HRD-4 Wristwatch-style Personal Dosimeter with 50 keV-1.3MeV Energy Response, 0.10 μSv/h-50mSv/h Measuring Range, and Adjustable Alarm Threshold

The HRD-4 wearable (wristwatch-style) personal dosimeter is designed for measuring personal dose equivalent caused by X and γ radiation. This device is particularly suitable for medical applications in interventional radiotherapy.

Controlled by a low-power single-chip microcomputer, this dosimeter provides comprehensive functionality including LCD drive display, measurement data storage, parameter setting, detector fault alarm, battery voltage detection, over-threshold sound and light alarm, and charging capabilities.

This versatile dosimeter can be applied to radiation dose equivalent measurement in various scenarios including:

• Radioactive medical treatment
• Industrial non-destructive testing
• Radioactive isotope application
• Occupational disease prevention
• Military units
• Nuclear power plants
• Surrounding areas of radioactive workplaces
