Electronic Personal Dosimeter

An electronic personal dosimeter, a type of radiation 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.

  • Facilitate the monitoring of your radiation exposure to ionising radiation
  • Increase the safety of your teams
  • Focus on your mission, a supervisor is watching over you!
  • Collect reliable measure, accurate dosimetry data that complies with the 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 matter. 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 reading dosimetry

    Radiation dosimeters, including both passive and active types, are essential tools for measuring and monitoring radiation exposure. Dosimetry is the calculation and assessment of the radiation dose received by the human body. It is a critical aspect of radiation protection and safety, particularly for workers in environments where radiation exposure is a concern.
    Passive dosimetry is mandatory for all workers who may be exposed to ionising radiation (in supervised or controlled areas).
    The reading, analysis and use of dosimetry data collected during a defined period, ranging from one to three months, is only possible 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 an electronic personal dosimeter (EPD)?

    what is a personal electronic dosimeter?

    Unlike passive dosimeters, active dosimeters enableinstantaneous measurement anddisplay of doses received and dose rates. The results of this measurement are used to assess the dose received by the human body during external exposure to ionizing radiation. These dosimeters measure personal dose equivalent, providing real-time data on the dose received by the wearer. 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 is also an excellent tool for optimising the exposure of your teams for their protection.

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

    Dosimetric monitoring with electronic personal dosimeters 

    The NRF50 series of electronic personal dosimeters are designed for the dosimetry and personal radiation monitoring of workers exposed to ionising radiation 

    make it easy to monitor your exposure to radioactivity

    Make it easy to monitor your exposure to ionizing radiation

    • Increased visibility: The dosimeter's large backlit LCD display allows the dose rate, dose received, and personal dose equivalent to be read at a glance.
    • 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 alarm and tactile alerts: a 100-decibel buzzer and a vibration complete the visual alarm to alert the wearer

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

    • Thanks to telemetry, a supervisor can remotely manage the radiological data of teams
    • Telecommunications functions (Wifi, radio, Bluetooth®) are natively integrated into our dosimeters. No need for an additional module.
      • IR is included for data transmission to PC with a reader
    • 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.
