“…In the case of contamination with gamma-emitting radionuclides, spectrometric gamma detectors that can both identify radionuclides and deduce the dose rate, such as scintillators or semiconductor detectors, have already been mounted on UASs and are commercially available. The characterization of the response of spectrometric gamma detectors mounted on UASs has been carried out in different works, such as those in the framework of the European project "Preparedness" (Preparedness: Metrology for mobile detection of ionising radiation following a nuclear or radiological incident (http: //www.preparedness-empir.eu/ (accessed on 31 August 2023)) [3,4].…”

The protection of first responders from radioactive contamination with alpha emitters that may result from a radiological accident is of great complexity due to the short range of alpha particles in the air of a few centimeters. To overcome this issue, for the first time, a system mounted on a UAS for the near-real-time remote measurement of alpha particles has been developed, tested, and calibrated. The new system, based on an optical system adapted to be installed on a UAS in order to measure the UV-C fluorescence emitted by alpha particles in the air, has been tested and calibrated, carried out in the laboratory and in field experiments using UV-C LEDs and 241Am sources. In experimental flights, the probability of detecting a point source was determined to be approximately 60%. In the case of a surface extended source, a detection efficiency per unit surface activity of 10 counts per second per MBq cm−2 was calculated. A background count rate of UV-C of around 26 ± 28 s−1 for an integration time of 0.1 s was measured during flights, which led to a decision threshold surface activity of 5 MBq cm−2.

An airborne γ-ray spectrometry system that can be installed on an unmanned aerial vehicle (UAV) was designed to satisfy the requirements of radioactive mineral exploration and environmental radiation monitoring. The system consists of an airborne measurement device and a ground control platform. The airborne measurement device includes a γ-ray spectrum survey instrument, the main controller, data and graph transmission module. The ground control platform integrates the data and graph transmission module, industrial computer, energy spectrum analysis and processing software. Field flight tests showed that the data collected by the system were stable and reliable, and the survey results were consistent with existing data. The designed system can be applied to small-scale radioactive geological surveys, environmental surveys, and radioactive pollution monitoring.

“…The use of drones in these areas makes it possible to reduce the risk to human life, to control the situation very quickly and accurately 1 . Drones are now commonly being used for environmental radiation monitoring and radiological mapping following a nuclear or radiological emergency, such as at Fukushima in Japan and the Chernobyl nuclear power plant in Ukraine [4][5][6][7][8] . The main requirements on radiation monitoring devices used in drone technology are low power consumption, light mass, humidity resistance, resistance to vibration and shock, and so on 8 .…”

This paper is devoted to gamma-ray detection performance of the newly developed MAPD-3NM-II type SiPM sensor array (4x4) with LaBr3(Ce) scintillator. The gamma-ray spectra of various sources have been measured in the energy range from 26 keV up to 1332 keV. The newly developed array based on MAPD-3NM-II sensors proved ∼22 % enhancement in energy resolution in comparison to the former MAPD-3NM-I based array. The energy resolution of 662 keV gamma-rays measured by MAPD-3NM-II was 3.3 % while clearly surpassing 4.25 % resolution of MAPD-3NM-I predecessor. The enhancement is related to the high PDE of the new MAPD-3NM-II. Obtained results show that the new MAPD-3NM-II demonstrated good energy resolution and linearity in the studied energy region. The energy resolution of the new detector developed based on MAPD-3NM-II was better than all previous products of MAPD.
