Description

Technical Field

[0001] The invention relates to a measuring device for a gas radioactive source, and in particular to an automatic measuring device and method for a gas radioactive source capable of remote control. Background Art

[0002] High-purity germanium detectors are mainly used to measure gamma rays and X-rays. They are widely used in various physical measurements due to their high energy resolution, high detection efficiency and large ray energy detection range (several keV to several MeV). In the measurement of gas radioactive sources, it is often impossible to predict their radioactive intensity. The traditional laboratory measurement method is to manually make the source and then transfer it to the detector for measurement. This method has the following two problems:

[0003] (1) If the radiation source is too strong, it will cause strong radiation to the test personnel, and personal safety cannot be guaranteed;

[0004] (2) If the radiation source is not suitable for the range of the detector, it is necessary to manually re-produce the source or take attenuation measures. The above process is too complicated and time-consuming, which is not conducive to the measurement of nuclides with short half-lives.

[0005] Therefore, there is an urgent need for a gas radiation source measurement device and method that can solve the above problems. Summary of the invention
