…and all of them have been declared as safe! The Pentagon has recently put online a map of the US citizen who were present in Japan last year during the earthquake and the ensuing radiation leak, and declared that none of them were exposed to doses that posed as health risks.
Details for the 70,000 U.S. military-affiliated populations living in 13 locations across Japan and their radiation exposure levels can be viewed on the website here. The map tracks radiation exposure between March 12 and May 11. Camp Sendai, north of Fukushima showed the highest rate of adult exposure; the estimated adult dose of whole body radiation was 0.12 rem and 1.20 for the thyroid. The Thyroid glands get most affected by radiations. Since the radiation levels detected are within the norms, no personnel has been placed in a medical surveillance program to monitor their long-term health outcomes.
Children living in the Hyakuri Airbase, south of Fukushima, were scanned and they reported whole body exposure of 0.16 rem and 2.70 rem. These children were aged between one- and two-years old. The Pentagon is hopeful of issuing a final radiation dosage estimate and this will include those 8,000 folks who had their external or internal radiation measured directly.
