All right, probably no or negligible gammas above 200 keV. >> (c) We don't know if the gammas are emitted isotropically. > > The nickel is a power.

True, but again, this is unknown physics, and the randomly oriented powder is possibly bathing in these EM fields that Rossi possibly uses to control the reaction - this breaks the spherical symmetry. > So they say.

Easy to do with very little shielding. And photons in that range wouldn't have been detected by Villa - this is clearly stated in the abstract. -- Berke Durak
