It might be worth noting that you are one of the founders of UPower.
WHO estimates the increased cancer risk of people living inside the Fukushima Prefecture as being up to 70% higher (thyroid cancer for girls exposed as infants)[1]. Numerous other studies indicate increased cancer risk[2].
During the Fukushima meltdown, radiation levels of 3–170 μSv/h (= 17 mrem/hour) were measured within 30 km of the reactor[2]. Safe levels are 5000 mrem/year[3].
As I understand it, many argue that these of cancer risk estimates are high. I'll be happy to change my mind once medical scientist working in the field change theirs.
