The latest data on doses taken by workers at the Fukushima Daiichi nuclear plant are available online at the Ministry of Health, Labor and Social Affairs. They were provided by TEPCO. The company has reset all meters to zero by April 1, 2016.

Since that date, and until 31 December 2016, 14,643 workers have been exposed to ionizing radiation at the site of the accidented plant, out of which 13,027 were subcontracted workers (89%). There were 9,484 in December alone, out of which 8,463 were subcontracted workers

The average dose received during these 9 months was 2.14 mSv (2.29 mSv for subcontracted workers and 0.94 mSv for TEPCO employees). The highest dose was 38.76 mSv and a subcontracted worker took it. It should be noted that 93 subcontracted workers have already received a dose higher than 20 mSv. The highest dose taken by a TEPCO employee is 11.63 mSv.

By way of comparison, let us recall that the annual limit dose for the public is 1 mSv per year under normal conditions. For workers, it is 50 mSv per year without exceeding 100 mSv over 5 years. In France, it is strictly 20 mSv per year for workers.
