RD-300 Multifunctional Radiation Detector

Product Introduction

The RD-300 Series Multi-functional Radiation Detector consists of a versatile main unit paired with various external probes—such as intelligent probes for alpha and beta surface contamination, high-range long-handle probes for X- and gamma radiation, high-sensitivity probes for X- and gamma dose rates, and neutron dose equivalent probes. By utilizing a single main unit shared across different probes, the system forms a comprehensive radiation monitoring kit capable of meeting detection requirements across a wide array of settings. It is particularly well-suited for routine radiation protection operations in diverse environments, including nuclear power plants, other nuclear facilities, environmental protection agencies, industrial non-destructive testing sites, and radiation processing facilities.

To accommodate varying radiation measurement scenarios, the device features multiple operational modes, including dose rate measurement, count rate measurement, rapid scanning, timed measurement, and background subtraction. Users can flexibly switch between these measurement modes based on specific field conditions, thereby ensuring optimal operational efficiency.
