Energy spectrum based calculation of the half and the tenth value layers for brachytherapy sources using a semiempirical parametrized mass attenuation coefficient formulism

open access: closedMedical Physics, 2008
As different types of radionuclides (e.g., source) are introduced for clinical use in brachytherapy, the question is raised regarding whether a relatively simple method exists for the derivation of values of the half value layer (HVL) or the tenth value layer (TVL).

TENTH VALUE LAYERS FOR 60Co GAMMA RAYS AND FOR 4, 6, 10, 15, AND 18 MV X RAYS IN CONCRETE FOR BEAMS OF CONE ANGLES BETWEEN 0° AND 14° CALCULATED BY MONTE CARLO SIMULATION

open access: closedHealth Physics, 2007
The calculation of shielding barrier thicknesses for radiation therapy facilities according to the NCRP formalism is based on the use of broad beams (that is, the maximum possible field sizes). However, in practice, treatment fields used in radiation therapy are, on average, less than half the maximum size.
