Abstract
The buildup factorof cylindrical samples (shields) for Brass, Copper & lead (Brass, Cu, Pb (was studied, where buildup factor were calculated with thickness between (0-12) m.f.p. for Co60and Cs137sources with activities (30) & (41) MBq respectively , usingscintillation detector NaI(Tℓ) with (3"×3")volume .The results shows increases of buildup factor for low atomic number(Z) samples where the energy of radiation source was constant, also shows increases of buildup factor with decreases the energy of radiation source. Anempirical equation was obtained using Matlab7 program this equation have agreements with most obtained data for 91%.
