| 1. A method for monitoring radiation exposure for a patient undergoing a medical procedure, comprising:
inserting a single-use dosimeter into a patient, wherein the at least one dosimeter comprises at least one radiation sensor
circuit with a MOSFET and electronic memory that holds calibration data for the MOSFET;
exposing the patient to radiation in a medical procedure during a treatment session;
transmitting data from the dosimeter to a dose-reader device after the exposing step, the transmitting data comprising the
calibration data and data associated with a change in an operational parameter in the MOSFET of the dosimeter radiation sensor
circuit;
removing the dosimeter from the patient after the exposing step during or proximate in time to the treatment session; and
determining a radiation dose received by the patient during the exposing step based on the change in the operational parameter
of the MOSFET and the calibration data.
