Description

A single small scintillation with delay-time method is used to measure radon and thoron concentrations in their mixed atmosphere-of absolute measurement of radon and thoron concentrations was discussed. The conditions of using radon to test this method was described and a experiment was designed to prove it. Compare to the reference number, Its margin of error was -2.9%∼+3.4%, and the best time of the measurement of radon was 10-45 minutes. In conclusion, a single small scintillation cell could be used for absolute measurement radon and thoron concentrations. (authors)
