A man who worked at the Fukushima nuclear power plant in Japan during the disastrous 2011 meltdown has had his thyroid cancer recognized as work-related. The case prompted the government to finally determine its position on post-disaster compensation.
The unnamed man, said to be in his 40s, worked at several nuclear power plants between 1992 and 2012 as an employee of Tokyo Electric Power Company Holdings Inc. He was present at the Fukushima Daiichi nuclear power plant during the March 11, 2011 meltdown. Three years after the disaster, he was diagnosed with thyroid gland cancer, which the Japanese Ministry of Health, Labor and Welfare confirmed on Friday as stemming from exposure to radiation.
The man’s body radiation exposure was totaled at 150 millisieverts, almost 140 of which were a result of the accident. Although this is not the first time that health authorities have linked cancer to radiation exposure for workers at the Fukushima plant, it is the first time a patient with thyroid cancer has won the right to work-related compensation.
There have been two cases previously, both of them involving leukemia.
The recent case prompted Japan’s health and labor ministry to release for the first time its overall position on dealing with compensation issues for workers who were at the Fukushima plant at the time and after the accident. Workers who had been exposed to over 100 millisieverts and developed cancer five years or more after exposure were entitled to compensation, the ministry ruled this week. The dose level was not a strict standard but rather a yardstick, the officials added.
As of March, 174 people who worked at the plant had been exposed to over 100 millisieverts worth of radiation, according to a joint study by the UN and the Tokyo Electric Power Company. There is also an estimate that more than 2,000 workers have radiation doses exceeding 100 millisieverts just in their thyroid gland, Japanese newspaper the Asahi Shimbun reported.
The 2011 accident at the Fukushima nuclear power plant was the worst of its kind since the infamous 1986 catastrophe in Chernobyl, Ukraine. After the Tohoku earthquake in eastern Japan and the subsequent tsunami, the cooling system of one of the reactors stopped working, causing a meltdown. Nearly half a million people were evacuated and a 20-kilometer exclusion zone was set up.
