Authorities have refused to give a cumulative figure for radiation released from the Fukushima Dai-ichi nuclear plant after estimating in June that fallout in the six days following the quake was equal to 15 percent of total radiation released in the Chernobyl nuclear disaster in 1986. The authorities have been too slow to widen airborne radiation testing, said Tetsuo Ito, the head of Kinki University’s Atomic Energy Research Institute in Osaka.

“The government should have expanded the monitoring area by helicopters much earlier to ease concerns among the public,” Ito said in a telephone interview yesterday.

Officials on Aug. 12 found compost in a kindergarten yard in Tokamachi city, Niigata prefecture containing radioactive cesium measuring 27,000 becquerels per kilogram, Kenichiro Kasuga, an official at the city’s disaster prevention department, said by phone.
