I considered going over with my new venture of Aerial Videography (HD camera's mounted to large helicopter's) to do some surveilence of the nuclear reactors as there semed to be very little in the way of anything getting very close!
After abit of reading though, i found out that the radiation pretty much fries the electronics in anything we use. The full size helicopter's dropping water over the reactors apparently have large lead plates underneath to reduce the radiation efects with the aircrafts electronics.
