The reason Black Holes produce X rays at all is because there is
a accretion disk of gas around it that is heated to millions of degrees
just before it falls into the hole, the enormous tidal forces compress
the gas and makes it hot, great stuff for a heat engine.
Another example is the H bomb, a fission trigger produces X rays and
heats some plastic foam to millions of degrees and compresses the fusion
materials. X rays are not neutrinos, lots of things absorb them including air.
