An oncology clinic processes shielding calculations for radioprotection in an X-ray therapy room.
Define the term half-value thickness of a shielding material.
The half-value thickness of aluminum for a diagnostic X-ray beam is 2.4×10−2 m2.4 \times 10^{-2}\text{ m}2.4×10−2 m.
Calculate the mass attenuation coefficient of aluminum for this beam. State an appropriate unit for your answer.
Density of aluminum = 2.7×103 kg m−32.7 \times 10^3\text{ kg m}^{-3}2.7×103 kg m−3.
