High radiation levels detected 30km off nuke plant
Japan's science ministry says levels of radioactive substances up to twice recommended limits were detected in waters 30 kilometers off the quake-damaged Fukushima nuclear plant.Read more at www3.nhk.or.jp
The ministry conducted a survey on Wednesday in 8 locations over a distance of 70 kilometers from north to south in the Pacific Ocean. Radioactive iodine-131 and radioactive cesium-137 were detected at all locations.
Levels of radioactive iodine-131 were from 1.05 to 1.92 times higher than the limit. Readings for radioactive cesium-137 were all below the limit, but about 10,000 times higher than a similar survey last year.
Another survey conducted by the Tokyo Electric Power Company on Wednesday detected radioactive iodine-131 at 146.9 times the limit, 330 meters away from a water outlet of the nuclear plant. The same substance was detected at a level 19.1 times higher than allowable limits on the coast 16 kilometers south of the plant.
The science ministry says it will continue analyzing the impact of the radioactivity on marine resources and the environment.
A senior consultant at the Marine Ecology Research Institute, Jun Misonoo, says contamination decreases further off the coast. He says radioactive iodine-131 levels fall by half in 8 days, and the impact on fish fades away.
Misonoo says that although radioactive cesium is unlikely to affect human health, monitoring should continue to assess its impact inside fish.
