Computer simulation of radiation fields when designing and using gamma-irradiation facilities

A CRSF computer program for a 16-bit personal computer for calculation of the radiation field characteristics is offered. In combination with the standard mathematical programme, based on the Method of Feasible Directions-algorithm, the maximum possible volumes are calculated in which given material is to be placed for irradiation having preset uniformity - data, which enrich the information of the traditional two-dimensional distributions. A geometrical approach is used where the object is described by means of equations and inequalities setting its surface. (author)
