This test is not suitable for homeowners. This is a nondestructive test, and the sample can be returned if desired. Pure alpha and beta emitters are not measured by this analysis. A gamma scan identifies and quantifies radioactive elements that give off gamma rays. The container is sealed and then it is stored for 30 days before it can be analyzed. The source of the gamma contamination can be natural or man-made.įor this analysis, a dried and finely ground sample is placed in a container specifically designed for gamma scans.
The method can be adapted to most solid materials that can be ground or chopped into small pieces. Purpose: To determine the presence of gamma-emitting isotopes in solid materials such as soil, sand, sediment, and sludge. Environmental Protection Agency recommends that all homes have the air tested for radon. Some states have additional requirements for radon testing providers. Labs that are RMP listed have demonstrated proficiency in the measurement of radon in air. The Radiochemistry lab is certified by National Radon Proficiency Program-American Association of Radon Scientists and Technologists (NRPP-AARST) to perform short-term passive radon 222 testing. It is critical to follow the instructions on the lab form as closely as possible to ensure an accurate result. The vial is allowed to sit for at least 12 hours before it is placed in a laboratory instrument that measures the amount of radon in the vial. When the sample is received at the lab, a chemical called liquid scintillation cocktail is added directly to the plastic vial. This kit contains a plastic vial with a small insert containing charcoal and a desiccant to absorb moisture. The radiochemistry lab offers a two-day screening kit.

This is not a test for the average homeowner. Postal Service (USPS) and placed on a laboratory instrument that measures the amount of alpha and beta radioactivity on the filter. The samples are sent to the lab via the U.S. Air is drawn through a filter for about one week using a special pump. Samples are collected from strategic locations around nuclear power plants in and bordering Wisconsin.
The Radiochemistry Unit performs gross alpha/beta air analyses for the Wisconsin Department of Health Services (WDHS). The source of the alpha/beta contamination can be natural or man-made. It is not possible to determine the levels of radioactivity from specific isotopes with this test. The test does not pick up contamination by radioactive substances that are pure gamma emitters. Purpose: Rapid screening test to determine if air samples show alpha or beta contamination. Water Analyses (Safe Drinking Water Act).
