Smart Device to Monitor Radiation Exposure Among Nuclear Plant Workers
Doza Research and Production Enterprise, based in Zelenograd, has announced the upcoming release of DOZA-TLD-auto, an automated thermoluminescent dosimetry system designed to measure individual radiation doses for people working in hazardous areas. The device runs on a Russian operating system.
Thermoluminescent dosimetry remains the gold standard for accurately tracking accumulated doses of ionizing radiation. Personnel at nuclear power plants, medical centers and industrial facilities wear specialized detectors that record their radiation exposure. Heating these devices makes it possible to measure the dose they have accumulated.
The new system fully automates this process. It reads data from personal dosimeters and transfers the results to dose-tracking software. It measures dose equivalents for photon, beta and neutron radiation, including in mixed radiation fields.
The system automatically reads identification numbers, calculates accumulated doses and generates reports.
Domestic Software and Seamless Integration
A key feature of the system is its use of an entirely domestic software stack. The device runs on Astra Linux, a Russian operating system. This supports information security and meets regulators’ stringent requirements for critical information infrastructure.
The software can also be configured to meet the needs of individual facilities and integrates seamlessly with automated individual dosimetry monitoring systems (ASIDK). Dose data are stored in a centralized company database, creating electronic radiation safety records for each employee.
Operators can see the devices on a map and monitor their operating status in real time. Algorithms automatically flag defective detectors, filtering out units that are damaged or have produced invalid readings.
Built-In Irradiator and Hardware Stability
To ensure measurement accuracy, Doza’s engineers have integrated an in-house calibration module into the system’s housing. The built-in irradiator supports checks using reference sources based on strontium-90, yttrium-90 and cesium-137. Operators can therefore check the reader’s sensitivity regularly without sending equipment to outside laboratories or using additional equipment.
The developers have also included a function for monitoring the system’s stability without using radioactive sources. As a result, the system can run self-diagnostics. The system is also certified to safety class 3N under NP-001-15 regulations. This allows it to be used at all nuclear facilities, including reactor buildings and radioactive waste storage facilities.
Export Prospects
The Russian manufacturer’s automated individual dosimetry monitoring systems have already demonstrated their reliability on international projects. For example, Doza supplies equipment for Türkiye’s Akkuyu Nuclear Power Plant, which is under construction. The company has already manufactured more than 10,000 devices for the customer, including large-scale automated individual dosimetry monitoring systems and systems for issuing authorized devices.
Alongside its stationary DOZA-TLD-auto system, the company makes new portable devices for rapid radiation monitoring, including the DKS-11D and DKG-11D, which display current radiation levels on screen instantly; the compact DKG-09D Chizh; and the versatile MKS-17D Zyablik dosimeter-radiometer, which supports wireless communications.
Doza has been developing radiation safety technologies since 1991. Its equipment is now used at facilities in more than 50 countries. By moving to automated systems built with domestically produced electronic components, Russia is strengthening its position in the global dosimetry equipment industry.
