Exceedingly high radiation levels found inside Fukushima’s crippled reactor buildings

Asahi Shimbun 30th Dec 2020, Exceedingly high radiation levels found inside crippled reactor buildings
at the Fukushima No. 1 nuclear plant were labeled by nuclear regulators as an “extremely serious” challenge to the shutdown process and overall decommissioning of the site.

The Nuclear Regulation Authority (NRA) said a huge amount of radioactive materials apparently had attached to shield
plugs of the containment vessels in the No. 2 and No. 3 reactors. Radiation levels were estimated at 10 sieverts per hour, a lethal dose for anyone who spends even an hour in the vicinity, according to experts.

The finding would make it exceptionally difficult for workers to move the shield plugs, raising the prospect that the plan to decommission the reactors will have to be reassessed.
