“Material” is the term used in Ecolego to identify the modelled items, for example contaminants like radionuclides or chemicals. In other software and literature, material is sometimes referred to as “species”.
Requires Radionuclide Toolbox. A radionuclide is a special type of material which also has radioactive properties such as half life, element, atomic number etc. When you add radionuclides to your model, Ecolego will automatically handle nuclide decay and in-growth.

With the Radionuclide Toolbox you will be presented with another button used to a add radionuclides. Clicking the button will display a window
The Filters section allows you to search the database:
One of the advantages with this window is that it allows you to add several radionuclides at the same time.
The material editor is shown by right-clicking the material in a window and selecting Edit. In the Materials window, you can also show the editor by selecting the material and clicking the button, or by double-clicking the right-most “validation” column of the material in the table.
The material editor has two tabs:
This page lets you edit basic properties such as name and unit. See editing properties for more information.
This page is only available when editing radionuclides.
Mass number - The mass number of the radionuclide
Atomic number - The atomic number of the radionuclide
Halflife - The atomic halflife of the radionuclide. The Time unit drop down list can be used to select a unit for the halflife.
Decay constant - Lets you, as an alternative to enter the atomic halflife, enter the radionuclide decay constant.
