A liquid scintillation spectrometer has been applied to the determination of the counting efficiency for the air luminescence produced by standardized 222Rn and its daughters. Based on the counting efficiency, known amounts of 222Rn can be prepared in 3.5 h. Moreover, the 226Ra source from which 222Rn is collected does not necessary have to be a standard one. In contrast, the conventional method for preparing known amounts of 222Rn usually requires a long waiting period (ca. 15-30 days).
