Monitoring Gamma Radiation

The Neighborhood Environmental Watch Network, known as NEWNET, is able to give early indications of increases in radiation due to radioactive particulates in the air.

1/9/2006Mike McNaughtonAt 9 PM UTC, Jan 9, 2006, the multiplier for the Area G South PIC was changed from 1.055 to 1.11.Station InfoData Graph
7/8/2004Ed LopezThe gamma spike (70.70 miroR/Hr.) at this location on June 29, 2004, was a result of two on-site disposal of "hot cells" from TA-48...Station InfoData Graph
3/5/2004Ed LopezSeveral small spikes have been recorded during the first week of March 2004 due to the recent rain and snow storms. These are seen as small peaks with a longer tail on the right side of the peaks (evidence of radon/thoron decay).Station InfoData Graph
2/26/2004Ed LopezThe gamma spikes recorded on the Area G NEWNET Stations, on February 22 and 24, 2004, were caused by snow and rain on those dates.Station InfoData Graph
11/24/2003Allen TreadawayThe 12 Vdc battery was changed at the station due to flucuations in data. A new battery was installed and tested. At the visit to the RF repeater, we observed that the small 12 Vdc, 7.0 A/hr battery terminals (backup to charger for RF modem) was heavily corroded. These were cleaned and greased. The battery measured 13.6 Vdc and so was left in place. Notes were made in the station logbook.Station InfoData Graph
11/23/2003Mike McNaughtonThe 26.27 mR/h reading at 11:15 GMT 11/23/03 and the incorrect pressure and temperature readings were caused by a low battery voltage, which dropped sharply from 10.1 V to 9.3 V.Station InfoData Graph
10/9/2003Ed LopezTelephone connection was restored on Oct. 9, 2003. Data for the last three days was down-loaded with no data gaps.Station InfoData Graph
10/8/2003Ed LopezThe telephone line transmitting data from the Area G South NEWNET Station is not operational. A work request to fix the problem was submitted on Oct. 6, 2003.Station InfoData Graph
7/15/2003Ed LopezThe gamma spike of 24.8 microR/hr. on July 15, 2003, at approximately 10:00 AM (4:00 PM GMT) was the result of a Low Level Waste (Hot Cells) Disposal from TA-48.Station InfoData Graph
