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.

7/9/2003Allen TreadawayThe gamma sensor was calibrated on 7/08/03 at about 19:15 GMT. Station InfoData Graph
6/10/2003Allen TreadawayThe gamma sensor failed about 02:30 GMT on 6/09/03. We visited the site, reset the PIC and 1013 display. The gamma values being displayed at the station are correct but the data being transmitted back is not. Another visit to the station will be required for repairs.Station InfoData Graph
10/22/2002April BaldonadoAt 2055Z Kevin Anderson put a calibration source on the gamma detector to perform a calibration test. Source will be removed at 2120Z.Station InfoData Graph
7/29/2002Mike McNaughtonThe 14 microR/h gamma peak at 04:00 Z 16-July-2002 was caused by rain.Station InfoData Graph
6/15/2002Mike McNaughtonThe peak in the gamma data near 2300 June 14 to 0100 June 15 resulted from rain.Station InfoData Graph
3/28/2002Kevin AndersonCalibration results are within the acceptable 5% difference between the observed and expected readings. The station is performing as expected.Station InfoData Graph
3/25/2002Allen TreadawayThe gamma detector, a Reuter-Stokes HPIC, was source checked by K. Anderson on Friday afternoon, 3/22/02, due to a sensor rotation last week. All appears normal.Station InfoData Graph
3/25/2002Mike McNaughtonThe gamma peak at 21:30 Z on 22 March looks like it was the result of a calibration of the gamma detector. Station InfoData Graph
3/20/2002Kevin Anderson On Tuesday 3/19/02, corrected the Barometric Pressure calculation in the Campbell program. Data is collecting and transmitting fine.Station InfoData Graph
3/19/2002Kevin AndersonMonday, 3/18/02, work continued to get the data to transmit. A Yagi antenna was installed. The data is now transmitting. Reporting of the barometric pressure data needs to be corrected. Station InfoData Graph
