Abstract

PURPOSE:To measure a does as a variable-area does by a construction wherein a dosimeter consits of a high voltage electrode and a current collecting electrode being attached to a 3-layer plastic film. CONSTITUTION:A 3-layer plastic film 2-4 is spread within a ring-shaped frame 1 and a space is provided between the layers. A high voltage electrode 5 in the form of an aluminum foil is made to stick to either surface of the middle layer of the plastic film 3. A current collecting electrode 7 in the form of an aluminum foil is attached to the almost whole inside surface of the external layer of the plastic film 2, while a current electrode 8 in the form of a small piece of aluminun foil is attached to the inside surface in the center of the other external layer of the plastic film 4. A protective ring 9 in the form of aluminum foil is attached to the whole inside surface of the external layer of the plastic film 4 through a small gap t on the external perimeter of a current collecting electrode 8.
