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. The NRF series includes models for X-ray, gamma, neutron, and beta measurement.

Radiation protection is a serious matter. Ionizing radiation can be hazardous to your health if you are not properly protected. That is why it is important to use a electronic personal dosimeter (EPD) when working in controlled or monitored areas.

What is dosimetry?

Passive dosimeter

Passive dosimeter 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. Data from EPDs can be logged and downloaded for compliance documentation.

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

Active and operational dosimetry

Active 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. The cumulative dose is displayed in microsieverts or millisieverts.

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 dosimeter and electronic dosimeter?

Unlike passive dosimeters, active dosimeters enable instantaneous measurement and display 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 personal 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 for optimizing your teams' exposure to whole-body radiation as part of radiation protection and operational dosimetry monitoring.

These personal dosimeters are an essential component of applying the ALARA principles.

Dosimetric monitoring with electronic personal dosimeters

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
