Spain's Escuadrone claims to have developed the world's first drone, equipped with a system for detecting radioactivity, that can be used in the management of nuclear-related emergencies. The Apodaca drone carries probes for detecting alpha, beta and gamma radiation, and the technology has already been successfully used on ground equipment used following the March 2011 Fukushima accident, Escuadrone said.

It also has a system, which can transmit real-time readings and images anywhere in the world using technology and a number of "military security-level" encryption protocols. The drone's powerful engine system, combined with its large wing area, offers flight times up to 90 minutes, the company said.

The drone, alongside fixed detectors installed on the ground, can establish a neural network of sensors which can throughly monitor the most critical areas. The sensors can trace security perimeters for the protection of populated areas and emergency teams on the ground, which is an "invaluable assistance" when making operational decisions during disasters, according to Escuadrone.
