Russia has invented dosimeters based on "luminous" tablets

Scientists at the specialized Scientific Research Institute of Instrument Engineering (SNIIP, part of the Rosatom State Corporation) have developed new personal devices designed to measure the accumulated dose of radiation.

"The development is a device that every employee carries with him while staying at a nuclear facility. Its main element is phosphor detectors in the form of tablets, created on the basis of magnesium and boron compounds," Andrei Gordeev, chief designer of SNIP, told Izvestia.

According to him, the pill detectors perform the function of the equivalent of human tissue in the accumulation of radiation dose. At the same time, they have the property of glowing when heated — the brighter the higher the accumulated dose. The photon streams are then captured by photomultiplier sensors, and the electronics convert the received data into instrument readings.

According to Gordeev, the advantage of the development is that the annealing of the detector tablets is carried out in "room" conditions. In contrast, foreign analogues require an inert atmosphere, which is maintained by pumping nitrogen, a gas that almost does not react with other substances. However, this requires special equipment, which complicates and increases the cost of the process.
