I live in the Spokane area and have been very concerned about the high readings from the monitor there. Now I noticed a second monitor there and that readings are much lower. I am not very knowledgeable about how all of this works, so can someone explain to me why the huge difference in readings?
Thank you!
Welcome to NETC!
It helps greatly when you list the station ID/ID's your talking about. If your a chart member, a copy and past of the stations live chart link is better.
I assume the first station you mentioned has an ID that starts with a 5: which is an EPA gamma station. The second you mentioned I believe starts with a 4: which is an EPA beta station.
The EPA uses better (more sensitive) equipment than most private users own and as a result gets more CPM in the same radiation area/conditions.
Your trying to compare apples with oranges. Only compare a station against its own previous data or against patterns/trends from another station not CPM.
