- 3m40s TEPCO shareholders want out of nuclear power
"The government official said that more than 16,000 residents received incorrect estimates. The official has been carrying out the ongoing survey among Fukushima prefecture, 2 million residents. They asked them to fill out the form about their activities during the first 4 months following the nuclear accident. Scientists of the radiological Institute used this form to calculate the exposure estimates. The official gives the residents their results as the data comes in. They said that among those who got faulty estimates more than 12,000 people were given their figure 0.4 mSv/y lower than what was actually correct.
They said that the calculate was based on the wrong dates in the computer program. Fukushima official said even with the correct figure it's unikely the estimated doses would pose the health risk. The annual limit of radiation exposure for the general public in Japan is 1mSv/y. "
I don't understand how the official could say that those who got faulty estimates wouldn't pose any health risk. if it was calculated 0.4mSv/y lower than what was actually correct, surely some of 12,000 people's real exposure estimate could be more than 1mSv/y. In fact some of Fukushima residents actually have been living in the area up to or more than 20mSv/y (= being exposed to external ionizing radiation up to or more than 20mSv/y) without taking into consideration of internal exposure through radioactively contaminated food and drink because the Japanese government has been applying UNSCEAR recommendation (up to 100mSv/y is safe). Talking about 1msv/y regulation in this case doesn't mean anything.
Also WHO' report which was made based on the Fukushima survey report needs to be reevaluated as well.
According to page 13 of the below website, it says “The WHO report is based on preliminary and include only data that were available as of September 2011.” http://apps.who.int/iris/bitstream/10665/78218/1/9789241505130_eng.pdf
Thyroid examination hasn’t started till October 2011. Therefore WHO report was based on what Fukushima Health Survey group did before the end of September, 2011. The collection rate was 47% as of the end of September, 2011.
