Thallium stress test is a kind of nuclear scanning test that is conducted to test the activity of the heart in a state of rest as well as during physical exercise. Tweet. Not sure what college you want to attend yet? If you're like most people without a science background, you've probably never heard of this element. Thallium was also used in the treatment of malaria, ringworm of the scalp, tuberculosis, typhus, and venereal diseases. It has historically also been used as a rodenticide. Unfortunately, exposure to thallium metal is harmful to those working closely with the metal. This is the reason why 2 ppb that we ingest daily does not affect us. Thallium scanning can reveal areas of heart muscle that are deprived of a normal blood supply as a result of coronary artery occlusion. Thallium was also used to kill skin infections, but it is too toxic to be used for that now. Thallium has not been produced in the United States since 1984, but is imported for use in the manufacture of electronics, low temperature thermometers, optical lenses, and imitation precious jewels. Historically, thallium has been used in rat poison and insecticides. Presently our sources of thallium rely on naturally occurring deposits. Like most other metals in the periodic table, thallium has a high relative melting point and a high boiling point. Visit our online catalog directly for a complete listing of all thallium products.
