Description
The functions Λ(r, z), G(r, θ), g(r) and F(r, θ) were calculated for Amersham model CDCS-M-type 137Cs source by means of Monte Carlo simulation using the algorithm PENELOPE. These functions are required to verify and/or to feed planning systems or directly as entrance data for the manual planning of the distribution of absorbed dose according with the recommendations of the TG 43, [1]. The values of the constant Λ (r, Z) were determined as the quotient of absorbed dose rate distribution in water and air kerma strength in 'free air' Sk. The values obtained for Λ (r, Z) differ up to 3% of those reported in the literature, being very sensitive to the cutoff energy for the electrons in the interface of the source's encapsulated and water
