Semi-empirical relationship for the energy absorption buildup factor in some biological samples
Semi-empirical relationship for the energy absorption buildup factor in some biological samples
Energy absorption buildup factors in the energy range of 0.2 MeV to 2 MeV
using a geometric progression fitting approximation in some selected
essential amino acids, fatty acids and carbohydrate molecules have been
obtained. A semi empirical relation-ship describing energy absorption buildup
factors as a function of penetration depth, Compton scattering and energy
absorption cross-section is used. This semi empirical method was defined in
an earlier work on water and soft tissue by one of the present authors. We
used this method for the calculating energy absorption buildup factor in
biological samples. The results are compared with the energy absorption
buildup factors data of the geometric progression fitting method. Good
agreement between semi empirical and geometric progression fitting methods
has been observed, so that average deviation is less than 2 % for all
samples
