Frequent Questions

Why does EPA test air filters for radionuclides?

RadNet's laboratory analyses provide confirmation of the near-real-time air monitoring results. Air filters are used on RadNet stationary and deployable monitors. Air cartridges may be used on deployable monitors when radioactive gases may be present, such as following a nuclear reactor accident. By monitoring air and testing air filters on a regular basis, EPA is able to establish normal background levels of radioactivity and detect additional activity from man-made radioactive sources.
