This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
The radioisotope thallium-201 (as the soluble chloride TlCl) is used in small amounts as an agent in a nuclear medicine scan, during one type of nuclear cardiac stress test. Soluble thallium salts (many of which are nearly tasteless) are highly toxic and they were historically used in rat poisons and insecticides. Because of their nonselective ...
By the mid-1970s, scientists and clinicians alike began using thallium-201 as the radioisotope of choice for human studies. [8] Individuals could be placed on a treadmill and be "stressed" by the "Bruce protocol" and when near peak performance, could be injected with thallium-201.

[1] [2] For thallium it may be used in addition to gastric lavage, activated charcoal, forced diuresis, and hemodialysis. [3] [4] It is given by mouth or nasogastric tube. [2] [4] Prussian blue is also used in the urine to test for G6PD deficiency. [5] Side effects may include constipation, low blood potassium, and stools that are dark.
The goal and objectives, the time frame, the stress test level and the total costs of the stress test are defined. Phase 2: Assessment, during which the stress test at the component and the system scope is performed, including fragility [12] and risk [13] analysis of the CIs for the stressors defined in Phase 1. The stress test can result in ...
