Abstract

The invention provides a whole body surface contamination monitor and an over-voltage protection method of the whole body surface contamination monitor. An over-voltage protection device is connected to each output interface of a power supply of the whole body surface contamination monitor in series, when it is detected that a current voltage output by the corresponding output interface exceeds a preset voltage threshold value, only the corresponding output interface of the power supply is controlled to be disconnected from a corresponding connecting device, the failure range is reduced, maintenance staff can quickly troubleshoot failure devices accordingly, the failure processing speed is greatly increased, failure time is shortened, and therefore detection efficiency is improved.

Description

technical field [0001] The invention mainly relates to the technical field of radiation monitoring, more specifically to a whole body surface pollution monitor and an overvoltage protection method thereof. Background technique [0002] As nuclear technology is widely used in material composition analysis, non-destructive testing, measurement and control of production processes, medical diagnosis and treatment, material irradiation modification, food irradiation preservation, biological irradiation breeding, and power plant flue gas desulfurization. In the fields of environmental detection and protection, the radiation protection requirements and awareness of personnel have been rapidly improved. Therefore, the radiation protection monitoring technology has also been developed and improved accordingly. At present, the radiation protection monitoring in the above fields is usually the whole body. The surface pollution monitor, by setting it at the exit of the radioactive work ...
