As Bob Cook notes, any β+ decay will result in annihilation photons: β+ + β- → 2ɣ + Q (511 keV) Once the positron is produced, it will quickly find an electron nearby, and the matter-antimatter reaction will result in two energetic photons flying off in opposite directions. These photons are energetic enough that they are unlikely to be stopped even by thick metal shielding. If we're talking about watts of XP, e.g., ~ 1e12 reactions per second, and one or more participating reactions produce even a small number of beta+ decays, these photons will be everywhere. I have an active imagination and can imagine all kinds of things that might be thermalizing gammas in certain contexts. But it's hard to see where a theory that predicts significant beta+ decay (e.g., Piantelli's) can go in face of the experimental evidence. I guess we should all keep an open mind. Eric
