A general purpose high accuracy dosimeter reader (80) for determination of dose, based on comparison of a treated dosimeter (111) with a series of images of pre-treated dosimeter (114). A dosimeter undergoes noticeable changes, such as a color change upon treatment with certain materials, such as toxic gases and processes, such as ionizing radiation and sterilization is pre-treated. The dosimeter is imaged with an imaging device (115) and images of the dosimeter or the changes, are stored in an information storage device (118). In order to determine the dose, the treated dosimeter is imaged and the image is compared with the series of pre-treated images of the dosimeter. The closest match of the treated dosimeter with the pre-treated and pre-imaged dosimeter would indicate the dose. |
