Instrument Overview

The YD-100D personal dosimeter alarm is primarily used for radiation protection monitoring of X-rays, gamma rays, and hard beta rays. The instrument can display the dose rate and personal cumulative dose in real-time; it is suitable for nuclear power plants, industrial X-ray and gamma non-destructive testing, radiation therapy, gamma irradiation, environmental monitoring around nuclear facilities, and other fields to provide timely alarm indications, ensuring the safety of personnel. The instrument adopts microcontroller technology, featuring a wide measurement range, excellent energy response characteristics, and low power consumption.
