8.12 The flux of relativistic cosmic ray muons at the surface of the earth is approximately 250 m-2-!. Use Figure 4.8 to make a rough estimate of their rate of ionization energy loss as they traverse living matter. Hence estimate in grays the annual human body dose of radiation due to cosmic ray muons.
