Radioactive source safety monitoring system

Abstract

The invention discloses a radioactive source safety monitoring system comprising a radioactive source pot, a positioning sensor, an inspection tour device, and a central processor. The positioning sensor is fixed to the radioactive source pot. A radiation dosage detecting element is fixedly arranged on the inspection tour device. The positioning sensor and the inspection tour device are in wireless communication connection with the central processor. The positioning sensor is fixed to the radioactive source pot and may transfer the positional information of the radioactive source pot any time in order to facilitate positioning and tracking. The radiation dosage detecting element on the inspection tour device may detect the radioactive source pot in order to transmit a detection result to the central processor to be analyzed and processed. The inspection tour device can be placed beside the radioactive source pot to perform detection or can be held by a worker regularly to perform detection, and is not required to be fixed to the radioactive source pot. Thus, the inspection tour device and the radioactive source pot are separated and are prevented from contacting such that the radioactive source safety monitoring system is not liable to damage and is easy to maintain.

Description

technical field [0001] The invention relates to the field of radioactive source monitoring, in particular to a radioactive source safety monitoring system. Background technique [0002] At present, there are many implementation schemes for online monitoring of radioactive sources on the market, but in summary, the monitoring schemes are not comprehensive, and there are disadvantages such as low online rate of monitoring equipment operation, easy damage of equipment, and high investment cost of schemes. [0003] There are mainly two types of existing radioactive source monitoring schemes: [0004] Option 1: Bind the sensor on the radioactive source tank, and realize the upload of the dose and displacement data of the radioactive source through the monitoring sensor physically bound to the radioactive source tank body, so as to achieve the safety supervision of the radioactive source; [0005] Option 2: To achieve the safety supervision of radioactive sources by equipping rad...

AI Technical Summary

Problems solved by technology

[0007] Option 1: 1. Low online rate: radioactive sources often need to work in the field, and most of the workplaces are in signal shielding bodies, resulting in a very low online rate of the monitoring solution in actual use, increasing monitoring blind spots, and causing the monitoring system to lose supervision Effect;

[0008] 2. Poor battery life: the radioactive source has been working in the field for a long time and there is no external power supply in the field workplace

The solution does not guarantee battery life and charging issues during the operation of radioactive sources

Unable to ensure continuous upload of monitoring data;

[0009] 3. Vulnerable: The sensor and the radioactive source tank are physically hard-connected, and the use environment of the radioactive source tank is harsh, and the physical binding between the high-precision sensor and the radioactive source tank is easily damaged, resulting in failure and increasing maintenance costs;

[0010] 4. Low service life: the sensor uses GM tube as the detection element, and it is easy to cause saturation of the GM tube when it is fixed on the surface of the radioactive source tank for a long time, which greatly reduces the service life and increases the maintenance cost;

[0011] 5. Inconvenient maintenance: because the scheme requires the monitoring sensor to be firmly connected to the radioactive source tank (anti-sabotage, anti-disassembly), but the relevant national regulations require that strict protective measures be taken when working on the radioactive source tank at close range

Therefore, it is very inconvenient and costly to carry out routine maintenance on the monitoring sensor

[0012] Solution 2: 1. This solution shows a one-size-fits-all feature, and it cannot match the inspection requirements that meet the needs for different states of radioactive sources, resulting in high implementation costs for customers in actual use;

[0013] 2. This program cannot help enterprises improve their own management level
