title: Infinite thickness in autoradiographs of iodine-125.
abstract: Infinite thickness for iodine-125 in autoradiographs was measured by autoradiography using four types of nuclear emulsion. Using Ilford K5, Kodak AR 10 and Hyperfilm-3H, a value of 20 microns was obtained. Using Hyperfilm Betamax, infinite thickness was greater than 60 microns. The results are discussed in relation to the types of radiation emitted as a result of iodine-125 decay and in relation to published image spread data for this radioisotope.
