The major portion of the sin dose produced by a pinpoint source of radioactivity (hot particle) is caused by beta radiation. This article reviews the key parameters that must be defined in order to perform a beta skin dose assessment. Three empirical dose distribution equations derived by Loevinger are presented--those for a point source, and infinite plane source, and a finite circular plane source--and the reciprocal dose theorem is described. A computer method is derived for calculating beta skin dose to a target area by dividing the area into many subintervals and using the point source equation to calculate the dose rate for each subinterval. The computer method is compared to the finite circular plane source equation and other methods.
