LAB FEES INCLUDED IN PRICES. Do-it-yourself testkit includes: boro-silicate glass collection vial, with a Teflon-faced silicone septa insert, easy to follow (illustrated) instructions & a pre-addressed return shipping package.
In the laboratory, a measured aliquot of the water sample is mixed with scintillation cocktail in a glass test vial. Radon preferentially dissolves into the cocktail over 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 picoCuries per Liter (pCi/L).
