Proton beam dosimetry using a TEPC with a 252Cf neutron calibration

A tissue-equivalent proportional counter (TEPC) can measure the linear energy transfer (LET) of incident radiation and directly calculate the equivalent dose to humans in a complicated radiation field. For radiation monitoring, we developed and characterized a TEPC that can simulate a site diameter...

Summary:A tissue-equivalent proportional counter (TEPC) can measure the linear energy transfer (LET) of incident radiation and directly calculate the equivalent dose to humans in a complicated radiation field. For radiation monitoring, we developed and characterized a TEPC that can simulate a site diameter of 2 µ m for micro-dosimetry. It was calibrated with a 252 Cf neutron standard source at the Korea Research Institute of Standards and Science. The channel to LET calibration factor of the TEPC is about 0.72 keV/ µ m-channel. Also, we evaluated the possibility of usage the TEPC as a proton dosimeter.
