Abstract

This study examined the accumulation and tissue distribution of radioactive cesium nuclides in Japanese Black beef heifers raised on roughage contaminated with radioactive fallout due to the accident at the Fukushima Daiichi Nuclear Power Station on March 2011. Radiocesium feeding increased both (134)Cs and (137)Cs levels in all tissues tested. The kidney had the highest level and subcutaneous adipose had the lowest of radioactive cesium in the tissues. Different radioactive cesium levels were not found among parts of the muscles. These results indicate that radiocesium accumulated highly in the kidney and homogenously in the skeletal muscles in the heifers.

    What on earth is the point of this 2-6 week study? To convince Japanese that a cow flown in from outer space does not show uneven skeletal muscle cesium after six weeks of contaminated feed??

    How about checking the dozens of legitimate studies done on cattle in Belarus done 15 years ago near Chernobyl? They showed highest concentration in the cow's thyroid, followed by liver, spleen and kidney.

    Or something useful like cows allowed to *pasture* graze in Chernobyl-contaminated Bavarian farms had one-tenth the cesium levels of silage-fed cows? That study is almost 20 years old.

    Cows? The Japanese medical authorities are simply immoral for ignoring the known effect on CHILDREN. Are children in Fukushima so different than those studied in Gomel a decade ago?

    Autopsies on Gomel children <10yrs old performed in 1997 (born AFTER the accident) showed 2-3x the internal cesium concentration as adults. They had pronounced cesium levels in their thyroids, adrenals and pancreas even though they weren't even born (or in utero) at the time.

    Interesting study…it has some value despite care they took to make sure the results weren't terribly disturbing.

    So why were their cesium results not higher?

    1. The research site was fairly far from Fukushima, Daiichi (250 km) or 155 miles. The cows came from there also. So not in the super danger zone for the first months of the disaster.

    2. The experiment covered only 2 to 6 weeks of feeding the heifers. Not quite what we would expect to find from cows fed longer or cows few strictly from free range roughage. They used rye grass harvested from Nasushiobara, Japan which is 63 miles from Fukushima NPP. The city is also southwest from Fukushima NPP and the bad plumes the first two months went north by most accounts. The experiment was conducted in May 2011 (before the next 400 days of bioaccumulation).

    3. In the Total Mixed Ration fed the heifers, there is no mention of how much open range rye grass is mixed into the feed which included corn, soybean meal, "beat" pulp (I assume beet), and a vitamin mix. No indication that the other four ingredients came from radioactive-tainted food stuffs. So maybe the roughage was 10%, 20%, 30% of their diet? Who knows? They do.

    4. Test heifers had uniformly (homogenously) contamination of muscles including the heart and also the liver. The kidneys held the highest levels which is to be expected as they serve the body as a natural filter of the blood, and remove wastes which are diverted to the urinary bladder.

      This is a valuable study because it proves when cows eat radioactive food the posion does gather in the edible parts. People eat meat and drink the milk. Ah ha! The food chain can't be fooled.

      The same can be said for fish.

      Now…how about some strontium tests?
