Multi-point diffusion type alpha energy spectrum cumulated soil radon measuring method

Abstract

The invention discloses a multipoint dispersive accumulative alpha energy spectrum soil radon-measuring method, which comprises the following steps: A. a measuring point is selected, and a data acquisition unit is buried into the soil of the measuring point; B. after radon gas in the soil is dispersed into a radon gas acquisition chamber of the data acquisition unit, the data acquisition unit is started; C. the data acquisition unit accumulatively collects and measures radon of the measuring point and alpha radiators in daughters of the radon, and then transmits measuring data to an on-scene data management module; D. the on-scene data management module performs statistic analysis on the measuring data, and then transmits the measuring data to a computer analysis module; and E. the computer analysis module further analyzes the data. The method can overcome the defects of the prior soil radon-measuring method, can solve the problems of low measuring efficiency, measuring precision, measuring accuracy and measuring reliability of the soil radon, and can realize qualitative measurement on the radon and daughter nuclide of the radon, thereby being capable of meeting the active demand of the prior geological exploration field and the prior environmental evaluation field on measurement of the soil radon.
