USA, CA, Palo Alto, Triple El (2) (sensor 106) Online 5 mins ago 2 years ago 11cpm 2611cpm 0.091μSv/h 21.668μSv/h More sensor data Sensor:LND7128 Model :Hawk Radius Alarm :150 Medcom Hawk Radius dual sensor probe, these are the readings from the energy-compensated tube. Probe is installed pointing down, away from the street. 2 Responses to “USA, CA, Palo Alto, Triple El (2)” Ed Lafargue September 20, 2015 Note about the peaks: these were somehow caused by coupling of the probe with HAM radio antenna. Moved antenna away from installation, and coupling effect seems to have disappeared (2015.09.20) Reply Dan Sythe February 1, 2015 Perfect installation. I love it.
