Device and method for measuring concentration of <222>Rn and <220>Rn synchronously by adopting electrostatic collection and solid nuclear track

Abstract

The invention discloses a device and a method for measuring the concentration of <222>Rn and <220>Rn synchronously by adopting electrostatic collection and solid nuclear track. The measurement device consists of a box body, a third filter, a first aluminum diaphragm, a first solid nuclear track detector, a first filter, a second solid nuclear track detector, a second aluminum diaphragm, a second filter, a high-voltage module, a battery, a base plate and a frame-shaped seal ring. In measurement, the high-voltage module in the measurement device is started up, so that high-voltage electrostatic fields are formed between the inner surface of a first measurement cavity of the measurement device and the surface of the first solid nuclear track detector as well as between the inner surface of a second measurement cavity and the surface of the second solid nuclear track detector respectively, and then the measurement device is placed in a measurement environment to measure the concentration of <222>Rn and <220>Rn in air, and the measurement time is T. After the measurement process, the first solid nuclear track detector and the second solid nuclear track detector are taken off, and are subjected to chemical etching, and the concentration of <222>Rn and <220>Rn in the environment is obtained by calculation.
