have a very high palatal arch. I was just a millimeter away from being born with a cleft palate. And I recall there was a lot of that in my classmates in elementary school. And a lot of worse things too.
      So, I was exposed to strontium at conception. In addition to my spinal problems, by the age of 15 my teeth started to disintegrate. And of course, the common practice of the time was to fill those cavities with mercury. By the time I was 20 I was in what appeared to be full-blown AIDS. Only problem is AIDS wasn't around then. Chronic fatigue progressively worsening,severe weight loss. I tried every kind of alternative health remedy to fix it. The doctors were no use.
      So Mercury in my strontium saturated teeth was killing me. It took 20 years to figure it out. When I found out that 'silver, fillings were actually 50% Mercury, 30% silver, I said damn, that's the problem. I had them removed after much struggle with the dentist, against doctor's advice and in 30 days I regained 40 lbs back. I'm 6 feet tall and I was a skeletal 95 lbs. I also got my energy back, normal levels.
      So then, I had a good twenty years, and then along came Fukushima. First strontium, then Mercury, then Fukushima. I won't even bore you with the lead and arsenic in occupational exposures. And you all know about the sky frackers. Been heavy here.
      What a…

      • danger kitty danger kitty

        During the mercury decades, the alternative medicine remedies I was trying did help a lot.Sometimes I was feeling pretty good, until i stopped using them. It kept me alive until I found the knowledge to remedy the problem. It kept me alive.

        Training for the Fukushima years…

            Danger Kitty, thanks for relating your story.

            The body is affected by poisons. But tracing the cause is very difficult. The majority arent aware of this and think everything is just due to bad luck

            Its bad luck alright

            • danger kitty danger kitty

              Yeah, the majority think it's just bad luck. It blows my mind to walk around knowing that all the medical horror stories of people I knew growing up where most likely, like my family, tremendously affected by fallout from the hundreds of bomb test in the 50s, 60s, etc, ad nauseam.
              It wasn't really any rocket science to figure out the strontium connection in my family. Bone seeker. Not when I've spent the last 5 years absorbing all the good information presented here at ene.
              I've noticed the 'bad luck' seems to be getting worse. I Q's don't seem to be faring very well…

          • q q

            Dunno wanna get too OT with this and sorry to hear. I kinda have to ask though, do you reckon fluoride could've played a part in your calcification?

            • danger kitty danger kitty

              Hi q. The munincipality of my youth didn't jump into the pile of fluoride stupid until a few years ago. By then I was long gone; for the past 44 years I've lived in a place where my water source is a well. Good water. No frackers in sight.

            • danger kitty danger kitty

              And q, my life hasn't been all bad, because of the choices I've made. Namely, I got the hell out of the cities and the rat races and got into a job where I could work around my fluctuating energy levels. Self-employed and in demand.
              The mercury poisoning I fought and wouldn't give up until I had an answer. The things I learned about supplements and herbs are things I needed to know when Fukushima came knocking on my throat. Without that early training I would have been deaded by the end of 2012.
              I wish I could have helped my wife, but she wasn't fond of supplements and herbs. She was a registered nurse and when her sickness came on her so suddenly she went with conventional medicine. They were only too happy to oblige. They got a half a million dollars from her insurance company for no diagnosis and a whole lot of nuclear imaging to speed her decline and no effective treatment. In ten weeks! Guess it's one the doctors just chalk up to bad luck cuz they got no other clue.

              • CodeShutdown CodeShutdown

                DK, the indoctrination is powerful…nurses and docs mantra is 'evidence based medicine'. But the entire science of medicine is biased toward profit. Look at a pharmacopoeia to see how poisonous the entire range of drugs in the doctors 'arsenal'. The profit motive accepts only patentable drugs and the profit mark-up is obscene. A drug costing one dollar may be sold for 1000 dollars.

                Emotional bias is a huge factor in ape-mans beliefs.

                'I'm concerned that much of what journals do is ethically weak.' Editor of British Medical Journal

                ' publishing in top journals is extremely difficult, and rejection rates range from 80 percent to 98 percent.' 'three of the top medical journals rejected 14 out 14 of the top-cited articles of all time in their discipline 'https://newrepublic.com/article/135921/science-suffering-peer-reviews-big-problems

                'from 2001 to 2010, compared with the average of 19 top countries, the U.S. ranks lowest. The risk of death in the US is 76% greater for an infant and 57% greater for children aged 1 to 19, the study found'

                • danger kitty danger kitty

                  Yeah, Code, docs are clueless. In a way I'm very lucky I had so many problems the docs were unable to even recognize or diagnose. It's made me very wary of following medical advice when I've seen so many people die from medical ignorance. I go to them to get tests and possibly some helpful information, but I make the decisions on treatment, and, it's usually herbs & supplements. Kept me alive.
                  And talk about profit motive. My wife had a surgical biopsy, and in the process they used some talcum powder to glue the lung pleura to the chest wall because she'd been getting fluid build up there. The surgeon did very well, he was the only competent person we encountered. 2 grams of talcum powder billed at $600. Surgical grade, but still…

            • q q

              Again, sorry to hear…I was just wondering about the fluoride because of the timing and the association with calcification. Thanks for the reply.

    Causes of False Missile Alerts: The Sun, the Moon and a 46-Cent Chip

    As strange, serious and scary as the erroneous emergency notification Saturday about a missile attack against Hawaii may have been, it was far from the first such false alarm the country has faced.

