Abstract

The invention discloses a radon and daughter measurement device, belongs to the technical field of measurement, relates to the measurement of radon, and aims at ironing out a defect that a conventional radon measurement device is severely affected by temperature and humidity. The device can enable an emanometer based on a static electricity collection method to get rid of the restriction of a drying tube, does not need to dry air, can prompt the progress of the radon exhalation rate measurement technology, greatly improves the capability of the emanometer, and enlarges the application range of the emanometer.

Description

technical field [0001] The invention belongs to the technical field of measurement and relates to the measurement of radon, in particular to a device for measuring radon and its progeny. Background technique [0002] Indoor and outdoor environments, underground spaces, uranium mining and metallurgy production workshops and other places need to monitor and control radon concentration. [0003] There are many types of radon measuring instruments currently in use, which can be divided into: scintillation chamber method, activated carbon method, solid nuclear track method, semiconductor electrostatic collection method, ionization chamber method, etc. according to different measurement principles; according to the sampling method, it can be divided into passive type and active type. Mode. [0004] The scintillation chamber method has high sensitivity, but requires a long measurement time and is easily affected by humidity; the activated carbon method and the solid nuclear track ...
