RadPavise | Personal Radiation Detector


RadPavise | Personal Radiation Detector


RadPavise | Personal Radiation Detector by X-Z LAB is an all-digital personal radiation detector covering a wide range of gamma and X-ray radiation.

RadPavise | Personal Radiation Detector is a next-generation all-digital personal radiation detector that combines four functions in one:

  • Dose Equivalent Rate Meter
  • Accumulated Dose Meter
  • Radiation Survey Meter
  • Radiation Source Locator

This pocket-sized, direct-reading PRD accurately detects and measures radiation exposure for workers and responders in potentially hazardous environments.

RadPavise | Personal Radiation Detector 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 real-world applications. The fast response and wide dose rate range maximize the safety of your team. Intuitive navigation allows users to adjust settings in the field.

The unique, high-contrast OLED display provides a clear indication of the wearer’s equivalent dose rate, accumulated dose, and count rate. The search interface can also be used as a survey meter to locate the source of radiation.

RadPavise | Personal Radiation Detector is designed to meet the needs of emergency responders and radiation protection personnel across the United States.
