Question

B4. A bone sample has a density p = 1.2x10³ kg/m³, a molar mass m = 217 g/mol and an
interaction cross section per atom o = 6.0x10-22 cm². Determine the linear attenuation
coefficient µ (in cm-¹) and the half value layer (in cm). Assume there is no scattering when
the radiation interacts with the bone sample.
Express the values to 3 significant figures, if necessary.
