Here is the cite regarding the drones and the sensors. You will find video clips etc as well, they arent too hard to find. According to the post the drones are 'HPGe nuclear detector drones', and do indeed attempt to sense gamma frequency EM radiation. As I mentioned earlier, its not the only measurable and detectable by-product of radioactive material, but perhaps its the easiest to pick up.
