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.

2/2/1999Ken Gileson 2 feb, 1999 a calibrated sensor was installed at this station. sensor #ky-6259Station InfoData Graph
1/21/1999Ken Gilespower was lost on 15 jan 1999 at 02:28 and restored on 20 jan 1999.a wire inside the solar panel connection box had broken.repaired and restarted .Station InfoData Graph
1/7/1999Ken Gileson 20 december 1998 the station stoped transmitting. on 6 january 1999 it was repaired . the mcm on the data collection platform had locked up and was replaced by mcm#1289A 01970. Station InfoData Graph
11/26/1998Herb MaunuBackground radiation measurements (Gamma) decreased from 16.0 microRems to an average of 10.5 microRems. Connection pins to the detector, radiation monitoring system, and data collection platform were checked, cleaned, and reconnected. A handheld portable radiation survey meter was used for comparison of new radiation measurements. Both instruments indicated identical measurements.Station InfoData Graph
11/12/1998Ken Gilesthe background has changed at this sta.it seems to be a problem with the sensor .this will be corrected as soon as possable.Station InfoData Graph
9/10/1998Herb Maunubackground data has dropped by about 1 half normal value. this is possably due to improper setting of 1013 data platform . Station InfoData Graph
8/28/1998Larry SandersThe station was loaded with NEWNET version R35 software on 8/26/98 at 22:58Z. 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. The existing PIC battery was reading 318.9 volts, it was not replaced. A new 12volt battery was installed at the station. Currently, this station only has a radiation sensor. EPA will install meteorological sensors later. All meteorological inputs will remain shorted until the meteorological sensors are installed.Station InfoData Graph
