Description
Technical field
The present invention relates to field of measuring technique, particularly the particle activity sniffer of a kind of α and β.
Background technology
Include radioactive indicator in the water quality conventional index that GB " drinking water sanitary standard " GB5749-2006 specifies and limit value, and provide standard (non-limiting values): total α is less than 0.5Bq/L, and total β is less than 1Bq/L.When radioactive indicator exceeds standard, Radionuclide analysis and evaluation should be carried out, can judgement drink, and regulation in " Drinking Water water quality reference index and limit value " that GB5749-2006 provides: the limit value of radium 226 and radium 228 is 5pCi/L (0.18Bp/L), and the limit value of radon is 300pCi/L (10.8Bq/L).
In correlation technique, total α of potable water and total β detects the test in laboratory method (total α and β obtained does not comprise volatility radioactive nuclide in water) that can adopt sampling according to " drinking water standard method of inspection " (GB5750.13-2006), concentrate, measure.But, in existing potable water, total α and β is by after sample concentration sample preparation, the two sudden strain of a muscle detectors of gold silicon surface barrier, α β etc. are utilized to measure, but it can not realize online potable water radioactivity survey, main cause is that radiomaterial activity is extremely low in potable water under normal circumstances, and α and Beta-ray range very short, only have α and β in the water very among a small circle of close detector just can be detected, the measurement lower limit of existing detector can not meet the requirement of on-line measurement far away.
