Abstract
A dosimeter analysis system provides the capability to easily handle the radiochromic pieces of film which are commonly employed as dosimeters and make an accurate analysis of the amount of radiation received in an irradiation process. The dosimeter is constructed through use of one or more layers of a material such as paper, cardboard or non-woven material between which a piece of radiochromic film may be positioned. Through at least one of the layers, an aperture is formed which provides for the direct viewing of the radiochromic film. This dosimeter card may then be placed in a dosimeter card holder and placed in an analysis device such as a spectrophotometer. Also included on the dosimeter card may be a unique marking which provides a reference to unique information pertaining to the piece of radiochromic film employed in the dosimeter card. Further, a system may be employed to access this information when the dosimeter card is being scanned and further employ this information to provide a more accurate or complete reading of the radiation dosage received by the dosimeter card.
