Monitoring system used in open radiation place

Abstract

The invention discloses a monitoring system used in an open radiation place with a radiation source. The monitoring system comprises a plurality of sub-stations and a main station. The sub-stations are arranged at the periphery of the radiation place; each sub-station comprises a radiation detector, an alarming module and an infrared detector, wherein the radiation detector is fabricated to be used for detecting the amount of radiant rays at the periphery of the radiation place and is fabricated with the detecting coverage thereof covering the periphery of the radiation place, the alarming module is fabricated to be used for sending an alarming signal in the case that the amount of the radiant rays at the periphery of the radiation place exceeds the preset amount, and the infrared detector is fabricated to be used for detecting a movable object entering the radiation place. The main station is used for controlling the amount of the radiant rays emitted from the radiation source according to the detecting result received from the radiation detectors of the sub-stations.

Description

technical field [0001] The present invention relates to a system for monitoring the dose of radiation at the boundary of an open radiation site, and more particularly, to a system for monitoring the dose of radiation by means of a radiation dose detector installed at the boundary of the control area. Monitoring surveillance system. Background technique [0002] In the prior art, in order to prevent moving objects such as people from entering the open radiation site unintentionally, the way of installing protective fences or protective pull wires is often adopted. However, this method is not suitable for controlling open radiation sites with a large area or frequently changing locations. In this case, auxiliary personnel are required to patrol the boundaries of the radiation site and artificially prevent other personnel from entering the radiation area. Obviously, this The way of manual inspection does not have intelligent monitoring function. In addition, the existing moni...

However, this method is not suitable for controlling open radiation sites with a large area or frequently changing locations. In this case, auxiliary personnel are required to patrol the boundaries of the radiation site to artificially prevent other personnel from entering the radiation area. Obviously, this The way of manual inspection does not have intelligent monitoring function

In addition, the existing monitoring of radiation dose at the boundary of open radiation sites mostly adopts the method of arranging detectors at the site boundary and installing a host in the control room; pre-embedded or laying cables are often used between the detector and the host for radiation dose monitoring It is not suitable for monitoring open radiation places with large areas and frequently changing positions.
