[QUOTE="James Snover, post: 10210059, member: 67454"] The short answer is that a little antimatter goes a long way. When you are talking about an electron and a positron annihilating, you get a pair of high-energy gamma rays traveling in equal and opposite directions. But the total energy released is still only mc^2, and there isn't a lot of mass in an electron and a positron. And that is all you are dealing with in a PET scan, the occasional electron meeting the occasional positron. So you only get a little high-energy radiation. Now, if you had two gallons of antiwater and water, _then_ you would have a pretty big bang. Jim Snover [/QUOTE]
