Biokmod: A Mathematica toolbox for solving system of differential equations, fitting coefficients, convolution, and more, with application for modeling Linear and Nonlinear Biokinetic Systems.   It included the current ICRP biokinetic models. It can be applied in pharmacokinetic, internal dosimetry,  bioassay evaluations,  nuclear medicine and more. This toolbox consist in Mathematica packages and tutorials . It can be downloaded here:BIOKMOD 5.4 (New, Mathematica 10 or later is requiered) or download the previous version here: BIOKMOD 5.3
