RADIZCAN: Gamma Radiation Spectrometry and Mapping System
Simple and fully automated heliborne or UAV-based technologies for advancing radiation monitoring, including enhancing the application of CBRN reconnaissance, environmental mapping, nuclear power plant emergency response and improving long-term monitoring of contaminated areas. Real-time tracking gamma radiation spectra, dose rate values, results of radioisotope composition identification and geographical data of radiation survey maps and areal imaging of radioactive objects.
RadiZcan system includes the gamma spectrometer, detectors, mapping software, pod and everything else is needed to start radiation mapping and monitoring an area.
Heliborne radiation reconnaissance poD
RadiZcan-POD is a heliborne radiation detection system that can: - detect of point radioactive sources. - capable of real-time location, areal imaging and mapping large areas of field contamination, taking into account flight altitude, atmospheric conditions to determine the radiation level of specific areas; and – be able to identify radioactive isotopes to provide a basis for estimating the composition of radioactive contamination by means of energy-selective measurements.
Detectors are installed inside a pod attached to the exterior of a helicopter.
Specifications:
-
The RadiZcan system had to be designed with high vibration resistance and the system can operate reliably in different weather conditions.
-
A portable instrument was designed (Size: 48x40x215cm, Weight: 100,9 kg) that could be quickly mounted on a helicopter.
-
A highly sensitive system that quickly provides real-time measurement data and standardized reporting (ATP45) to emergency responders through LTE/ WiFi/Ethernet/custom radio connectivity.
-
The system can sense and identify the following airborne-detectable isotopes (Co-60, Cs-137, I-131, Ir192) from a safe altitude (50-100m), in a typical incident zone (10-20km2).
Lightweight radiation payload
The RadiZcan-MOB sensor is a lightweight radiation detector designed to be mounted on a UAV, Robot and unmanned ground vehicle for a wide range of applications where radiation detection, measurement, and nuclide identification are needed.
Gamma spectroscopy and mapping software
RadiZcan-SW is a powerful spectroscopy software platform to interpret the signals and identify the isotopes. It is specifically designed to work with RadiZcan detectors but is also can be used with multiple radiation detectors. It displays data from fixed and mobile radiation detection systems.
Multi-screen graphical user interface and architecture consisting of mapping, data analysis and spectroscopy modules on a common platform. This user-friendly and easy-to-use interface fits a wide range of users even with minimal experience.
Features:
-
Real-time view of all sensors.
-
Real mapping data on the (online or offline) map selected by the user.
-
Spectral acquisition from multiple detectors and displaying gamma radiation spectrum data.
-
Simple, non-encrypted flat-file database to store data, and access via standard file transfer protocols (SMB, SFTP) for easy integration to other systems.
-
Output ATP45 (CBRN4 RAD), custom json, and CSV formats.
-
Board and ground-projected dose rate calculation.
RadiZcan system applications
The main beneficiaries of the RadiZcan system are police, CBRN experts, relief workers, disaster managers, crisis managers, researchers, or nuclear workers who can use the system in the following situations:
-
Rapid emergency response monitoring of radiation events, providing real-time data on spread, source and intensity.
-
Aerial monitoring of nuclear installations and radiation hazards
-
Detection of ground contamination and different radiation levels can be identified and mapped.
-
The extent of the contaminated area and its different zones (R1, R2, R3) can be determined by plotting the contaminated area on a map.
-
Detection of point sources: Determination of dose rates significantly different from background radiation.
-
Identification of radioactive isotopes. Energy-selective measurements can be used to determine the isotopes in the field and to determine radiation levels for later dates.
