Problems solved by technology

This method can realize the continuous monitoring of water radon, but the device needs to separate water and gas, the operation is cumbersome, the structure is complicated, and the on-site measurement is very inconvenient. The extraction, transfer, balance and measurement of radon take a long time, which is time-consuming and laborious.
This method has the disadvantage that scintillation vials are easy to be polluted or leak, which will interfere with the measurement results

Abstract

The present invention provides an intermittent continuous sampling water radon measuring device and method. The device includes a sampling part and a measuring part. The sampling part is used to quantitatively collect water samples, and the measuring part is used to measure the radon concentration in the sample. The device structure of the present invention Simple and highly intelligent, it can intermittently and continuously monitor the change of radon content in water, the measurement process is simple, and more accurate water radon concentration can be obtained.

Description

technical field [0001] The invention relates to a nuclear radiation detection technology, in particular to an intermittent continuous sampling water radon measuring device and method. Background technique [0002] The chemical element radon is also called radon. The usual elemental form of radon is radon gas, which is a colorless, odorless, tasteless inert gas and is radioactive. Because radon is a radioactive gas, when people inhale it, the decayed alpha particles of radon can cause radiation damage in the human respiratory system and cause lung cancer. [0003] Radon gas in water mainly comes from the decay release of radium dissolved in water. Radon in drinking water is one of the sources of indoor radon. Usually, 1% to 2% of radon in indoor air comes from drinking water. In special places such as hot springs and water treatment plants, there are serious water radon pollution problems, which may become the largest source of exposure dose; before the earthquake, changes ...
