This kit includes a single device, instructions and laboratory analysis. The device must be exposed for 48 hours to 96 hours under normal living conditions.  Once your test 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.  AccuStarCanada.com sell pre-paid return shipping label, so you don't have to worry about potential delay in receipt of test device.  If you buy the return shipping label at the same time as your dosimeter, you'll receive a return envelope ready to use with your dosimeter.  Visit our Return Shipping Label section.

 

The CLS-100 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 patented device configuration produces minimum attenuation of the scintillation signal. Perforated end caps allow air to circulate through the mixture and retain any charcoal dust. A polyethylene cap, capable of sealing tightly, prevents the loss of Radon gas from the vial.

For sample collection the CLS-100 liquid scintillation vial is exposed to an indoor atmosphere under controlled conditions for 46-96 hours. After exposure, the vial is returned to the laboratory for analysis. Scintillation cocktail is added and the Radon allowed an elution period of several hours. The vial is then placed in a shielded chamber for counting.

Alpha particles emitted by the breakdown products of Radon create scintillations, or flashes of light, in the cocktail. A photo-multiplier tube detects these scintillation's, the signal is electronically enhanced and the effect of the alpha particles are counted. Background counts are subtracted and the net counts are entered into a formula with other relevant data yielding quantitative results stated in Becquerel per cubic meter (Bq/m³).
