Expert hits ministry for lack of promptness in test
Report of long-range plutonium find tardy
The science ministry was tardy when it reported last week for the first time that traces of plutonium fallout were found outside the Fukushima No. 1 power plant's compound through tests conducted in June, a nuclear expert said Monday.
It is not clear what caused the plutonium, a heavy element, to drift so far.The ministry said it has no plans to expand its checks beyond the survey's current 100-km radius
, which means that Tokyo — whose massive population could magnify the consequences of any results — will be excluded.
Although it would be better if the government conducted more soil tests outside that range, it would be very difficult because conducting an analysis of strontium and plutonium takes much
longer than it does for cesium, Furukawa said.
