RadICalc: a program for estimating radiation intensity of radionuclide mixtures

RadICalc was developed to address the need for a computer program that could calculate the composition, activity, and measurable radiation of arbitrary radionuclide mixtures over time without significant effort from end-users. It provides an interface to perform decay calculations and can search and display the resulting data in graphical or tabular form. RadICalc can also determine radiation expected at specific masses with user-defined molecules in addition to atomic species for use in mass-based isotope separations for radiometric counting applications, a novel method under development at Pacific Northwest National Laboratory.
