This is about as pathetic as it gets. In order to deal with a new baseline level of radiation across Fukushima (which Japan still refuses to discloses to the world because it is "Under Survey"), the Japanese ministry of health labor has decided to take the unilateral act of scrapping years of safety data, and more than doubled the maximum allowable exposure for nuclear workers from 100 millisieverts to 250 millisieverts. At least we now know that the radiation level around Fukushima is most likely bounded by this range. As to the reason for the increase, the ministry said it is "unavoidable due to the circumstances." In other words, when self-administered Seppuku will not work, just apply it to someone else.
TOKYO—Japan has raised the maximum radiation dose allowed for nuclear workers, citing the urgent need to prevent a crisis at a tsunami-stricken power plant from worsening.
Despite the increase, surging radiation levels forced emergency workers to temporarily withdraw from the crippled Fukushima Dai-ichi nuclear plant on Wednesday, losing time in their struggle to cool overheating fuel in reactors crippled by last week's devastating earthquake and tsunami.
The Ministry of Health Labor and Welfare raised the maximum allowable exposure for nuclear workers to 250 millisieverts from 100 millisieverts. It described the move as "unavoidable due to the circumstances."
Hopefully the US won't promptly implement this cunning ploy to "overfund" pension funds with just one "safety-related" overhaul.
Indicatively, here is how "safe" 250 millisieverts are:
