A standard boro-silicate glass VOA sample collection vial with Teflon sepa cap is used for sample collection. 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.
The US Environmental Protection Agency (EPA) suggest to have a radon level in water of maximum 4,000 pCi/L (148,000Bq/m3).
