<p>A dosimeter (10) that includes tissue equivalent bubbles of plastic defining volumes of gas to be ionized by radiation. One or more integrated circuits (ICs) are disposed below the volumes of gas and a collecting electrode on the IC is in direct contact with the gas. Circuitry (18) for generating an electric field within the volume of gas moves the ions therein to the collecting electrode. The collecting electrode is part of an amplifying circuit (20) disposed within the IC. The output from the amplifier (20) is representative of the collected ions and therefore representative of the radiation. The signal from the amplifier (20) is sent to an interface (14) which conditions, buffers and stores the signal. The radiation dose and dose rate are computed in the interface at (30). A communications section (36) transfers that data from the dosimeter upon receipt of an externally generated data transfer command. A separate calibration (34) and display unit (31) calibrates the dosimeter (10) by controlling the conditioning of the signal.</p> |
