1. Project Background and Objectives
In nuclear medicine departments, continuous X and γ radiation risks are present during the preparation, labelling, injection, and therapeutic use of radiopharmaceuticals. To ensure occupational safety for medical personnel and maintain radiation protection levels for patients and the environment in accordance with applicable radiation protection standards, a hospital is required to establish an intelligent, networked, and high-reliability environmental radiation monitoring system. Such a system enables real-time monitoring of dose rates in critical areas, alarm management, and traceable data recording.
The objectives of the project are as follows:
- Real-time continuous X and γ radiation monitoring is provided for key operational zones within the nuclear medicine department.
- A centralised monitoring platform is established to enable unified data storage and remote access.
- Audible and visual alarms together with historical data statistics are implemented to satisfy regulatory requirements.
- Manual patrol inspections are reduced through automated monitoring, thereby improving radiological protection management.
2. System Overview
The YD-880 Environmental X-γ Radiation Monitoring System consists of radiation detection terminals, data acquisition main units, and supervisory monitoring software. The system employs a high-speed embedded microprocessor and compensation-type GM counter or scintillator detector, and is characterised by high sensitivity, short dead time, fast response, and excellent stability, allowing accurate measurement of X and γ radiation levels in nuclear medicine facilities.
Each unit is equipped with a 3.5-inch colour touchscreen LCD( optional 7-inch, 10-inch, or other custom sizes available upon request).for intuitive real-time display and parameter configuration. Through a TCP/IP Ethernet interface, the units can be directly connected to the hospital’s local area network, enabling centralised multi-point data monitoring and cloud-based management. Monitoring data are automatically saved in the event of power loss, ensuring data integrity and continuity.

| Radioactive waste interim storage area | 1 unit | Environmental contamination risk monitoring |
| Radiological protection office | 1 set | Centralised monitoring and data management |
5. Implementation Plan
| Phase | Activity | Duration |
|---|---|---|
| 1 | Site survey and detector placement design | 1 week |
| 2 | Equipment supply, installation, and commissioning | 2 weeks |
| 3 | Network setup and system integration | 1 week |
| 4 | Training and trial operation | 1 week |
| Total | Overall project duration approximately 4–5 weeks |
6.Warranty and Service Coverage
- Warranty period: 24 months from the date of acceptance.
- Service territory: Local or overseas on-site warranty service shall be determined through commercial negotiation and confirmed in the supply contract.
- Response time: Remote response within 2 hours; on-site response time to be agreed contractually based on service location.
The system is intended for the radiological working environment of hospital nuclear medicine departments. By leveraging the high sensitivity, rapid response, stability, and intelligent networking capabilities of the YD-880 series, the scientific rigour and safety of departmental radiation protection management are effectively enhanced. Following deployment, the system furnishes real-time, accurate, and traceable data to support hospital radiation safety oversight, thereby delivering a higher standard of protection for both medical personnel and patients.
