Brachytherapy planning is performed based on the AAPM TG-43U1 protocol. The protocol is normalized in the air-kerma strength. The absorbed dose of air and the air-kerma are regarded as the same in a state where the charged particle equilibrium is established. However both dose not match within some distances from the radiation source. we investigate the air and air-kerma strength using EGS5 simulations. Determinations of the air-kerma strength are methods of using the mass energy-transfer coefficient and integrating the electron kinetic energy directly. These two results we were compared.
