It has incredible penetrative power, and would be immediately fatal to biological life. I have no doubt that’s what they use to kill planetary ecosystems. They probably employ multiple devices for full coverage.” Thor called up a particle diagram. “Damage to electronics comes not from the gamma radiation per se, but from the secondary ionization induced in the structure. My proposed solution is two layers of depleted uranium alternating with two layers of electrostatic
