I didn't see anything describing the container was damaged. That detail is of importance and if it was the shipping container, overpack, or the or the DOT 7A Type A container. As far as a threshold that really can't be answered since there isn't a response, at least public, proposing drone sniffers en masse.. But immediate responses and recovery, it's usually a very significant amount that I've ever seen.i.e. Cesium-137 experimental medical source at 3800 Ci Last one I worked on.
