Question
Chapter 44, Problem 44.58PP
To determine
The positron-electron annihilation occurs on the line 3cm from the center of the line connecting two detectors, the resultant photons be counted in detectors simultaneously from the following:
- (a) No, because the time difference between their arrivals is 100 ms.
- (b) No, because the time difference is 200 ms.
- (c) Yes, because the time difference is 0.1 ns.
- (d) Yes, because the time difference is 0.2 ns.

As we shall find in the chapter on nuclear physics, fast-moving protons are 10 times as effective in causing radiation damage as x-rays of the same energy. Approximately 85% of GCRS are fast-moving protons, and spacecraft traveling in interplanetary space would require thick shielding to attenuate not only the incident cosmic rays, but also the shower of secondary particles created when the cosmic ray particles impacted the shielding material.
