Proton dosimeter

A dosing mechanism (300) for dosing a proton radiation from a proton dosimeter (200), comprising;

• exposing a depletion zone (122) of a light emitting diode (LED) (120) of the proton dosimeter (200) to the proton radiation, wherein the proton dosimeter (200) comprises:
• the LED (120) that communicates with a light-to-frequency converter (LFC) (124) through a sensitive zone interface of the LED (120) and the LFC (124);
• wherein a plurality of first sensitive zones (122) of the LED (120) and a plurality of second sensitive zones (123) of the LFC (124) are joined together by acrylic glue to form a sensitive zone interface of the LED (120) and the LFC (124);
• and
• wherein the sensitive zone interface of the LED (120) and the LFC (124) is wrapped by a metal foil (111) and a polymer tape (113);
• impinging the proton radiation on the depletion zone (122) of the LED (120) leads to formation of a plurality of non-radiative-recombination-centres (306) in the depletion zone (304) that further reducing the light output (305) of the LED (120);
• converting the light output (305) of the LED (120) to a frequency output (307) by a light-to-frequency converter (LFC) (124);
• and
• calculating a proton fluence based on the frequency output (307) of the LFC (124) of the proton dosimeter (200).

A method of assessing (500) risk factors of a proton radiation comprising;

• detecting and converting (502) a proton radiation output of a light emitting diode (LED) (120) of a proton dosimeter (200) into a frequency output by a light-to-frequency converter (LFC) (124) of the proton dosimeter (200);
• wherein the proton dosimeter (200) comprises the light emitting diode (LED) (120) communicating with the light-to-frequency converter (LFC) (124) through a sensitive zone interface of the LED (120) and the LFC (124);
• wherein a plurality of first sensitive zones (122) of the LED (120) and a plurality of second sensitive zones (123) of the LFC (124) are bonded together by acrylic glue to prepare the sensitive zone interface of the LED (120) and the LFC (124);
• wherein the sensitive zone interface of the LED (120) and the LFC (124) is wrapped with a metal foil (111) and a polymer tape (113);
• calculating (504) proton fluence based on the frequency output of the LFC (124) of the proton dosimeter (200) by the fluence calculator (520);
• converting (506) the proton fluence into a proton dose;
• applying a plurality of application specific dose conversion factors to the proton dose;
• evaluating (510) the proton dose based on a plurality of application specific proton dose conversion factors.
