AT2533, AT2533/1 Dosimeters

Measurement of ambient dose equivalent rate and ambient dose equivalent of continuous X-ray and gamma radiation in an extremely wide range and under harsh operating conditions, including emergency response.

Measurement of pulsed radiation dose and average dose rate directly at linear accelerators (LINACs) and other pulsed-radiation facilities.

  • High burn-up life, rugged design and robustness of the detection unit
  • Measurement  in liquids at depths up to 40 m
  • Easy to operate in gloves or hazmat suite
  • Instrument-to-PC data exchange over USB or Bluetooth interface (AT2533/1)
  • Additional detector for operator radiation safety
  • Accessories: cable reel, wall brackets, etc.
