????: Gov’t claims Strontium in Yokohama NOT from Fukushima because no short-lived Strontium-89 — Yet 59 Bq/kg was detected

Published: November 25th, 2011 at 12:30 pm ET


Radioactive strontium in Yokohama apparently unrelated to Fukushima, Kyodo, Nov. 25, 2011 (Emphasis Added):

The science ministry said Thursday that radioactive strontium detected in sediment in Yokohama appears to be unconnected to the nuclear crisis […]

The ministry tested sediment collected at two locations in Yokohama’s Kohoku Ward by the city office and soil in the neighborhood but did not detect strontium 89 with a half-life period of around 50 days, which would have been detected if the incident was related to the Fukushima nuclear crisis.

Strontium-89 in Yokohama [intlink id=”govt-radioactive-strontium-detected-at-2-more-locations-in-yokohama-250km-from-meltdowns-approaching-levels-of-most-contaminated-area-in-fukushima-test-results” type=”post”]detected in Mid-October[/intlink]

In a test conducted by the Isotope Research Institute in Yokohama at the request of the city office, the private institute measured both strontium 89 and strontium 90, and detected 59 to 129 becquerels per kg of strontium.

Regarding the significant difference in figures detected by the ministry and the institute, the ministry said the institute’s test may have also detected radium and other radioactive substances [??? Does this explain the presence of Strontium-89?] not related to a nuclear plant accident.

Kyodo also notes the recent Strontium at several places in Tokyo

Meanwhile, radioactive strontium has been detected in soil samples taken from three locations in downtown Tokyo, a citizens’ group said Thursday.

Soil collected from outside the Ministry of Economy, Trade and Industry, and the Tokyo International Forum, both in Chiyoda Ward, and the Kiyosumi-Shirakawa subway station in Koto Ward measured 48, 51 and 44 becquerels per kg […]

The Tokyo amount of strontium-89  has yet to be determined, via EX-SKF:

Iwakami cautions that radioactive strontium may be confirmed to have come from Fukushima only after the detailed analysis at a laboratory that can separately measure strontium-89 and strontium-90. […] I believe there is only one or two laboratories in Japan that does that; one of them is the laboratory that TEPCO uses for the radionuclide analysis (Japan Chemical Analysis Center).

    The strange case of solar flares and radioactive elements


    When researchers found an unusual linkage between solar flares and the inner life of radioactive elements on Earth, it touched off a scientific detective investigation that could end up protecting the lives of space-walking astronauts and maybe rewriting some of the assumptions of physics.

    It’s a mystery that presented itself unexpectedly: The radioactive decay of some elements sitting quietly in laboratories on Earth seemed to be influenced by activities inside the sun, 93 million miles away.

    They didn’t find any? Maybe they didn’t look for it. It sure seems like they don’t want to find any strontium 89 so they can claim that it is not TEPCO’s responsibility. What can you expect from a corporate institution that seeks profit first?

  • Bobby1

    The apartment building in Yokohama where strontium was first measured was built in 1995. Was there another Fukushima after that they didn’t tell us about?

    I think this makes a strong argument for the abolishment of nuclear energy. Clearly there are more radiation leaks going on than are reported and clearly the industry has very little control over their waste products. If this material isn’t from Fukushima then it is from another unreported source without a doubt linked to nuclear energy.
    Lets get rid of nukes before the nukes get rid of us!

      @ Manymoons, we all have Internet and can use Scroogle, right?

      Have a look, please:
      :Metastron (strontium-89) is a sterile, non-pyrogenic, aqueus solution of St rontium-89 Chloride for intravenous administration. The solution contains no preservative.

      Each milliliter contains:

      Strontium< Chloride 10.9 - 22.6 mg Water for Injection q.s. to 1 mL The radioactive concentration is 37 MBq/mL, 1 mCi/mL, and the specific activity is 2.96-6.17 MBq/mg, 80-167 μCi/mg at calibration. The pH of the solution is 4 - 7.5." and: "Strontium-89 Chloride is retained in metastatic bone lesions much longer than in normal bone, where turnover is about 14 days. In patients with extensive skeletal metastases, well over half of the injected dose is retained in the bones. Excretion pathways are two-thirds urinary and one-third fecal in patients with bone metastases. Urinary excretion is higher in people without bone lesions. Urinary excretion is greatest in the first two days following injection." What do we learn from this? Hmmm? mmmkay!

      • Human0815

        Strontium-89 is a pure beta emitter and Strontium-89 Chloride selectively irradiates sites of primary and metastatic bone involvement with minimal irradiation of soft tissues distant from the bone lesions. (The maximum range in tissue is 8 mm; maximum energy is 1.463 MeV.) Mean absorbed radiation doses are listed under the Radiation Dosimetry section.

        Clinical trials have examined relief of pain in cancer patients who have received therapy for bone metastases (external radiation to indexed sites) but in whom persistent pain recurred. In a multi-center Canadian placebo-controlled trial of 126 patients, pain relief occurred in more patients treated with a single injection of Metastron than in patients treated with an injection of placebo.

          So smashing your leg with a hammer till every nerve cell is dead will kill the pain too

          Radiological “medicine” is not medicine at all

          The science to back radiation treatment is flawed, as flawed as every other measurement system that calculates human risk models never even factoring in the KNOWN fact that children absorb more strontium than adults (1953 Rand Project Sunshine)

        They inject strontium-89 into bone marrow of bone cancer patients as a palliative to reduce the pain. No other painkiller known can address this kind of pain. The strontium kills the nerve cells causing it.

        Ironically, strontium-89 causes bone cancer as well.

    Can you please check out the 4 minute video posted at Fukushima Diary today.

    The video is by a woman who has been posting quite a few in the US during the crisis.

    Her latest video addresses what she believes to be radiation burns on her child’s arm after the child was exposed to the a recent rainout.

    She took the kid to the doctor, who confirmed likelihood of injury being a burn, now infected with bacteria.

    About eight months have passed since March. That’s about 240 days. For a substance with a 50 day half-life, four and nearly five half-lives would already have passed, so there would probably only be very small amounts of it detectable by now … if they looked REALLY hard, which they of course have an interest in NOT doing.
