Fukushima Daiichi workers

TOKYO, Japan - File photo in November 2011 shows workers wrapping up the day's work at the crisis-hit Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power Co. in Fukushima Prefecture. They carry alarm pocket dosimeters, or radiation monitoring meters, around the left chest inside their protective suits. Sources said on July 21, 2012, that an executive from a TEPCO subcontractor tried to force its workers at the plant to cover their APDs with plates made of lead in an apparent attempt to underreport radiation exposure.
