Description

Technical Field

[0001] The utility model relates to the technical field of sanitary protection detection, in particular to a radiation sanitary protection detection support rod. Background Art

[0002] According to the requirements for radiation health protection of instruments containing sealed sources, the surface of nuclear instruments is measured at 5 cm and 100 cm from the object. During on-site testing, it is often encountered that the place where the testing instruments are used is one to three meters away from the surface of the source container. Due to the special environment, few people stay, it is impossible for people to enter, or a supervision area is set up in the radiation workplace. In this case, it is difficult for testing personnel to enter the radiation site to conduct protection testing at 5 cm or 100 cm from the surface of the nuclear instrument. When the measuring distance is beyond the reach of the measuring instrument, the surrounding dose equivalent rate can only be calculated using the inverse proportional principle of the distance. If it is the surrounding dose rate of the background level, the measurement result and the measuring distance can only be given directly.
