Visiplan

Introduction

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.
