Advance radiation monitoring: real-time tracking of gamma radiation spectra and dose rate values, as well as identification of radioisotope compositions

Simple and fully automated heliborne or UAV-based technologies advance radiation monitoring. This includes enhancing CBRN reconnaissance, environmental mapping, nuclear power plant emergency responses, and improving long-term monitoring of contaminated areas. They enable real-time tracking of gamma radiation spectra and dose rate values, as well as identification of radioisotope compositions. Geographical data and areal imaging of radiation survey maps and radioactive objects are also integrated.

The RadiZcan system includes a gamma spectrometer, detectors, mapping software, and a pod, comprising everything needed to start radiation mapping and monitoring in an area.

Heliborne radiation reconnaissance pod

The RadiZcan-POD is a heliborne radiation detection system capable of:

  • Detecting point radioactive sources.
  • Real-time location, areal imaging, and mapping of large areas of field contamination.
  • It considers flight altitude and atmospheric conditions to determine the radiation level of specific areas.
  • Identifying radioactive isotopes to estimate the composition of radioactive contamination through energy-selective measurements.
  • Detectors are installed inside a pod attached to the exterior of a helicopter.
  • The RadiZcan system was designed to be highly vibration-resistant, ensuring reliable operation in various weather conditions.
  • A portable instrument (Size: 48x40x215 cm, Weight: 100.9 kg) has been developed, which can be quickly mounted on a helicopter.
  • It is a highly sensitive system that provides real-time measurement data and standardized reporting (ATP45) to emergency responders. This is facilitated through LTE/WiFi/Ethernet/custom radio connectivity.
  • The system can detect and identify the following airborne-detectable isotopes from a safe altitude (50-100m) over a typical incident zone (10-20 km²): Co-60, Cs-137, I-131, and Ir-192.

Lightweight radiation payload

The RadiZcan-MOB sensor is a lightweight radiation detector designed for mounting on UAVs, robots, and unmanned ground vehicles. It serves a broad range of applications requiring radiation detection, measurement, and nuclide identification.

RadiZcan system applications

The main beneficiaries of the RadiZcan system include police, CBRN experts, relief workers, disaster managers, crisis managers, researchers, and nuclear workers. The system can be utilized in the following situations:

  • Rapid emergency response monitoring of radiation events, providing real-time data on the spread, source, and intensity.
  • Aerial monitoring of nuclear installations and radiation hazards.
  • Detection of ground contamination where different radiation levels can be identified and mapped.
  • Determination of the extent of contaminated areas and their different zones (R1, R2, R3), by plotting these areas on a map.
  • Detection of point sources, including determination of dose rates that significantly differ from background radiation.
  • Identification of radioactive isotopes using energy-selective measurements, which aid in determining isotopes in the field and assessing radiation levels for later analysis.
