Estimation of internal exposure for exposed personnel from a Candu nuclear fuel factory

The knowledge of the radioactive material behavior inside the human body is an essential issue for interpretation of the radioactivity measurements in human body or excretions in terms of internal contamination or committed equivalent dose. The paper present evaluation of internal contamination of professionally exposed workers from a Candu nuclear fuel factory with the ACRO computer code which estimate burden and tissue or organ dose resulting from inhalation or ingestion of radioactive materials. The workplaces where continuos aerosols sampling are carried out, has been taken into account for the analysis. For potentially inhaled activity assessment, the average aerosol concentrations were estimated. The dose equivalent and collective dose equivalent are also estimated. (authors)
