Personal electronic dosimeter

An electronic personal dosimeter is a measuring device designed to assess an individual's exposure to ionizing radiation. Lightweight and easily portable, it is indispensable in environments where radiation risks are present, such as hospitals, nuclear power plants and research laboratories. Its accuracy enables continuous monitoring of exposure, ensuring the safety of exposed workers.

Radiation protection for workers involves effective dosimetric monitoring of their exposure to ionizing radiation during work in controlled or supervised areas.

  • Make it easy to monitor your exposure to ionizing radiation
  • Reinforce the safety of your teams
  • Concentrate on your mission, a supervisor is watching over you!
  • Collect dosimetric data that is reliable, accurate and compliant with regulations.

    Fuji Electric electronic personal dosimeters are reliable, accurate and easy-to-use radiation protection devices that will help you stay safe when working with ionizing radiation. Several models are available so you can find the one that suits your requirements.

    Radiation protection is a serious business. Ionizing radiation can be dangerous to your health if you're not properly protected. That's why it's important to use an electronic personal dosimeter (EPD) when working in controlled or supervised areas. 

    What is dosimetry?

    passive or delayed-reading dosimetry

    Passive or delayed dosimetry

    Passive dosimetry is compulsory for all workers likely to be exposed to ionizing radiation (in supervised or controlled areas).
    Dosimetry data collected over a defined period, ranging from one to three months, can only be read, analyzed and used by an accredited laboratory.

    Several technologies co-exist: radiophotoluminescence (RPL), optically stimulated luminescence (OSL) and thermally stimulated luminescence (TLD).

    active dosimetry

    Active or operational dosimetry

    Operational dosimetry is mandatory for access to controlled areas. Complementary to passive dosimetry, it provides real-time measurement of dose rate and integrated dose equivalent, Hp(10) Hp(0.07) Hp(3).
    A series of alarms integrated into the ambient dosimeter alerts the professional when pre-determined individual dose or dose rate thresholds are reached.

    For the most demanding situations, real-time supervision of the dosimetry received by the wearer is possible thanks to a teletransmission system (teledosimetry).
    Teledosimetry also simplifies the management of your radiation protection department.

    what is a personal electronic dosimeter?

    Unlike passive dosimeters, active dosimeters enableinstantaneous measurement anddisplay of doses and dose rates received. The results of this measurement are used to assess the dose received by the human body during external exposure to ionizing radiation. An individual dosimeter is assigned to a single person. The wearer can consult and monitor his or her level of exposure in the environment in real time.

    This ambient dosimeter is particularly well suited to high-risk areas where the wearer's residence time is limited over a given period.

    It's also an excellent tool foroptimizing your teams'exposure to whole-body radiation as part of radiation protection and operational dosimetry monitoring.

    These personal dosimeters are an essential element in applying the ALARA principles.


    Dosimetric monitoring with personal electronic dosimeters 

    NRF series electronic personal dosimeters are designed to monitor the dosimetry of workers exposed to radiation sources. 

    make it easy to monitor your exposure to radioactivity

    Make it easy to monitor your exposure to radioactivity

    • Enhanced visibility and ease of use: the large, backlit LCD display makes it easy to read dose rate and dose received.
    • Suitable for harsh environments: the electronic personal dosimeter is compact, lightweight, shock-resistant and waterproof (IP65/67), with quick-release fasteners.

    Reinforce the radiological safety of your teams

    • Visual alerts: the colors of the personal dosimeter display and the ultra-bright flashing LEDs (red, orange) vary according to the alarm thresholds and limits you preset.
    • Audible and tactile alerts: a 100-decibel buzzer and vibrating alarm complement visual alerts

    Concentrate on your mission, a supervisor is watching over you!

    focus on your mission a supervisor is watching over you

    • Thanks to active dosimeter telemetry, a supervisor can remotely manage radiological data for teams.
    • Telecommunications functions(WiFi, radio, Bluetooth) are natively integrated into our dosimeter. No need for additional modules.
    • Bluetooth communication also enables the connection of peripheral accessories to enhance team monitoring and safety (alarm reporting wristbands, heart rate monitors, etc.).
    • A built-in accelerometer detects the fall of a lone worker and alerts the supervisor.


    collect dosimetric data

    Collect dosimetric data that is reliable, accurate and compliant with regulations

    • Very high sensitivity and fast response time
    • Wide measuring range :
      1. Gamma, X: energy range from 30 keV to 6 MeV
      2. Neutron: energy range 0.025 eV to 15 MeV
      3. Gamma and Beta: energy range from 500 keV to 2.2 MeV
    • The electronic dosimeter complies with IEC 61526 and ANSI N42.20 standards.
