Description

The Atomtex AT1121 and AT1123 are designed to measure continuous, short-term, and pulsed X-ray and gamma radiation within wide ranges of ambient dose equivalent rate and energy. Additional functions: detecting soft and hard gamma radiation sources, beta radiation sources, short-term and pulsed radiation with exposure time assessment, and detecting moving sources as well. The Atomtex AT1121 and AT1123 automatically logs maximum dose rate value for the time of operation and are able to store up to 999 measurement results in non-volatile memory for a long time and to subsequently transfer this data to PC. Dosimeters have a self-testing mode which is activated after switching-on as well as during dosimeter operation. External control panel and external alarm unit can be attached to dosimeters for remote monitoring application.

Features:

  • Tissue-equivalent detector – scintillation plastic with heavy metal additive
  • Measurement of short-term (from 30 ms – AT1121) and impulse (from 10 ns AT1123) radiation
  • Exposure time assessment
  • Large dedicated digital/analogue LCD screen with backlighting
  • Integrated system for LED measurement path stabilization
  • Sound and visual alarm in case threshold level is exceeded
  • External control panel can be used for remote measurement
  • Fixed installation is possible with alarm dosimeter functionality and remote control from the distance of up to 25 m
