Abstract

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).
