This is supposed to be written for a layman, or so the introduction says, but it pretty much made my eyes cross with the technical stuff. I mean, I can follow the explanation of how gamma rays free electrons which then cause damage to neighbouring atoms, and then the energy of all this and the ‘healing’ atoms makes the other element glow with heat, but I have a limited amount of tolerance for pages on pages explaining the difficulty in getting a direction for the gamma ray bursts from that.
Just, generally, too much information for me. I suspect that someone more interested in astrophysics would enjoy it more, but mine is a casual interest. I’m most interested in gamma rays when Bruce Banner and Tony Stark are studying them to locate an object of immense power in the hands of most emphatically the wrong person.
(Or if there was a description of the effect of gamma rays on DNA. That too would’ve got my attention as surely as a giant green ragemonster.)
