More than 60 drinking water sampling locations reported results in the United States in 2018 as part of the RadNet monitoring network. Drinking water samples are typically collected four times a year from taps and are sent to the EPA’s National Analytical Radiation Environmental Laboratory (NAREL) for analysis. Each of…
The EPA monitors beta particles as part of the RadNet network through routine laboratory air filter analysis. RadNet air filters are sent to the EPA’s National Analytical Radiation Environmental Laboratory (NAREL) for measurement of gross beta air concentrations and further analysis if warranted. Analysis results for beta measurements on air…
RadNet operators ship air filters from the monitoring location to the EPA’s National Analytical Radiation Environmental Laboratory (NAREL) for analysis. RadNet sample analysis on air filters is conducted following a routine schedule, unless analysis is accelerated after an emergency event. All air filters go through an initial screening for beta…
Under the Safe Drinking Water Act (SDWA), the EPA sets legal limits on the levels of certain radionuclides in drinking water. These limits are applicable to all federal, state and local jurisdictions, including local city public works facilities. Under SDWA, the Agency established a dose-based Maximum Contaminant Level (MCL) for…
The RadNet system provides continuous, near-real-time measurements of radiation levels across the country during normal and emergency conditions, and it is the only national radiation monitoring system in the United States. RadNet's laboratory analyses provide greater analytical sensitivity and have the capability to measure the samples using a wide range…
Under the Safe Drinking Water Act (SDWA), the EPA sets legal limits on the levels of certain radionuclides in drinking water. Under SDWA, the Agency established a dose-based Maximum Contaminant Level (MCL) for beta particle and photon (gamma) radioactivity of 4 mrem/yr. The MCL is based on lifetime exposure criteria…
The EPA placed 140 monitors across the country to provide overlapping coverage with wide-area, nationwide monitoring in mind. If a monitor is not operational in one area, or is being repaired, the EPA's network will still be able to detect any regional fluctuation in background levels of radiation because of…
Having a monitoring system in place to screen drinking water for radionuclides ensures that in the event of an emergency the RadNet monitoring system is able to measure radionuclide levels in local water supplies. This is valuable inform which can help to inform decision makers whether protective actions or additional…
