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.

Fuji Electric electronic personal dosimeters are reliable, accurate and easy-to-use 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 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 or operational dosimetry
Active dosimetry is mandatory for access to a controlled area. Complementary to passive dosimetry, it allows real-time measurement of the dose rate and the integrated dose equivalent, Hp(10) Hp(0.07) Hp(3).
A series of alarms built into the dosimeter alerts the worker when predetermined thresholds of individual radiation dose or dose rate are reached.
Real-time supervision of the dosimetry received by the wearer is possible for the most demanding situations thanks to a remote transmission system (teledosimetry).
Teledosimetry software also simplifies the management of your radiation protection.
What is an electronic personal dosimeter (EPD)?
Unlike passive dosimeters, active dosimeters enable instantaneous 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. They are assigned to a single person. The wearer can consult and monitor his or her exposure level in real time.
These dosimeters devices are particularly suitable for high-risk areas where the wearer's stay time is limited.
It is also an excellent tool for optimising the exposure of your teams for their protection.
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 ionizing radiation
Increased visibility: The dosimeter large backlit LCD display allows the dose rate and dose received to be read at a glance.
Adapted to hostile environments: the dosimeter is compact, lightweight, shock resistant and waterproof (IP65/67)A clip on the rear of the personal dosimeter instrument allows the user to wear the instrument on a belt or pocket to represent dose to the whole body
Reinforce the radiological safety of your teams
Visual alerts: the screen's colours and the ultra-bright flashing warning LEDs (red, orange) are variable according to the alarm conditions and thresholds you predefined. Dose, Dose Equivalent Rate are easily seen.
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 also allows the connection of peripheral accessories to increase team monitoring and safety (alarm reporting bracelet, heart rate monitor, etc.)
The built-in accelerometer detects the fall of a lone worker and alerts the supervisor
Collect reliable, accurate and regulatory-compliant dosimetry data
Very high sensitivity and fast response time
Wide sensitive measurement range:
Gamma, X-ray radiation : energy range from 30 keV to 6 MeV
Neutron: energy range 0.025 eV to 15 MeV
Both Gamma and Beta: energy range 500 keV to 2.2 MeV
The dosimeter complies with IEC 61526 and ANSI N42.20 standards. • Data including dose rate measure histories and alarm events are stored in a memory and can be downloaded for personnel dose management through PC software and a reader
Applications for electronic personal dosimeter
The electronic personal dosimeter is designed for the regulatory protection of workers exposed to ionising radiation.
