It has been revealed that the suction survey at an atmospheric observatory in Nagasaki City, about 1000 kilometers from Fukushima I Nuclear Power Plant, showed a high level of radioactive materials one month after the nuclear accident. Toshihiro Takatsuji, associate professor at Nagasaki University reported at an international symposium by Hiroshima University Research Institute of Radiation Biology and Medicine (RIRBM) held on January 25 at Hiroshima University in Hiroshima City.
Professor Takatsuji measured the amount of radioactive cesium in the air captured by the air suction apparatus and on the filter paper at the suction entrance [...]
The week beginning on April 6 registered the highest level of radioactive cesium [...] 11,300 becquerels/kg [...]
Professor Takatsuji pointed out that on April 6, 2011, the wind reached from Tohoku to Kyushu (where Nagasaki is located) in an arc sweeping the Pacific side of Japan [...]
The professor said, “Even if the amount in the atmosphere is low, it is possible that radioactive materials accumulate in the air filters.” The symposium will continue on January 26.
- No information about cesium-137
- Professor Takatsuji has been featured in a popular weekly Shukan Gendai magazine (as transcribed in this blog) in which, with Shinzo Kimura he assures the readers that the effect of radiation won’t manifest in genes in the next generation, so the fear of expecting mothers in Fukushima is overblown
- But even the two admit that by continuing to live in the areas with elevated radiation levels the gene mutation which normally happens after 10 generations or more may happen within a few generation
For comparison, here is a survey using October dust samples by France’s ACRO:
