Exposure didn't sicken plant boss: doc
By MIZUHO AOKI
A radiation medicine expert has concluded the former head of the Fukushima No. 1 nuclear plant did not become ill as a result of radiation exposure, Tokyo Electric Power Co. said Friday.
Makoto Akashi, executive director of the National Institute of Radiological Science, reviewed the cumulative amount of radiation Masao Yoshida, 56, was exposed to since the nuclear crisis started in March and informed Tepco of his view Thursday night, the utility said. Yoshida was relieved of his post Thursday to undergo medical treatment. He was hospitalized Nov. 24.
There has been much speculation that his illness was caused by excessive radiation exposure, as he had led efforts to contain the disaster at the Fukushima No. 1 plant after the March 11 earthquake and tsunami knocked out three reactors.
But the utility again declined to disclose further details on Yoshida's illness or his cumulative radiation exposure since the nuclear crisis started, citing privacy reasons.
