Each material consists of a list of (nuclide, fraction) pairs where the nuclide is in the range 1 (hydrogen) through 94 (plutonium).
With larger spot size the width of this band is increased to not only one nuclide but up to four.
A nucleus is the kernel of a specific atom, and a nuclide is a certain element.
In addition to the cross section tables, each nuclide has two tables of data which relate to interpolations in scatter collisions when selecting a new energy and angle of deflection.
The concern is about whether the site is safe to contain the radioactinides and nuclides which might damage health and poison the environment.
The radioactivity will remain for much longer in the other nuclides.
This methodology is applicable to naturally occurring alpha-emitting nuclides and avoids large-scale studies of tumour induction.
Plutonium nuclides are so low as to be scarcely detectable.
