RadNet: EPA Nationwide Environmental Radiation Monitoring

PA’s RadNet system monitors the nation’s air, ambient exposure rates, precipitation and drinking water for radiation. RadNet has 140 radiation air monitors in 50 states and runs 24 hours a day, 7 days a week collecting near-real-time measurements of gamma radiation. Over time, RadNet sample testing and monitoring results reveal the normal background levels of environmental radiation. RadNet air monitoring results are now available on the RadNet Dashboard. Use the Dashboard to view graphs of gamma radiation monitoring results at a specific location.
