The Flyability Elios 3 RAD Package combines the Elios 3 indoor inspection drone with a radiation detection and localization payload developed with Mirion Technologies. The system is designed to survey radiological conditions in indoor spaces while keeping personnel outside the inspected area. It provides in-flight radiation measurements together with Elios 3 visual and mapping data to support radiation surveying, hot spot identification, dose-field assessment, and inspection planning in radiological environments.
During flight, operators can monitor current dose rate, cumulative flight dose, maximum measurement, measurement history, and sensor saturation. Radiation measurements are recorded with visual and mapping information for post-flight analysis. In post-processing, the drone trajectory can be colorized according to instantaneous dose-rate readings to help locate radiation sources on a 3D asset map. These capabilities support radiological surveying, dose planning, intervention planning, and radiation hot spot localization while reducing the need for personnel to enter the surveyed area.
Remote radiation detection and localization
The Elios 3 RAD Payload was developed in partnership with Mirion Technologies for remote radiation surveying of indoor spaces. The payload combines radiation measurements with Elios 3 flight, visual, and mapping data to help operators identify, locate, and monitor radiological dose fields without requiring personnel to enter the surveyed area.
In-Flight Radiation Readings
The Elios 3 RAD Payload provides in-flight radiation information including current dose rate, cumulative dose for the flight, maximum measurement for the flight, measurement history, and sensor saturation. These measurements allow operators to monitor radiation conditions and identify areas with elevated radiation levels during the mission.
Radiation Hot Spot Localization
Radiation measurements captured during flight are recorded together with visual and mapping information. During post-processing, the drone's trajectory is colorized according to instantaneous dose-rate readings, helping operators locate radiation sources on a 3D map of the inspected asset.
Flyability notes that trajectory colorization is indicative and may overestimate or underestimate dose rates because of drone speed and sensor convergence time. For an accurate measurement, the drone must remain at a location until the sensor fully converges, with the process repeated for each point of interest.
Powered by Mirion Technologies
Flyability partnered with Mirion Technologies to develop the Elios 3 RAD Payload. The system uses Mirion radiation sensing technology to support radiation measurements across dose-rate conditions ranging from µSv/h to Sv/h.
Detachable and Swappable Sensor
The Elios 3 RAD Payload is compatible with RDS-32 WR sensors, allowing compatible sensors to be exchanged as needed to support maintenance and calibration requirements. Flyability specifies that RDS-32 WR sensors used with Elios 3 must be configured according to Flyability recommendations and applicable local regulations to maintain data quality and reliability.

Identify, Locate, and Monitor Radiological Dose Fields
The Elios 3 RAD Payload can be deployed from outside the surveyed area to collect radiation measurements inside indoor environments. Operators can use the collected readings to evaluate radiological conditions and identify areas requiring additional investigation.

Support Dose Planning
Radiation measurements collected with the Elios 3 RAD Payload can support intervention planning by helping teams estimate anticipated worker dose and identify radiation hot spots before personnel enter the surveyed area. This information can be used when planning work intended to minimize personnel exposure.

Evaluate Avoided Personnel Exposure
The Elios 3 RAD Payload records cumulative dose measurements that can be used to evaluate how much personnel radiation exposure was avoided by performing the radiation survey remotely.
