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 the precipitation into a bucket for transfer to a shipping container. EPA’s National Analytical Radiation Environmental Laboratory (NAREL) receives the…
You must take refresher training before you apply for recertification to EPA. You should begin looking for available courses well before your current certification expires, because refresher courses may not be available in your area on a frequent basis. However, EPA recommends that you take your refresher training no earlier…

Answer: Persons applying for certification as inspectors, risk assessors, and/or supervisors must apply to EPA before taking the 3rd party certification exam. For more information about applying for certification as a lead-based paint abatement professional please refer to EPA’s Lead-based Paint Professionals page. Question Number: 23002-33448 Find a printable PDF…
Answer: No. In establishing work practice standards for lead-based paint activities, EPA did not intend to prevent the use of EPA/HUD standards. As a general matter, the requirements are not prescriptive but instead state that certain activities be conducted using appropriate documented methodologies. For example, §745.227(c)(3) requires that dust samples…
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 phone networks like 5G.
EPA reports RadNet laboratory results in conventional units, as shown below with their international equivalents: Medium Conventional unit International SI unit Air Filter Curie (Ci) per cubic meter (m3) Becquerel (Bq) per cubic meter (m3) Precipitation and drinking water Curie (Ci) per liter (L) Becquerel (Bq) per liter (L) Results…
Answer: For individuals who have taken courses which included a course test and a hands-on skills assessment, the full certification period for individuals applying under 745.226(a)(1)(i) will run for three years from the date of issuance of certification by EPA. For individuals who have taken courses which included a proficiency…
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 particles as they collect on the monitor’s air filter. Near-real-time data are continually reviewed by computer, and if the results show…
It is very common for natural background radiation levels to change during precipitation events such as rain, sleet or snow. While there are many more factors that affect radiation levels than just precipitation, radon and radon decay products, which occur naturally may be captured in the precipitation and brought to…
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…
