RadTarge-H Electronic Personal Dosimeter


The RadTarge-H Electronic Personal Dosimeter is a high-performance all-digital electronic personal dosimeter that detects gamma and X-ray radiation, offering full-range reading and alarm response in less than two seconds

RadTarge-H | Electronic Personal Dosimeter is a next-generation all-digital electronic personal dosimeter that combines four functions in one:

  • Dose Equivalent Rate Meter
  • Accumulated Dose Meter
  • Active Self-Reading Dose Meter
  • Active Self-Alarming Dose Meter

This pager-like, direct-reading EPD accurately detects and measures radiation exposure for workers and responders in potentially hazardous environments.

RadTarge-H | Electronic Personal Dosimeter uses a YSO scintillation detector combined with a state-of-the-art silicon photomultiplier (YSO+SiPM) and multi-voltage threshold (MVT) algorithm to detect a wide range of radiation doses.

Proportional, real-time detection and measurement provide meaningful readouts that focus on the awareness and safety of the user during critical times. The fast response and wide dose rate range maximize the safety of your team. Intuitive, menu-driven navigation allows users to adjust settings in the field.

A blue acrylic tamper-proof label prevents users from opening the instrument, thus ensuring operational integrity for compliance and liability concerns.

RadTarge-H | Electronic Personal Dosimeter is designed to process routine personnel dosimetry on which occupational dose of records are based.
