Abstract: A method for determining a level of exposure to radiation utilizes a radiation dosimeter (10) comprising a substrate (12) provided with a radiation sensitive layer or patch (14) having an optical density which varies in accordance with the degree of radiation exposure. In addition, the substrate is provided with optically readable coding (16a, 16b) which identifies one or more encoded mathematical parameters for enabling an automated calculation of dosage from a detected optical density change of the radiation sensitive material. Each dosimeter is provided with a unique identification code encoded in the bar coding on the dosimeter substrate, to enable memory storage of pre-exposure optical densities for multiple dosimeters.

Abstract: A multi-ply radiation dosage indicator (10), and method of manufacture, is disclosed including a first ply (12) having visible indicia (14) thereon and a second ply (16) having a radiation sensitive zone (18) overlying the indicia (14) of the first ply (12). The radiation sensitive zone (18) is capable of changing opacity in response to exposure to a radiation dosage exceeding a predetermined threshold so as to change the visibility of the indicia (14) thereby providing an indication as to whether the indicator (10) has become irradiated. An optical filter ply (26) may be provided overlying the indicia (14), and the indicator (10) also may be provided with a transparent protective outer ply (19). A pressure sensitive adhesive ply (30) having a removable release sheet (32) is employed for attaching the indicator (10) to a substrate.

Abstract: Indicateur de dose de radiation multicouche (10) et procédé de fabrication, comprenant une première couche (12) sur laquelle se trouve une première marque visible (14) et une seconde couche (16) présentant une zone sensible aux radiations (18) recouvrant la marque (14) de la première couche (12). La zone sensible aux radiations (18) peut changer d'opacité en réponse à une exposition à une dose de radiations dépassant un seuil prédéterminé, de manière à changer la visibilité de la marque (14) indiquant ainsi si l'indicateur (10) a été irradié. On peut recouvrir la marque (14) d'une couche de filtre optique (26), et l'indicateur (10) peut également être doté d'une couche extérieure protectrice transparente (19). On utilise une couche d'adhésif autocollant (30) comportant une feuille de libération amovible (32), afin de fixer l'indicateur (10) à un substrat.
