Used for the initial screening of a home for radon gas. Can also be used to assess the performance of a radon mitigation system. The radon test device must remain undisturbed for 48 to 96 hours under closed house conditions.
Once your radon testing period ends, you have to send back the dosimeter to the laboratory. The vial must reach the laboratory within 7 days of closing, otherwise the test becomes invalid.
The CLS100 is a 6 cm. high by 2.5 cm. diameter high-density polyethylene liquid scintillation vial, able to fit a standard LS rack. The 22 ml capacity vial is designed to hold a small canister near the opening above the scintillating fluid. The canister, made of high-density polyethylene, contains a patented pharmaceutical-grade charcoal-silica adsorption material.

This method employs a small vial containing activated charcoal for sampling the radon. After an exposure period of 2 to 7 days (depending on design) the vial is sealed and returned to a laboratory for analysis. While the adsorption of radon onto the charcoal is the same as for the Activated Charcoal Adsorption method, analysis is accomplished by treating the charcoal with a scintillation fluid, then analyzing the fluid using a scintillation counter. The radon concentration of the sample site is determined by converting from counts per minute.
