TEPC Measurements and Monte Carlo Calculations for Evaluating Ambient Dose Equivalent Response in Mixed Radiation Fields Around the Shielded Area of a Carbon Ion Accelerator

The tissue equivalent proportional counter is a versatile instrument used to determine the absorbed dose and the quality of an unknown radiation field, but it does not directly measure the operational quantity ambient dose equivalent H*(10). In this paper, simulated and measured values of H*(10) are compared, and some corrections are applied in order to give a reliable estimate of H*(10) in a complex radiation field generated by high-energy carbon ions.
