Comparing Fukushima and Chernobyl concerning radionuclide distribution and Isotopic variations on Land and effects on the environment. New studies by Timothy Mousseu and his team.
Tim was interviewed and he gave us an overall look at the situation and compares the 2 nuclear disasters for us. Link to Timothy Mousseau cricket.biol.sc.edu/Mousseau/Mousseau.html

Strontium and Plutonium isotopes
“Most of the those other isotopes in are very small quantities relative to the cesium that were released – that were very different to the Chernobyl situation where huge quantities of Strontium, about equal Cesium and Strontium were released along with several isotopes of of Plutonium, The Plutonium is in the process of decaying into Americium and (that) is more radioactive than Plutonium apparent”
Strontium in Fukushima Prefecture
In Japan the the Strontium were not volatilized as did Cesium and Iodine and it did not travel far (on Land) but large quantities of Strontium are still being released by the ground water at the plant and and from the cooling water leaking into the ocean.
Contamination of the Nursery areas in the deep ocean and off the coast of Japan?
On the 4th February 2016 a Press conference was held in the Foreign Correspondents Club in Japan calling for more research funding to be done concerning the Human health effects of the Fukushima nuclear disaster and we find a similar problem faced by epidemiologists and researchers to the lack of interest and therefore funding in this area. During the interview with Timothy we touched on research funding issues in a variety of areas relevant to the nuclear disaster including the aquatic environment. (Some other issues to do with marine contamination here http://www.opednews.com/articles/Off-shore-nuclear-waste-du-by-Shaun-McGee-Earthquake_Earthquake-Faults_Iaea_Information-140712-441.html )
Timothy responded to a question put to him saying that only some studies have been done (to his knowledge) on the bottom feeding fish and that these fish had been found to contain high contamination but that very few other studies have been done. He went on to say;
“surveillance work to determine whether fish can be consumed rather than the biological impacts (and) ecological impacts of the fish themselves, this is one of the important questions and that is one of the interests we have as a group.”
He went on to say that the issues for the authorities are that;
“Whether or not —“ The fish are below regulatory limits for export, that is the main – you know- economic driver of interest but the biological drive is almost nil as far as I can tell”
Terrestrial (land) contamination issues on wildlife, plant and micro–organisms
Of the limited research happening in this area, Tim and his team are at the forefront in developing novel and creative ways to ascertain the effects from the nuclear disaster. Using their experience gleaned from the radiological affected areas of Chernobyl (with the help of Anders Pape Møller, CNRS, University of Paris-Sud) and applying this invaluable experience on the highly affected areas on the mountain sides and hills surrounding the Fukushima city to the coastal areas including Namie and IItate areas of Fukushima and some less contaminated areas for comparison studies.
These studies have resulted in some 8 to 9 primary papers on birds and Insects. Also, new research on Rodents is about to be released and cameras have been set up in various locations studying large mammals such as pigs and monkeys.
Oze National Park in southern Fukushima Prefecture and Northern Chiba Prefecture (north of Tokyo)
On the search for clean areas for comparison studies, Tim said that he was disappointed. He looked at the huge and remote Oze national Park as a possible location (largely situated in the Chiba Prefecture but his radiation readings were more than 10 times normal at 0.5 mcSv/h (compared to the contaminated research area with 30 – 40 and 50 mcSv/h in the hills surrounding Fukushima City.
We talked about the effects of sediment transfer from the mountains down through the lakes and forests of Oze Park. Tim then mentioned a Typhoon he witnessed that stripped large areas of soil into the rivers and was concerned of the effects in the extensive lake system in Oze Park and the result of contamination making its way to the river outflows on the coast and effects on the fisheries. Asked as to whether any studies were being done he said that in the last year (some 5 years after the nuclear accident) many geologists from around the world were vying for funding to commence studies in “the next year or two” studying such issues but presently;
“I don`t know of any studies being done” he said
The issue of funding was mentioned here and that the Japanese government seemed only interested in funding studies for issues around food and health issues – link to issues around health studies being grossly limited here
