Technetium
6h1m
Medically used material
Used for imaging the heart muscle, lungs, brain, and the skeletal sys-
tem. Other uses include imaging the kidney, liver, thyroid, spleen, gall
bladder, salivary and lacrimal glands, and the heart blood pool. It is
also used to investigate other medical issues, like certain types of infec-
tions. Also used for tracing sewage and liquid waste movements within
city infrastructures. This nuclide is a ission product in nuclear reactors.
It can occur in the radioactive fall-out resulting from hazardous incid-
ents in nuclear power plants.
Thallium
3d1h
Medically used material
Used for diagnosing coronary artery disease and other heart problems.
Thorium
14.05 Ga
232
Th or
232
U
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. Used
in gas lantern mantles,
232
Th is also used in WIG welding rods. The
spectra of
232
Th and
232
U are very similar.
