The calculation model is comparable to ORIGEN2 and provides equally reliable results. The calculation proceeds from the exposure start date to an exposure end date according to a stored power time history. Final activity estimates can be set to any date beginning from the end of exposure. Formatted results can be transferred directly from the output window to a spreadsheet or saved to a text file for later retrieval or editing outside of the program.

Change case settings on the fly and observe impact on results without having to edit an external file and restart the program. Include thermal neutron weighting in a single calculation without external data formatting, and transfer results directly from the result window to a spreadsheet or other document.

Conduct tradeoff studies between activity estimates and dose rates using the built-in point kernal shielding program Winshld.
