Resumo
The assessment of internal occupational radiation exposures is generally
based on evaluating the retention of radioactive materials in the regions of
the body and their elimination through excreta. The mathematical
methodology to assess the internal dose from the incorporation of
radionuclide is based in compartmental models which simulate the transport
and the retention of the materials in the organs. The ICRP publications show
the compartmental models to the respiratory and gastrointestinal systems,
and the systemic distribution for distinct radionuclide which is of concern to
the radiation protection.
In this work, it is proposed a computational program to create and solve
compartmental models to be used in different applications. The main
objective of this software is to be used as a rapid development tool for
building news compartmental models, visualization and modification of the
transfer rate for sensitivity analysis studies.
The code was developed in the C# programming language, taking into
account the interface usability and easy models updates. The models are able
to be stored in different databases as Microsoft Access and SQL Server and
exported in XML format. The calculation engine module is based in semianalytical algorithm for solving first-order equation system.
The software was tested using the Human Respiratory and Human
Alimentary Tract Models with uranium biokinetic model presented in ICRP
Publication 78. The results obtained considering an acute intake by
inhalation were in accordance with predicted values presented by ICRP.
