The radiation in the air due to the Fukushima meltdown does not seem to have been high enough to effect human beings. But there is one species it has devastated: butterflies. Exposure to radioactive material released into the environment has caused mutations in butterflies found in Japan.
Two workers at the reactor were killed by the 50-foot-high tsunami, but the fear that the victims of the radiation that spewed from it would number in the thousands never materialized. In fact, the "hot spots" in Japan showed radiation at the level of .1 rem, a number that’s small compared with the radiation that people in Denver live with every day (a rem is the unit of measurement used to gauge radiation damage to human tissue).
