MicroSkyshine® calculates the photon dose from sky scattered gamma ray radiation.

MicroSkyshine® has been used to evaluate conformance with 10CFR50, Appendix I ALARA requirements as well as 40CFR190 fuel cycle exposure criteria.

Typical application would be to determine scattering from BWR turbine buildings, radwaste storage facilities, and waste disposal sites.

MicroSkyshine’s® analytical method of solution is based on the use of “beam functions” for a point source. This method was developed for NUREG/CR-0781 (May 1979), which resulted from an NRC sponsored effort. However, MicroSkyshine® reflects the efforts of analysts at Kansas State University, who further improved the method.
