Portable radiation acousto-optic alarm device

Abstract

The invention belongs to the technical field of radiation monitoring, particularly relates to a portable radiation acousto-optic alarm device used for the nuclear power site, and is used for monitoring the radiation situation of a monitoring area in real time and performing acousto-optic alarming. The portable radiation acousto-optic alarm device comprises an alarm lamp (1), a display module (3), a setting module (4), an infrared induction module (5), a voice module (6), a shell (7), a control module (8), a power supply module (9) and a radiation detection module (10). The radiation dose of the monitoring area is detected through the radiation detection module (10) and transmitted to the control module (8), and the dose level is judged by the control module (8) according to the system parameters. The personnel entering the monitoring area are detected through the infrared induction module (5). When someone enters the monitoring area, the infrared induction module (5) triggers signals and transmits the signals to the control module (8), and the alarm lamp (1) and the voice module (6) under the condition of different dose levels are controlled to alarm through the control module (8).

Description

technical field [0001] The invention belongs to the technical field of radiation monitoring, and in particular relates to a portable radiation acousto-optic warning device for nuclear power field use. Background technique [0002] At present, under relevant safety requirements, workplaces such as nuclear power plants, mining areas, and radioactive laboratories need to be equipped with regional radiation monitoring devices. In particular, the radiation level in the nuclear island plant is relatively complex, with large differences between high and low. In order to facilitate management and control, the radiation area is divided according to the radiation level, and the ALARA principle is implemented to remind operators to pay attention to radiation safety and reduce the risk of accidental exposure. At present, the method adopted by all nuclear power plants is to hang radiation warning signs after manual census and measurement to remind operators of safety precautions. The w...

The warning effect of this method is not obvious, and it is easy for personnel to ignore the identification information

Due to the changeable on-site environment and differences in radioactivity levels, the information on warning signs cannot be updated constantly with changes in radioactivity levels.

When personnel enter or pass through high-radiation areas, it is easy to ignore the warning information on the signs, which may lead to the risk of personnel entering areas with high radioactive levels by mistake. At the same time, it may also cause unnecessary dose exposure, resulting in an increase in the overall level of collective dose
