Tokyo, Oct 30 : A total of 269 cases related to the crippled Fukushima nuclear plant work in Japan have been deemed as job-related accidents and covered by compensation since the nuclear disaster in 2011, Labour Ministry officials said. The compensation claims that have been passed refer to the period since the nuclear accident in March 2011 through October 1 this year, Xinhua news agency quoted the officials as saying. Among them, six cases of workers developed cancer or leukemia because of radiation exposure, and four suffered from overwork-related illnesses, according to the Ministry of Health, Labor and Welfare officials. Currently, about 4,000 people still work on site of the Fukushima plant decommissioning every day, with many at risk of radiation exposure, local media reports said. The decommissioning work has been under way since nearly 10 years ago when the massive earthquake and tsunami devastated northeastern Japan and triggered meltdowns at the Fukushima Daiichi nuclear plant. Tokyo Electric Power Company Holdings Inc. (TEPCO), the plant operator, said three people died between fiscal 2011 and 2019. The company said a total of 98 people suffered from heat-related illnesses between fiscal 2011 and 2019, as they had to wear less permeable masks and protective gear in the scorching summer heat. Moreover, a total of 313 accidents have occurred in the same period of time at the site of the Fukushima Daiichi plant, including several fatal cases in which workers fell into a tank, TEPCO said. /IANS
