Would a “x ray field” violate Geneva convention? Used to protect a secret base?

Would directed x ray radiation from “radiation machines” placed in towers along the boundary of a secret base like Area 51 be a good defense method?

Have a “x ray area in the 100 feet of the wall to irradiate those who attempted to climb over the wall?

It could be set to cause radiation sickness after 5 minutes of exposure?

X ray tubes could be used along the wall for defense so even those who were able to climb over would have painful radiation sickness?

The zone could surround a base like Area 51 which would cause severe accute radiation sickness before they were able to reach the base?

Would this violate Geneva convention?
