Blue: Sensor stations of the TDRM Network (white = offline; yellow or red = exceptionally high radiation levels)
Green: Sensor stations of the GammaSense Network (light green = offline)
 Data of selected sensor stations of the GammaSense Network are imported by the TDRM Project with friendly permission by the GammaSense Group. With our selection we focus ourselves on locations which best complement the TDRM network (see also complete survey of GammSense stations).
The displayed radiation levels are averaged over a period of one hour. They are updated on the hour.
TDRM is not responsible for the correctness of the imported data.
