Perhaps about 3 radio controls would be safer, and a little logic, so they all must be transmitting in order for it to go off (obviously different freq's!) - or a decoder circuit so radio signals are sent in a stange pattern before it is set off, perhaps using a microcontroller of some sort.
By far the easiest and safest method would be a long wire though ;-)
