title: Dose distributions in regions containing beta sources: small scale nonuniformities.
abstract: An analytic model for the calculation of dose in regions containing slightly nonuniform distributions of beta sources, and a solution for the dose distribution in an infinite, homogeneous medium with a uniform, monoenergetic source distribution and a sinusoidal perturbation of the source are presented.
