[0016] A time-spectral analysis 220 The Rn measurement method uses the decay time characteristics of radon isotopes to construct a coincidence-delay time spectrum for the nuclear pulse time. 220 Rn- 216 Po coincidences are differentiated from accidental coincidences of background and other radiation, up to the measurement 220 The purpose of Rn concentration, its specific measurement method is as follows:
[0017] A. Constructing time spectrum: Construct a time spectrum for the recorded nuclear pulse time list, and compare the time interval of 3s after each pulse time (20 times 216 Po half-life) 220 Rn and 216 Time distribution of alpha pulses of Po. The first pulse time is used as the start time, and the time interval of each pulse after that is compared with 3s. If it is less than 3s, it is considered a coincidence event until the time interval is greater than 3s; then the second pulse time is used as the next start time, also compared to 3s. By analogy, using each pul...
