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.

8/18/1998Larry SandersThe station was loaded with NEWNET version R35 software today at 18:50Z. This software provides improved accuracy for radiation measurements in the low range. The station was re-wired with a door sensor and new voltage divider for the radiation sensor. A new 12volt battery was installed. The PIC 300volt battery voltage was ok (288.4volts). The relative humidity sensor appears to be working correctly at the station, but data processing software for this sensor at Los Alamos is in error. Software engineers at Los Alamos are working on the problem.Station InfoData Graph
3/23/1998Herb MaunuMeasurements displayed on Mar. 18 (julian day(077)) at 10:39 hrs (PST) and 10:54 hrs (PST)are QA check source measurements for gamma detector operation and system performance. We are evaluatin the humidity sensors and software programs to correct the current problems with the unit.Station InfoData Graph
3/16/1998Herb MaunuHigh radiation measurements displayed on Tuesday March 11(day 070) were caused by a radioactive check source used for QA control. Humidity measurements showing 9999.9 indicates a problem and will be corrected.Station InfoData Graph

2/14/1998Herb MaunuQA radioactive check source measurements were performed on Feb. 5th 09:09 hrs and 09:24 hrs showing 118.8 uR/hr and 44.0 uR/hr. System operating normal.Station InfoData Graph
1/30/1998Herb MaunuQA radioactive check source measurements displayed on Jan. 22nd 12:39 hrs (63.3 uR/hr) and 12:54 hrs (46.1 uR/hr). Also at 13:27 hrs on Jan 27th a reading of 94.0 uR/hr was corded. These measurements are valid for the check source. All hours are recorded in Pacific Standard Time (PST).Station InfoData Graph
