Elevated Radiation Claimed At Tokyo 2020 Olympic Venues

An anonymous reader writes "A citizens' group in Tokyo claims to have found elevated levels of radioactivity at 39 sporting venues earmarked for the 2020 Olympic Games. Expert and organizers are cautious about the findings but see no problem, as the levels do not pose an immediate threat to human health. From the article: '"It is difficult to have this debate unless we know for sure whether this radiation is from Fukushima or whether it is naturally occurring background radiation," said Pieter Franken, founder of the Japan office of the environmental monitoring organization Safecast."

Fukushima or naturally occurring

'"It is difficult to have this debate unless we know for sure whether this radiation is from Fukushima or whether it is naturally occurring background radiation" -Pieter Franken. I always find this sentiment a little odd. People care too much about if the radiation is measurably above background radiation or what the source of the radiation is. What they should care about is if the radiation is at a dangerous level. We have gotten better at measuring this stuff, so just because we can measure (very small) increases in radiation from Fukushima doesn't mean we should change our lives around it. Anything that is on the same magnitude as background radiation is pretty much safe. For example, you get increased radiation from flying in a plane because the atmosphere is much thinner. Also, natural radiation is much higher near the poles than near the equator, but nobody gets upset about this because it is "natural" like kale.
