If a major disaster like Fukushima or Chernobyl ever happens again, the world would know almost straight away, thanks to an array of government and DIY radiation-monitoring programs running globally.

The system, dubbed "DroneRad," can go on either FlyCam's Cypher 6 hexacopter or FlyCam's The NEO octacopter, either of which seem like they're straight out of a cyberpunk novel set in 1998. The existing DroneRad sensor is just for radiation, but additional sensor sets could instead look for airborne chemical weapons like chlorine and nerve as, or for bioweapons like anthrax. There's also an option for the future that can pick up on methane and diesel fumes. FlyCam isn't the first drone to do this. As more and more drones are outfitted with chemical sniffers, the correct response to "does that smell weird?" in the future may just be sending a robot to check.
