MicroShield® | 辐射剂量计算软件

MicroShield^®是一款辐射剂量计算软件，它广泛应用于屏蔽体设计与屏蔽外参考点剂量率计算等方面。 该软件有16种源项模型并自带含12种屏蔽材料的材料库以及含大量放射性核素的核素库，用户还可以根据工程需要自行添加屏蔽材料，这些功能使用户在建模时有更广泛的选择范围。

MicroShield^®除了重视建模、核素参量输入等功能外，其结果是以Microsoft Office^®方式输出，方便用户对计算结果进行后续应用。

MicroShield^®是交互式的，并利用广泛的输入错误检查。集成工具提供结果图，材料和源文件创建，具有衰减的源推断（考虑衰变和子堆积的剂量——Ci计算），衰减的暴露率与实践的预测，材料和核素数据的访问和衰变热计算。

MicroShield^®现在有两个不同的版本：MicroShield^® Pro和MicroShield^® LT。MicroShield^® Pro提供MicroShield^®软件的全部功能以及各种源，衰变和其他剂量评估工具。MicroShield^® LT提供了基本的三维解决方案算法和基本功能。

 英文介绍

MicroShield^® is a comprehensive photon/gamma ray shielding and dose assessment program that is widely used for designing shields, estimating source strength from radiation measurements, minimizing exposure to people, and teaching shielding principles.

MicroShield^® is useful to health physicists, waste managers, design engineers, and radiological engineers and only requires a basic knowledge of radiation and shielding principles.

MicroShield^® is fully interactive and utilizes extensive input error checking. Integrated tools provide graphing of results, material and source file creation, source inference with decay (dose-to-Ci calculations accounting for decay and daughter buildup), projection of exposure rate versus time as a result of decay, access to material and nuclide data, and decay heat calculations.

MicroShield^® Version 12 Lastest Features:

MicroShield^® V12 includes multi-shield buildup factor calculations as well as

• Export results into the latest versions of Microsoft Word^® and Excel^®
  

• Faster computational run-times

• The installation process has been enhanced and is now compatible with Microsoft® System Center Configuration Manager

• The installation process can also be performed silently

• A Check for Update feature has been added to allow the user to check for the latest update

• Full Microsoft Windows^® 10 compatibility

  
  

MICROSHIELD’S^® FEATURES INCLUDE:

•  Full Microsoft Windows^® 8/8.1 (32 bit and 64 bit), Windows^® 7 (32 bit and 64 bit), Vista® and XP^®compatibility.

• Ability to export results into Microsoft Office^® applications.

• Ability to utilize international numerical formats (decimal commas, etc.).

• Current industry standard dose conversion factors including ICRP-116, ICRP-74, ICRP-51 as well as ANSI/ANS-6.1.1.

•  Sixteen geometries that accommodate offset dose points and as many as ten standard shields plus source self-shielding and cylinder cladding.

• The geometry display for entry is re-scaled as dimensions are entered. Dimensional data are accepted in meters, centimeters, feet, or inches.

• Library data (radionuclides, attenuation, buildup, and dose conversion) reflect standard data from industry standard radiation libraries ICRP-38 and ICRP-107 as well as ANSI/ANS standards and RSICC publications.

• Buildup and uncollided results are both automatically and simultaneously calculated.

• Sources may be created and saved and moved among cases (either as nuclides or energies) and as concentrations or totals.  Several photon grouping methods are provided including custom (user defined) grouping methods.

• Source decay can be calculated with daughter products generated using the same algorithms as found in the RadDecay^® software
