Here are some possible things to look for, ranging from practical to impractical: - Look for isotopic anomalies in the cavity materials. - Look for de-excitation gammas of characteristic energy (but don't assume they must be there). - Look for bremsstrahlung with an endpoint approaching the characteristic energy (in case there's something like internal conversion going on). - Look for excess heat. - Look for thrust, in the event that the neutrinos are being emitted anisotropically. ;) - Put the thing near a neutrino detector that will be able to resolve its location spatially.
