RadPavise | Personal Radiation Detector

  • Description

    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.

Homeland Security/Real-Time Data for Crisis Control
Homeland security has become a top priority in recent years to assure the safety of individuals around the world. Personnel must be prepared to deter and respond to potential exposure to radiation. If asked to perform duties in an environment where radiation may be present, assessing exposure levels is crucial and reporting on a regular basis a necessity. X-Z LAB understands how critical it is that all personnel be protected to reduce or avoid short-term, or acute, exposure to radiation.

State and Federal Agencies/Military
Many state, federal, and military agencies work in environments that monitor radiation programs or environments as well as carry the responsibility for crisis management in the event of an emergency. Ensuring public health, safety, and the integrity of our environment is the primary concern of these government organizations and safety personnel.

First Responders
In any emergency situation, time is of the essence. First responders to any critical scene may not know immediately if the area has been contaminated. Therefore, it is imperative that those first to respond to a crisis carry radiation monitoring dosimeters. First responders may include law enforcement, fire personnel, emergency medical teams, HAZMAT, or even state, federal, or military organizations. X-Z LAB recognizes the special requirements of these agencies. RadPavise | Personal Radiation Detector is specifically tailored to the requirements of any agency.
