Radioactive Rain in Virginia?
I have been monitoring radiation in my area since before Fukashima and my background has always been between 7-18 around my apartment. My monitoring location, in my apartment, has been a steady 14 CPM average for months now. A few days ago I registered readings of 33 CPM, and now for the last 24 hours I have been reading elevated readings too.
For a 24 hour day, an average changing by even 1 CPM is significant. The reason is that there are 1440 minutes in one day and they are added and averaged. Total_daily_counts / 1440 = average CPM.
Here are some of my results for just the last two days
The first few pages are showing you my nice 14 CPM baseline. The last are from the rain.
