The radionuclide database lets you browse the built-in database for radionuclides and radionuclide decay chains. Radionuclide decay chains can be edited and then imported to the current project.
All elements and isotopes and decay information are included in the database.
The radionuclide database window lets you search both the database and your current model. You choose whether to search the database or model by selecting either Database or Model from the View drop-down list, at the bottom left of the window.
