Your Radiation This Week No 34


St Louis Arch in Winter - National Park Service
Thirty-nine (39) American cities topped 1,000 CPM this week; that’s up 5 more cities since last week. Another ten (10) cities are clustered between 900 and 999 CPM; two of them in California. Stay Alert and take all appropriate precautions. The most prevalent isotope, Cesium 137, takes a daunting 600 years to decay to infinitesimal levels and it is not even particularly long-lived radiation. The Cesium will remain for 600 years.
