Measurement of absorbed dose, quality factor, and dose equivalent in water phantom outside of the irradiation field in passive carbon‐ion and proton radiotherapies

Abstract

The authors experimentally obtained absorbed doses, dose-averaged quality factors, and dose equivalents in water phantom outside of the irradiation field in passive carbon-ion and proton radiotherapies with TEPC. These data are very useful for estimating the risk of secondary cancer after receiving passive radiotherapies and for verifying Monte Carlo calculations.
