Individual dose assessment of workers

Two examples of individual dose assessment of workers in special monitoring programs are presented, a uranium and an americium incorporation case. It is demonstrated that careful model modifications lead to better dose estimates but that in many cases an optimisation of parameters is not necessary to get a reliable assessment of the committed effective dose. In some cases the use of individual SEE values might be more sensitive with regard to the committed effective dose than very sophisticated modifications of biokinetic models. (author)
