It will take time for EPA to add exposure rate measurement to all locations. As part of normal RadNet maintenance, EPA is adding exposure rate measurement capability as we repair a monitor’s gamma detection system. Twelve monitors have already had exposure rate measurement added due to the need for repairs to the gamma detection system.
By the end of 2016, the 10 most populated U.S. cities and Washington, D.C will have exposure rate measurement capability.
We want every state to have at least one station with exposure rate measurement capability as soon as possible. As permitted by additional funding, each state or territory that does not have exposure rate measurement capability will have it added to its largest city that has a RadNet air monitor. This may take several years.
All RadNet stations will continue to report gross gamma count rate, and laboratory analyses will remain the same.
