UAV radiation mapping drone

Complete UAV radiation mapping drone system

The Kromek UAV radiation mapping drone offers an accurate, affordable and versatile low-altitude aerial radiation detection vehicle which is an out of the box solution for anyone that needs to examine an area or patrol a location for radiation levels or contamination. The system gives you real-time location, measurement and mapping of radioactivity with isotope identification.

UAV radiation and mapping drone: what do you get

1. Aerial unmanned drone

A Small Unmanned Aircraft System (SUAS) with an all up weight less than 7.0 kg. This low total mass, coupled with the in-built redundancy of the aerial system represents a low risk of structural damage to buildings and the environment during its operation. This is in line with UK CAA guidelines.
The drone has a number of supporting sensor: positioning fixing (Latitude and Longitude) by multi GNSS (GPS and Glonass), number of satellites and height above mean sea level (AMSL); temperature, humidity and pressure; embedded real-time clock providing time/date fix (GSM and GNSS available as back up); laser ranging to determine height above the surface being monitored to ~1mm over 100m.

2. Radiation detector unit and payload bay

Sensors and micro-controller including battery all enclosed within one container mounted on a universal gimbal. Multiple gamma spectrometers can be connected to one unit and work simultaneously. The unit is designed for:

  • Kromek GR1 10 x 10 x 10 mm CZT based detector. Energy resolution @ 662 keV (21°C operation) <2.5% FWHM. Energy Range 30 keV – 3.0 MeV
  • Kromek SIGMA 50 25.4 x 25.4 x 25.4 mm CsI(Tl) scintillation radiation detector. Energy resolution @ 662 keV (21°C operation) <7.2% FWHM. Energy Range 50 keV – 1.5 MeV

3. Gamma spectroscopy and mapping software

10Hz snapshot rate of units data providing high resolution at speed, count per second (CPS) and spectral data transmitted simultaneously every 1 second.
Data in mapping application includes CPS over time; energy spectrum; CPS and location; dose estimation; isotope characterisation.

4. Flight training and set-up

The UAV training course covers learning to fly, mission planning, use of software and other operational concepts.
