Fukushima Contractor Accused of Instructing Workers to Falsify Radiation Exposure

Reports have surfaced alleging that a subcontractor at the beleaguered Fukushima Daiichi nuclear power plant instructed its workers to falsify their radiation exposure readings. The firm, identified as Build-Up, is accused of encouraging employees to cover their dosimeters – devices that measure cumulative radiation exposure – with lead casings while in high-radiation zones.

Allegations of Concealment Surface

The primary motivation behind this alleged directive, according to media reports citing the Asahi Shimbun newspaper, appears to have been to under-report the workers' actual exposure levels. This tactic would have allowed the company to continue its operations at the site of the world's worst nuclear disaster since Chernobyl, and crucially, to avoid reaching the legally permissible annual exposure limit of 50 millisieverts. Workers who refused or expressed concerns reportedly left the company.

The Fukushima Daiichi plant suffered catastrophic meltdowns following a massive earthquake and tsunami on March 11, 2011. The disaster led to widespread radioactive contamination and the evacuation of tens of thousands of residents. The ongoing cleanup and stabilization efforts involve numerous workers, often hired through subcontractors, carrying out dangerous tasks in contaminated areas.

According to the Asahi report, several Build-Up workers provided accounts of a senior firm official directing them to use lead casings. The newspaper also indicated that workers possessed a recording of the official's alleged statement, which included phrases like, “Unless we hide it with lead, exposure will max out and we cannot work.” These workers were reportedly on-site for about four months, through March, insulating pipes at a water treatment facility.

Calls for Investigations and Stricter Oversight

The revelations have prompted calls for more rigorous safety management and oversight at the Fukushima site. The Asahi Shimbun urged the plant's operator, Tokyo Electric Power Company (TEPCO), to implement stricter controls over the safety of work crews. Additionally, the influential Japanese newspaper called upon the government to conduct a comprehensive survey of working conditions at the plant, which has remained largely off-limits to the public since the disaster.

The Japanese Ministry of Health, Labour and Welfare has reportedly initiated an investigation into the matter, with details emerging through various news agencies and the Jiji Press.

While officials from the health ministry and Build-Up could not be reached for immediate comment, the allegations raise significant concerns about worker safety and transparency in the complex and long-term decontamination process at Fukushima. Ensuring the well-being of those involved in the cleanup remains a critical challenge amidst the ongoing efforts to contain and eventually decommission the damaged reactors.
