Radiation Data Analysis Tool (RaDAT)

Abstract

Radiation Data Analysis Tool (RaDAT), developed under a specific task order of ITER project, was designed using Matlab and it is a GUI (Graphical User Interface)-based compact application intended to support expert and non-expert users in: (1) visualization analysis of 2D radiation maps, (2) radiation qualifications of electronic equipment and (3) Occupational Radiation Exposure (ORE) analysis.It was certified for Protection Important Activities (PIA) and authorized to be used for equipment radiation qualification activities. Its main functionalities allow: (1) to visualize quickly 2D radiation maps (.VTR/.VTK files) on different planes and positions, investigating radiation conditions in different spots of the Tokamak Complex Building (TCB); (2) to analyse automatically radiation conditions of lists of millions of equipment volumes (.STL files), providing the best and the worst radiation conditions on Excel tables; (3) to calculate the total biological dose cumulated by a worker along a specific route, passing from a workstation to another, in the TCB. Another feature implemented in RaDAT is the Flexibility Radius (FR) option, which could be applied to the volumes, extending them by this FR, in order to take into account any possible relocation in proximity of the nominal installation spot.RaDAT allows reducing the analysis time considerably. It is capable to analyse one radiation map, finding the best and the worst radiation conditions within a single volume (e.g.: an electrical enclosure) in ∼ 50 ms, using a standard office laptop, reducing the analysis time by a factor ∼1000, compared to a manual analysis approach on standard visualization tools.
