Fukushima worker was ordered to shield dosimeter with lead cover to make integral dose look low
Fukushima workers were ordered to shield their dosimeter with lead covers to make the integral dose look lower than actual. The lead cover has a few mm of thickness. Some of the workers admitted they covered the dosimeters with lead cases in the interview with Asahi newspaper.
They are working for one of the subcontract companies called “build-up” [Link].
On 12/1/2011, 10 of the workers were ordered to shield the dosimeters called APD, but 3 of them rejected it. In the evening of 12/2/2011, those workers and 3 managers had a discussion at the hotel, where they used as lodging house. The workers recorded the conversation by mobile phone to publish the fact that they were to shield their dosimeter. The manager (54) who gave them order is denying the contents of recorded conversation. He’s denying that he ordered them to shield or some of the workers actually covered it with lead case.
The company “build-up” is a construction and temporary staffing company under TOKYO ENERGY & SYSTEMS INC [Link], which is a group company of Tepco.
The slogan of “build-up” is Make clients 120% content and make employees 120% happy.
