What is RadNet?
The EPA's RadNet system monitors the nation's air, precipitation and drinking water to track radiation in the environment.
View ArticleWhy does the EPA test air filters for radionuclides?
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...
View ArticleWhy aren't the results for my location up to date? Why are there gaps in data?
The EPA's RadNet monitors are highly sophisticated devices that occasionally require maintenance and repair. Normally, near-real-time air monitoring data are posted to the RadNet website six times daily.
View ArticleHow did the EPA decide where to install fixed air monitors?
The RadNet system is the only nationwide monitoring network that provides continuous measurements of radiation levels across the United States during normal and emergency conditions.
View ArticleWhat federal standards exist that address radiation in drinking water?
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,...
View ArticleHow does the EPA analyze air filters?
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 conduct
View ArticleWhere can I find results for beta monitoring in air?
The EPA monitors beta particles as part of the RadNet network through routine laboratory air filter analysis.
View ArticleHow does the EPA sample drinking water for radionuclides?
More than 60 drinking water sampling locations reported results in the United States in 2018 as part of the RadNet monitoring network.
View ArticleHow does precipitation affect radiation levels in the environment?
It is very common for natural background radiation levels to change during precipitation events such as rain, sleet or snow.
View ArticleHow does the EPA monitor the air for radiation?
The EPA operates 140 radiation air monitors across the United States as part of its RadNet nationwide monitoring system. RadNet air monitors measure gamma radiation emitted from airborne radioactive...
View ArticleDoes EPA’s RadNet monitoring network track non-ionizing radiation from power...
The EPA’s RadNet monitoring network is designed to track fluctuations in airborne radioactive particles. RadNet does not track non-ionizing radiation that comes from power lines, transmitters, or cell...

EPA reports RadNet laboratory results in conventional units, as shown below with their international equivalents:
View ArticleHow does the EPA sample precipitation for radionuclides?
Samples of precipitation such as rain, snow or sleet are collected at more than 25 stations across the U.S. Samples are collected using specially designed precipitation collection devices which funnel...
