# Start with RAD payload

Perform fast and accurate radiation surveys of indoor spaces with the Elios 3 RAD Payload, powered by
\
Mirion Technologies. It provides in-flight and post-flight radiation readings, localization, and
\
reporting, plus a detachable sensor for easy swapping with existing units.

In this video, you will see how to mount the RAD sensors and how to use it. The last part of the video covers the limitation of the Rad sensor.
