MicroSkyshine ® | 伽马射线辐射剂量计算软件

MicroSkyshine ^®软件用于计算天空散射的γ 射线光子剂量。

MicroSkyshine ^®已用于10CFR50评估。典型的应用是确定BWR涡轮机建筑物，放射性废物储存和废物处理场所的散射。MicroSkyshine^®的溶液分析法是基于使用“梁函数”为点源。这种方法是为NUREG / CR-0781（1979年5月）开发的，这是由NRC赞助的。

软件主要：

• 筒仓和墙壁几何形状。MicroSkyshine^®接受以米，厘米，英尺或英寸三维数据
  

• 散射介质是空气，Berger方法用于计算顶部屏蔽中的累积。可以为此目的选择其中材料中的一种

• 放射性核素的库数据，衰减和累积

• 可以计算源衰减并生成子元素

• 可创建20个能源库（具备100 keV-10 MeV的能量范围）；总浓度条自动转换为curies

• 通过MicroSkyshine执行中的计算，假设仓壁或垂直壁是的。也就是说，不穿透墙壁的辐射是无法计算的

【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.
  

Geometries Included:

• Point Source In A Silo

• Vertical Line Source In A Silo
  

• Vertical Cylinder Source In A Silo
  

• Point Source Behind A Wall
  

• Horizontal Line Source Behind A Wall
  

• Horizontal Rectangular Area Source Behind A Wall
  

• Horizontal Circular Area Source Behind A Wall

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.
