muscle and 2 cm of bone, as a percent of the initial intensity. (note attenuation coefficient is 1-3.3 for muscle and 15 for bone) it doesnt say but i think we are supposed to use beers law I=I_oe^-ax a is attenuation coefficient and x is distance. problem im having is the value i am getting is super small and incorrect
