【英文介绍】

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

?

MicroSkyshine^? has been used to evaluate conformance with:

?

? 10CFR50, Appendix I ALARA requirements

?

? 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.

MicroSkyshine’s^? Technical Features:

• A variety of silo and wall geometries. MicroSkyshine^? accepts dimensional data in meters, centimeters, feet, or inches.

• The scattering medium is air, and the Berger method is used for calculating buildup in an overhead shield. Any one of seven materials can be selected for this purpose.

• Library data for radionuclides, attenuation, and buildup are included.

• Source decay can be calculated and daughters generated.

• As many as twenty energy groups (with an energy range of 100 keV-10 MeV) may be created; total concentration entries are automatically converted to curies.

• All calculations performed by MicroSkyshine^? assume that the silo wall or vertical wall is a perfect shield; that is, radiation through the walls will not be calculated.

MicroSkyshine? Enhanced Software Features:

• Microsoft Windows interface.

• Fully interactive input processing and input error checking.

• The main menu allows you to create, save, load, erase, and run many cases. You can change one data entry without having to pass through the entire input sequence.

• Batch Processing – Multiple cases can be run in Batch mode

• Sensivity Runs – Several parameters can be examines to determine the resulting dose rate.

• Results can be saved in text, HTML, Microsoft Word, and Excel formats.
