Abstract
A radiation dosimeter is described which utilizes the conversion of iodide by impinging ultraviolet or other equal or greater energy radiation in the presence of a thiosulfate moderating agent and the subsequent complexing of the iodine producing by a suitable starch to produce a color variation which is indicative of the amount of such radiation received.
