Selenium is a trace element in humans. It is used in free radical elimination and other antioxidant enzymes, and also plays a role in the functioning of the thyroid gland. Dietary selenium comes from cereals, meat, fish, and eggs. Brazil nuts are a particularly rich source of selenium. Selenium deficiency in healthy people is relatively rare.

Thallium bromide-iodide crystals have also been used in infrared detectors. The addition of metals like thallium to glass can also reduce its melting point to as low as 150 degrees centigrade. As such low-melting point glasses do not shatter like normal glasses, they are particularly useful for the manufacture of electronic parts.
