    VISIPLAN是比利时核能研究中心开发的ALARA分析软件。作为世界上应用最广泛的辐射防护最优化计算软件,VISIPLAN提供了方便、快捷的3D建模方式,快速的源项计算方法以及路径规划方法。

    VISIPLAN 剂量评估程序,以协助的ALARA分析师岗前研究。VISIPLAN工具协助完成ALARA评估中的计算和通信。


软件特点:

- 代码是基于3D模型,包括材料,几何形状和物质来源

- 使用点内核剂量计算方法,并建立校正方法

- 代码允许执行任务,如轨迹和场景的剂量评估

- 特殊工具可用于测量剂量率集源敏感性分析和源强度的测定


【英文介绍】

VISIPLAN is a dose assessment program developed to assist the ALARA analyst in pre-job studies. The VISIPLAN tools assist both in the calculation and the communication in ALARA evaluations.


Specifications

> The code is based on a 3D model including material, geometry and sources.

> The Point-kernel dose calculation method, with build-up correction is used.

> The code allows to perform dose assessment for tasks, trajectories and scenarios. It estimates individual and collective dose.

> Special tools are available for source sensitivity analysis and source strength determination from measured dose rate sets.
