The ‘one-full body’ CAT scan thing. You used the lower of two numbers - not the one actually recorded low over a bush (kid height?) and apparently chose to ignore the text [and that’s only external exposure]. The kids have been eating and drinking local milk and other foods. Their total internal plus external exposure is unknown - the readings on playgrounds and lawns may be higher. With this clinic - parents will get answers that Japanese officials, and apparently the pediatrician, are not interested in pursuing. I hope it turns out fine - but that’s not an assumption I’d make given the information coming out of Japan detecting excessive radiation in tea leaves 300km from the site.
Detecting radiation mildly in excess of the national standards. There is no indication the radiation is "excessive" in terms of risk or danger, or that the number set by the government might be too low, or too high for that matter.
You used the lower of two numbers -- I quoted from the article. The article used some average number. It wasn't either the high or the low readings taken by the reporter. The article provided no indication that radiation has been measured in the milk the children are drinking -- other articles have indicated that milk and other items ARE being tested, and that milk consumption was stopped when unnatural readings were found, so it is simple speculation that there is a risk in consumption.
If I lived in Japan, I'd spend some money on test equipment, and do enough of my own testing to make myself reasonably sure the risks were acceptable.