    Every decade since the dawn of the nuclear age has seen its share of close calls, experts said. During the Cold War, the government routinely dealt with hundreds of anomalies that could have led to a nuclear launch.

    But it is rare for a false alert about an impending missile attack to actually reach the public, said Garrett M. Graff, who has written about the extensive preparations made to allow the government to continue in the event of a nuclear or terrorist attack.

    http://www.fukushima-is-still-news.com/2017/12/more-falsified-data.html

    TOKYO, Dec 20 (Reuters) – Japan's Kansai Electric Power Co said on Wednesday it has used parts in important safety equipment at two of its nuclear plants that were supplied by a unit of Mitsubishi Materials Corp with possibly falsified data.

    The utility has found it is using rubber seals from Mitsubishi Cable Industries with possible falsified specifications in dozens of locations at its Takahama and Ohi nuclear plants, a spokesman said, confirming Japanese media reports.

    The discovery comes after Kansai Electric delayed the restart of one of the nuclear power stations because it needs to make checks on parts supplied by Japan'sKobe Steel Ltd, which, like Mitsubishi Materials, is embroiled in a scandal over product specifications.

    An advisory panel looking into issues related to the shutdown of the Pilgrim nuclear power plant in Plymouth is set to meet for the first time in the new year.

    The 21-member Nuclear Decommissioning Citizens Advisory Panel is scheduled to hold a public meeting on Wednesday at the Plymouth Community Intermediate School.

    The panel was formed last year to advise the governor and Legislature and educate Massachusetts citizens about the planned decommissioning of the state's only operating nuclear power plant.

    It does not have any direct control over the process of shutting down the 46-year-old facility.

    One has to wonder at the thought process…

    A 34-year old Washington State law banning any preparation for nuclear attack could be overturned within the next few weeks, according to one of the sponsors of the bill.

    Sen. Mark Miloscia (R) Federal Way told KIRO-7 Saturday's false alarm in Hawaii — where text messages were sent by the state, falsely warning of a missile attack — should convince lawmakers that a plan and a warning system should be a matter of urgency which should not be constrained by state law.

    In 1984, the Legislature's vote was a symbolic way of putting Cold War-era nuclear disaster preparation in the rear-view mirror. The language that became law was a direct rebuke to the old fears of a Soviet threat to the U.S. — which lawmakers figured — was over.

    The law states emergency planning for natural disasters shall "not include preparation for emergency evacuation or relocation of residents in anticipation of nuclear attack."

    Almost again. Next…

    The reality of this most recent scram is that it was not initially caused by a downed line but by human error. Entergy deliberately drove Pilgrim into a blizzard with full knowledge of the previous history of loss of off-site power (LOOP) and safety equipment failures. NRC risk analysis determined LOOP is an Accident Sequence Precursor (ASP). When one or more other conditions like equipment failure or worker error occur, it could lead to a meltdown that would devastate our entire region, including Boston. To be clear, in 2014 a power line went down due to a rotted pole. That was a LOOP event. This Jan. 4 event was not due to a downed line but began with human error, the decision to operate in a severe storm, that turned into a LOOP. The NRC stood by as the country’s worst nuclear reactor scrammed again. The combination of Entergy’s greed and the NRC’s complicity is an overlooked ASP.

    • Jebus Jebus

      There was no legitimate reason to run Pilgrim on Jan. 4. The lights don’t go out when Pilgrim is down. The grid operators reported there were “no immediate reliability issues.” Because the reactor was offline, Entergy implemented preventative maintenance procedures that could only be done when shut down. However, this begs a question. Why does it take a scram in order for preventative maintenance to be completed? In fact, safety relief valves were leaking again and were repaired at this time. Why wasn’t that a concern when the reactor was operating?

Manual swap-over of pressure control to the backup damper restored differential pressure to required limits allowing exit from TS LCO 3.6.15 and restoration of the Shield Building safety function.

    "The Shield Building ensures that the release of radioactive material from the containment atmosphere is restricted to those leakage paths and associated leakage rates assumed in the accident analysis during a Loss of Coolant Accident (LOCA). The Emergency Gas Treatment System (EGTS) would have automatically started and performed its design function to maintain annulus vacuum within required limits.

    US_NPS VA_Surry_1 @ 100 % AUTO-START OF EMERGENCY DIESEL GENERATOR DUE TO TRANSFORMER FUSES BEING DISCONNECTED https://www.nrc.gov/reading-rm/doc-collections/event-status/event/2018/20180118en.html#en53170

    "At 0952 EST on 01/17/2018 with Unit 1 and Unit 2 operating at 100 percent, the normal supply breaker to the Unit 1J Emergency Bus tripped open due to an under-voltage condition when the potential transformer fuses were inadvertently disconnected.

    This resulted in a loss of power to the Unit 1J Emergency Bus from its normal off-site power supply.

    Number 3 Emergency Diesel Generator automatically started on an under-voltage signal and loaded onto the Unit 1J Emergency Bus, as designed.

    "All equipment performed as expected during the event and there were no unexplained occurrences.

    Maintenance has verified the fuses have been reconnected and at 1221 EST, off-site power was restored to Unit 1J Emergency Bus.

    At 1254 EST Number 3 Emergency Diesel Generator was secured in accordance with Station Operating procedures.

    "All Electrical distribution systems have been restored to a normal alignment.

    "There were no radiation releases due to this event, nor were there any personnel injuries or contamination events.

    [ ' potential transformer fuses were inadvertently disconnected '; human error or is this a coverup of an attempted sabotage ]
