A great deal of concern has been generated by recent published reports connecting Half Moon Bay Beach radiation with the Fukushima Daiichi event. The evidence is overwhelming that the radioactivity on the beach is not traceable to Fukushima.
It is important to remember that there are many natural sources of radiation in the environment. With more and more people carrying geiger counters, natural and anthropogenic sources will be discovered. Itʻs important to investigate each source and understand it before automatically linking it to Fukushima.
