Radio signals can be interfered with or listened to -- never underestimate the opponent. Computer interfaced radiation detectors, in spite of Tim's claim to the contrary, are pretty cheap and very hard to interfere with.
What about a beam of high intensity ionising radiation aimed at the detector?
If you are paranoid, put the detector in a lead box and you are done. Its not hard to get the lead thick enough that tampering attempts would be noticed very easily. Trying to shield an object from radio signals and still manage to get meaningful numbers out (rather than self generated signal) is a hard problem, but this can be done by a high school student. Perry
