FXG mass attenuation coefficient evaluation for radiotherapy routine

Journal of Physics: Conference Series, 2004
The knowledge of a radioactive beam energy or quality is important in radiotherapy once it is correlated with the type, size, and localization of the tumor. One indicative of the radiation quality is the half-value-layer (HVL), the material thickness which reduces the beam intensity to half.
