Because reports of the residual effects of the Fukushima meltdown has largely disappeared from the media, it is good to see that people at this website, who seem very well informed, are reporting this important information. In this excellent video Arnold Gundersen provides a very clear explanation of one radiation hazard we in the Seattle area (likely in many areas of the West coast and beyond) may be exposed to.
