New type X JB4020, gamma radiation personal dose equivalent (rate) monitor

brief introduction

JB4020 X, gamma radiation individual dose equivalent (rate) monitor (abbreviation: personal dosimeter) X, gamma ray radiation is mainly used for monitoring various radioactive workplace, protect the safety of staff; the instrument can also measure the dose rate and cumulative dose. It adopts a new type of single chip microcomputer technology with strong function, the detector is a compensated GM counter tube, so the instrument has a wide measurement range, good energy response characteristics, with overload indication and protection function.

Instrument characteristics

L high sensitivity, can be measured at the end of the environment

L dose rate and cumulative dose display

L using single chip technology, more functions, small size

L operation is simple, easy to use

L preset alarm threshold

L power supply battery under voltage indication

L dose rate, cumulative dose alarm function

Cumulative dose can be stored for long time after power failure of L

L has the function of real-time clock, the normal operation of the clock after shutdown

Main technical index

L dose equivalent rate: (0.1 ~ 200) Sv/h

L: 0 Sv~99.99 mSv dose equivalent

L radiation energy: 50keV ~ 1.5MeV

L energy response error: less than 30% (relative to 137Cs)

L relative intrinsic error: 15%

L measurement repeatability: 5% (single measurement relative standard deviation)

L protection alarm response time: less than 5 seconds

L display: LCD display, dose rate and cumulative dose (Sv/h) (Sv) - international standard unit

L power consumption: 1 Section 5 battery can work continuously for 500 hours (under the background of the state)
