Abstract

The invention discloses an on-line measurement method for radionuclides in drinking water. The method comprises three parts of water sample collection, radioactivity measurement and data processing. The water sample collecting part can be used for continuously collecting drinking water into the measuring chamber; the radioactive measurement part can rapidly and accurately measure alpha, beta and gamma radionuclide pollutants in drinking water; and the data processing part is used for processing the obtained nuclear signals in real time, selecting interested signal amplitude spectrums for analysis, and automatically giving an alarm when the counting rate of the signals exceeds a threshold value or the counting rate exceeds a certain degree along with time change. The online measurement method solves the problems that a conventional monitoring method of a water system cannot detect short-term pollution, cannot continuously monitor radioactive pollution of the water system and cannot directly judge whether drinking water is polluted or not. The invention further provides a device for measuring the radioactivity in the drinking water on line.

Description

technical field

[0001] The invention relates to the field of radionuclide measurement, in particular to an on-line measurement device and method for radioactivity in drinking water. Background technique

[0002] Ingestion of radionuclides is one of the ways in which the human body is exposed to radiation, and large intakes of radionuclides increase the risk of cancer, so ensuring a safe water supply is of paramount importance to public health. Drinking water systems are susceptible to contamination by radioactive substances due to accidents or human accidents. Routine monitoring methods for water systems (sampling at regular intervals for laboratory analysis) cannot detect short-term contamination and therefore do not protect people from radiation exposure. In order to monitor radioactive contamination of water systems caused by nuclear accidents, on-site on-line measurements are required to quickly and accurately assess alpha, beta, and gamma radionuclide contamination.
