– #Fukushima I Nuke Plant: Radioactive Strontium from Ocean Soil Off the Plant (EX_SKF, June 25, 2011):
Strontium-89 and strontium-90 have been detected in soil and ocean water, but for the first time they have been detected in ocean soil 3 kilometers off the coast where Fukushima I Nuclear Power Plant is located. The samples from 2 locations were taken on June 2.
The Ministry of Education and Science have announced the detection of radioactive cesium from the ocean soil, but has been silent about strontium.
Strontium-89 (half-life 51 days) was detected at 140 becquerels/kg at one location (off Minami-Soma City), 42 becquerels/kg at the other (off Naraha-machi). Strontium-90 (half-life 29 year) was detected at 44 becquerels/kg at one location, 10 becquerels/kg at the other.
There is no safety standard set for radioactive strontium. The amount detected in regular sampling surveys from 1999 to 2008 at Fukushima II (not I) was ND (not detected) to 0.17 becquerel/kg.
The survey also detected a minute amount of plutonium-239+plutonium-240.
Clearly, no one cares any more in Japan. No major news outlet carried the news, not at least on line. The only paper that carried this news was the Japan Communist Party’s newspaper, Akahata (red flag).
