X. Gamma and Beta Personal Dose Alarm Devices

X. Individual dose alarm for gamma and betaceremony

Instrument Introduction

X. Gamma and Beta Personal Dose Alarm DevicesMainly used to monitor the radiation intensity of X, gamma, and beta rays in various radioactive workplaces, as well as the amount of radiation absorbed by radioactive personnel in the radioactive environment, to protect the safety of workers. It adopts 16 bit ultra-low power microcontroller technology, and the detector uses compensated dual GM counter tubes, so the instrument has a wide measurement range, good energy response characteristics, high sensitivity, and low power consumption. The dot matrix large screen LCD display provides clear readings and easy operation, ensuring that the instrument is more reliable in radiation environments. Implementing window based detection allows beta rays to enter the detector unobstructed, improving the instrument's response to beta rays. True monitoring of X, gamma, and beta rays has been achieved. It can display both dose rate and cumulative dose simultaneously, and provide alarm indication when exceeding the threshold to ensure the safety of staff.
