Your Radiation This Week No 37

Colorado Springs wins and is the most radioactive City in the nation this week. There is no prize.

Thirty-one (31) American cities topped 1,000 CPM this week. There were Thirty-one (31) Cities last week, too. There are Thirteen (13) American cities between 900 and 999 CPM. 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.

Fresno, California stopped reporting for the time being or permanently in December 2015; it is not clear which. We’ll see what happens. In the meantime as a reminder, Fresno’s Five year Radioactive High was 2,504 CPM.
