Product Profile:
Belarus ATOMTEX AT1121 x, gamma radiation detector can measure environmental dose equivalent and environmental dose rate equivalent of X-ray and gamma-ray
The instrument is simple to operate and easy to carry.
The main function of the detector is to detect the pulse radiation from 10 ns of pulse time.
Short-term radiation with pulse duration from 30 ms and continuous X-ray and gamma radiation with wide range energy and environmental dose rate equivalent
The detector can detect various soft and hard gamma and beta radiation sources.
Pulse and Short-term Radiation with Exposure Time Assessment and Radiation Detection Device for Moving
Any limit within the range can be set by using the keyboard on the instrument.
Automatic storage of maximum dose rate
It can store 100 measurements for a long time in memory and transmit data to a computer at the rate of 300 to 1200 baud.
The tester can have self-checking mode both at turn-on and start-up and during the whole operation, and no reference source is needed because of the stability measurement method of LED.
