Th or

U
I
Naturally occurring radioactive material
Found naturally occurring in abundance within the earth crust, it is
not issile itself, but can be used to generate the issile element
233
U.
232
Th is used in gas lantern mantles and WIG welding rods. The spec-
tra of
232
Th and
232
U are very similar.

T
Special nuclear material
Used in nuclear power generators.
Although the United States
demonstrated/detonated in 1955 a
233
U based bomb core, the use of
233
U within a weapon is not as viable of a choice for a weapon when
compared to
235
U.

U-235
T
Special nuclear material
Can be effectively used to manufacture a nuclear ission weapon, and
is a primary concern because the design complexity required is far
less than that required for a
239
Pu based weapon.

Uranium
T
Special nuclear material
A mixture of
238
U and
235
U in various concentrations from depleted
to highly enriched
235
U. Can be effectively used to manufacture a nu-
clear ission weapon, and is a primary concern because the design
complexity required is far less than that required for a

Pu based
weapon.

Xe is used for blood low measurements and to image the heart,
lungs, and brain, for example, by means of tomography.
