Developer’s Description

By Computer Chemistry Consultancy

Calculate activity of a radionucid at a specified date.

From the developer: "The applet reads information (element, nuclide number, half life) from a database. Then the following calculations can be performed: activity at a certain date (whether in the future or in the past); date at which a certain activity will be (or was) reached. Dates can be entered either manually or by using the calendar buttons."
