| Post subject: | What and why are the differences in close report stations |
Hi - I just installed a GMC-320 a few days ago and my site's values are in the 25 to 37 range. There is another site that is about 10 miles away that is reporting in the 200 or better range. Below are the current reporting read outs from each station. The differences have been at a multiple of 10 since I added my site. Why are they so different in the reported range and can someone tell me what the differences are? (My station) NETC.COM © 2014 Station ID 1:EB3ACB22 Martinez, GA, US Click here for data charts CPM: current 25 Low 1 High 37 Average 20, Deviation 4.5 Average over last 10 minutes: 22 PI and GMC-320 Last updated: 2014-01-29 19:29:50 GMT+0000 (Station that is about 10 miles away) NETC.COM © 2014 Station ID 5:429 Augusta, GA, US Click here for data charts CPM: current 202 Low 191 High 402 Average 242, Deviation 26.8 (CPM of Gamma in energy range 600-800keV) Last updated: 2014-01-29 13:28:00 GMT+0000 |

Totally different equipment, one EPA radnet Gamma station and your is a Geiger counter. Netc.com says that you can only compare your station with your Radiation Background Level which is calculated over a three month timeframe. Harlan |

What is an EPA radnet gamma station? Like physically, what is the sensor? A scintillator? A giant size Geiger tube? |
