In reply to David Roberson's message of Thu, 4 Apr 2013 19:51:27 -0400 (EDT): Hi, [snip]
Gamma rays are normally absorbed to some extent in normal matter. When such an event occurs, the energy of the gamma mostly goes into ionizing an atom and giving kinetic energy to the freed electron. Presumably the remaining ion shares the momentum with the electron, IOW the ion gets a little kick as well. The energetic electron can then go on to ionize thousands of other atoms. Because it is a charged particle, the electron interacts strongly with other electrons. In this way, the energy of the gamma is thermalized. >That is my fear Jones.
