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评估的一致性。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”为一个点源。这种方法是为NUREG / CR-0781(1979年5月)开发的,这是由NRC赞助的。
软件主要特点:
各种筒仓和墙壁几何形状。MicroSkyshine®接受名米,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任何一种
包括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
可创建多达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完美的。也就是说,不穿透墙壁的辐射是无法计算的
几何包括
墙壁后面的点源
墙壁后面的水平线源
墙后面的水平矩形区域源
墙后面的水平圆形区域源
墙后面的垂直线源
墙后的垂直矩形区域源
墙后的垂直圆形区域源
墙后面的矩形体积源
墙后的垂直圆柱体积源
墙后面的水平圆柱形源
矩形外壳中的点源

【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
Vertical Line Source Behind A Wall
Vertical Rectangular Area Source Behind A Wall
Vertical Circular Area Source Behind A Wall
Rectangular Volume Source Behind A Wall
Vertical Cylindrical Volume Source Behind A Wall
Horizontal Cylindrical Source Behind A Wall
Point Source In A Rectangular Enclosure
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.
