Radiation environments typically refer to hospital radiology departments, radiotherapy departments, dentistry departments, DSA interventional departments, and nuclear medicine departments where radioactive isotopes are applied. The Area Radiation Monitoring System is essential in such workplaces for monitoring real-time radiation dose levels in environmental areas, providing real-time data and alarm notifications to ensure the radiation safety of medical staff while addressing public concerns about radiation exposure. With visible monitoring data, departments can enhance their radiation safety management capabilities and provide scientific and effective monitoring data to environmental and health supervision authorities, contributing to China's environmental protection efforts.

Purpose of Establishing an Area Radiation Monitoring System in Radioactive Workplaces

The radiation hazards associated with radiological diagnosis and treatment have long been a concern but are rarely subject to comprehensive quantitative supervision. This creates hidden worries for patients, their families, and even medical staff. In the current era of digital healthcare and growing medical informatization, this situation affects the treatment experience and service evaluation of patients and their families regarding radiological diagnosis and treatment disciplines, as well as the job satisfaction of medical staff. Without reliable radiation environmental monitoring data, it is impossible to dispel public doubts, which may negatively impact the social image of radiological diagnosis and treatment departments. Therefore, establishing an area radiation monitoring system helps to monitor radiation dose levels in the workplace, provide real-time warnings, and store, analyze, and statistically process monitoring data. It also improves the management of radioactive equipment in departments, enhances radiation safety management levels, and facilitates supervision by regulatory authorities.

Definition of the Area Radiation Monitoring System

The ionizing radiation area monitoring system provides multidimensional radiation monitoring data and environmental radiation safety information. In abnormal situations, it promptly alerts to unusual environmental radiation levels, automatically indicates restricted areas for patient activities, and prevents medical staff and patients' families from unintended exposure. Additionally, it provides monitoring data and analytical reports to higher authorities, reducing the labor costs of daily monitoring for medical institutions.

Application Scenarios of the Area Radiation Monitoring System

Primary application environments: Nuclear medicine (PET-CT, E-CT, SPET-CT, thyroid cancer treatment, inpatient monitoring of thyroid cancer patients, etc.), radiotherapy (linear accelerators), radiology departments (CT, DR), and interventional DSA application sites.

Supervision Approach

Strengthen environmental radiation safety monitoring, particularly in storage rooms, dispensing rooms, medication dispensing rooms, consultation rooms, waste storage areas, patient rooms, and public areas, with a focus on radiation dose levels in key regions.
In accordance with GB-120 and WSS-533 requirements, this system utilizes environmental radiation dose detection technology to enhance patient management and automatically alerts medical staff when patients enter uncontrolled areas.

Key Features of the Area Radiation Monitoring System

1. Real-time monitoring of environmental radiation dose
The system deploys monitoring devices based on the aforementioned monitoring objectives. These devices support 24/7 continuous radiation dose monitoring and report real-time radiation monitoring data to the monitoring center, where the software displays and stores the data.
2. Remote and local synchronous display of monitoring data
Monitoring devices feature an LCD screen for on-site display of real-time radiation dose values and provide alarm indicator lights to show the current monitoring status. On-site real-time monitoring data is synchronized with the monitoring center software, allowing users to intuitively view radiation dose values at all monitoring points.
3. Support for network transmission
Considering the convenience of device installation and maintenance, the system offers multiple data transmission options, including RJ45 Ethernet interface, Wi-Fi wireless transmission, or 4G IoT communication.
4. Synchronous display of alarm information locally and remotely
Users can set alarm thresholds independently. When a monitoring device detects an alarm, it provides local audible and visual alerts while synchronizing the alarm to the monitoring center for simultaneous notification.
5. Remote configuration functionality
Device menu configurations can be adjusted remotely. Users can configure parameters such as alarm thresholds and system settings based on on-site requirements.
