JK-FJ-G2 X-γPersonal Dosimeter

■Application and characteristic:

X-γpersonal dosimeter an pocket intelligent multifunctional instrument adopting new type single chip is mainly used for monitoring X ray and γray. 1.8”LCD color screen full screening personal dose rate, the cumulative dose, real-time clock, measuring time and alarm threshold and automatic sound-light alarm.The power supply is environmental lithium battery continuously providing power. The main technical parameter meets the national standard and international standard,is widely used in these areas of radiation station, custom, industrial nondestructive inspection, accelerator,nuclear power station, nuclear submarine, radioactive medical treatment,isotope application,medical cobalt treat and monitoring environment around nuclear facilities.
