ABSTRACT:
A dosimeter for measuring the intensity of high energy electron, photon, or other particle radiation has ion, electron, and radiation shields about at least respectively sensitive components of the dosimeter. The entire dosimeter, therefore, can be assembled as a unit and portably placed in the radiation to be measured. Ruggedness for this desirable partability is provided by the use in the dosimeter of a pancake ionization chamber which also eliminates the need to calibrate radiologically the dosimeter.
