The radioactive source monitoring system is a key device to ensure the safe application of nuclear technology. By continuously monitoring the radioactive intensity, tracking the status of radioactive sources, and issuing warnings for abnormal radiation, it provides efficient safety management support for industries such as industry, medical care, and energy. Its core value lies in the integration of multi - dimensional monitoring technology and intelligent management functions, which reduces the risk of radiation exposure and enhances the emergency response capability.

 

I. Analysis of Core Components and Functions

1. High - precision Detection Module

As the sensing unit of the system, the radiation detector can continuously collect dose rate data of various rays such as α, β, X, and γ. Using embedded microprocessor technology, it can achieve second - level data refresh to ensure real - time monitoring. The multi - probe collaborative working mode allows a single host to connect to more than 8 detectors, meeting the requirements for large - scale area monitoring.

2. Intelligent Data Processing Platform

The monitoring host integrates a 7 - inch touch - screen LCD and a data storage module, with the following functions:

- Real - time display of radiation dose curves and historical alarm records.

- Support for custom setting of alarm thresholds and automatic calibration.

- Remote operation for detecting the probe status (normal/offline/overload).

- Connection to third - party supervision platforms through the Modbus protocol.

3. Multi - level Alarm Mechanism

The system is equipped with a dual - mechanism of audible and visual alarms and relay switch alarms, supporting graded early warnings for upper and lower thresholds. When it detects dose exceeding the standard, equipment displacement, illegal power outage, or out - of - bounds operation, it can trigger local alarms and simultaneously push them to mobile terminals. The alarm records have a power - off protection function to ensure data traceability.

 

II. Technological Innovation and Scenario Adaptation

1. Multi - dimensional Positioning and Tracking Technology

By integrating GPS satellite positioning and base station positioning (CPS), seamless monitoring of indoor and outdoor environments is achieved. The electronic map dynamically displays the position and trajectory of radioactive sources. Together with the video monitoring system, it can retain on - site image evidence, providing technical support for leakage incident investigations and radioactive source recovery.

2. Internet of Things (IoT) Integrated Application

An IoT supervision network is constructed through RFID electronic tags and 3G/4G wireless communication, realizing three core functions:

- Real - time trajectory tracking during transportation.

- Electronic ledger management of inventory radioactive sources.

- Multi - level permission supervision (from provincial to enterprise level).

3. Industrial - grade Reliable Design

With a damage - proof encapsulation structure and anti - interference circuit, it can operate continuously in an environment of - 20°C to 50°C. Built - in vibration sensors and shell damage detection modules enhance the prevention ability against violent theft and illegal movement.

 

III. Industry Application Practice

1. Medical Radiation Safety

Multi - probe systems are deployed in nuclear medicine clinics and radiotherapy centers to monitor the radiation leakage risk of equipment such as gamma knives and CT scanners in real - time. A typical example is a hospital in Fujian, where a monitoring network was installed in the radiotherapy area. Through audible and visual alarms and dose curve visualization, the accidental irradiation accident rate was reduced by 92%.

2. Industrial Flaw Detection and Energy Fields

GPS monitoring modules are added to oilfield logging and industrial flaw detection equipment. Combined with electronic fence technology, the transportation routes and operation areas of mobile radioactive sources are effectively managed. Provincial supervision platforms in Shaanxi, Guizhou, etc., have achieved online trajectory tracking and dual - control management of dose for high - risk radioactive sources.

3. Monitoring of Nuclear Waste Disposal

A system capable of detecting α/β rays is deployed in radioactive waste storage facilities. Through the linkage of temperature and humidity sensors and dose probes, secondary pollution caused by the corrosion of nuclear waste containers is prevented. In the application of this system in a nuclear power plant in the Northeast region, it has successfully achieved zero - failure operation for an average of 3000 hours per year.

 

IV. Development Trends and Industry Value

Currently, the monitoring system is developing in three directions:

- Intelligence: AI algorithms are used to predict radiation diffusion models.

- Integration: A unified management platform integrating radiation data, video streams, and environmental parameters.

- Standardization: Building a cross - regional radioactive source supervision database to support multi - department collaborative emergency response.

As the "safety guardian" of nuclear technology application, the radioactive source monitoring system continuously improves the industry safety level through technological innovation. Statistics show that institutions with a fully deployed monitoring system can shorten the response time to radiation accidents to within 15 minutes, and the incidence of accidental irradiation of personnel can be reduced by 76%, significantly enhancing the social and environmental protection value of nuclear technology application.
