dc.description.abstractAn extrapolation chamber is a parallel-plate ionization chamber with an adjustable air-cavity volume through the variation of the distance between the collecting electrode and the entrance foil. The measured ionization currents can be obtained for different chamber depths, and extrapolated towards zero chamber depth. In this work, results of Monte Carlo simulations using MCNP5 and MCNPX codes are reported for 90Sr/90Y and 85Kr beta radiation spectra incident on a 23392 model PTW extrapolation chamber. The results for transmission factor, absorbed dose rate in tissue as well as the chamber response as a function of the chamber depth are in good agreement with experimental data.pt_BR
