There is a place for legitimate criticisms of the fat-cat, irresponsible, faked-safety-report culture in the Japanese nuclear industry. However, many concerns by opponents are completely overblown and their ignorance of the science makes all activists look uninformed. Take fears of radioactive iodine crossing the Pacific Ocean and possibly affecting people in California. Those trace amounts which do reach us will most commonly be I-131 which has a half life of 8 days. If it gets absorbed into plants and the plants grow for a month or two before harvest, and then are sent to the green grocer then, by the time it reaches your shopping basket, it would have been degraded by about 4 or 5 half lives, which effectively means there is none of it left.
