Nanodosimeter based on single ion detection

摘要

Abstract A dosimetry method comprising the steps of providing a volume of gas, forming a sensitive volume within the volume of gas such that, on average, a dose of radiation incident on the volume of gas yields a response from the sensitive volume that is substantially equivalent to a response of a biological sample to the dose of radiation, positioning the volume of gas so as to receive the dose of radiation, detecting one or more ions from the sensitive volume resulting from the dose of radiation, and generating data from the one or more detected ions, the data representative of an estimation of the response of the biological sample to the dose of radiation.
