The POI route following is on-board control, no radio signal received to be jammed or scrambled.
The software also blends accelerometers and GPS-based Z position information that lets you set an altitude. If you watch the earlier ones, he walks over and gives the thing a shove and it returns to the original set position immediately. For the lighter payloads, vertical flight is more than 4.5 m/s, but updrafts are not a problem as lift will be reduced. In GPS guide mode, the position is maintained within 5M, but will use the three accelerometers, the attitude is monitored at 1000 Hz to maximize stability of the platform, and then you have the isolated pan and tilt mount that always keeps the aperture pointed at the position target, regardless of vertical or horizontal position. You could program a 300 ft pirouette around a point, and the camera will always stay pointed at the center.
Operating temps are up to 104 F for that model, so you can't fly directly over the exposed core, but climb to 100 meters with a cross-wind component, and you would not even be in the thermal plume.
I always thought that transitive effects on unshielded processors and circuits start becoming noticeable at around 800 mS of gamma and 500 Ms for neutron. For emergency use like this, I would say beta and alpha are not present in concentrated dosage in the air to worry about. Just spray the thing down when it flys home.
You would have to fly very close and stay longer than the batteries would allow for the circuits to degrade so badly that you would not be able to recover it.
But c'mon, at $5k a pop, who cares of you fly one right into the reactor? You aren't going to make the problem any worse, right? You just know to increase the radius around the plant and shorten the dwell time.
At least people would be able to get some more info than what seems to be available now.
