Utility Says It Underestimated Radiation Released in Japan
TOKYO (Reuters) The amount of radioactive materials released in the first days of the Fukushima nuclear disaster was almost two and a half times the initial estimate by Japanese safety regulators, the operator of the crippled plant said in a report released on Thursday.
The operator, the Tokyo Electric Power Company, said the meltdowns it believes took place at three reactors at the Fukushima Daiichi plant released about 900,000 terabecquerels of radioactive substances into the air during March 2011. The accident, which followed an earthquake and a tsunami, occurred on March 11.
The latest estimate was based on measurements suggesting the amount of iodine-131 released by the nuclear accident was much larger than previous estimates, the utility said in the report. Iodine-131 is a fast-decaying radioactive substance produced by fission that takes place inside a nuclear reactor. It has a half-life of eight days and can cause thyroid cancer.
It is difficult to judge the health effects of the larger-than-reported release, since even the latest number is an estimate, and it does not clarify how much exposure people received or continue to receive from contaminated soil and food. Experts have been divided on the health impacts since the disaster because the studies of assessing radiation risks are based mainly on a different type of exposure the large doses delivered quickly by the atomic bombs in Japan in 1945.
Although people who lived closest to the plant were evacuated, many people remain in areas with significantly higher radiation levels than normal.

(18,541 posts)By the time we know the truth about Fukishima, they're going to have worn their fat little fingers down to nubs working the social media sites.
2.5x or 500x more than we were told is (still) just not that big of a deal, right?
The World Health Organization's - WHO, just a few days ago, released a report saying every little things is gonna be alright.
That report came out just before this report from the plant manager - Tepco.
That WHO report used the previous numbers that are now known to have been minimized.
It is curious that both reports are delivered at almost the same time. Eh?
