A thallium stress test is a form of scintigraphy in which the amount of thallium in tissues correlates with tissue blood supply. Viable cardiac cells have normal Na + /K + ion-exchange pumps . The Tl + cation binds the K + pumps and is transported into the cells.
Thallium-201 is synthesized by the neutron activation of stable thallium in a nuclear reactor, [18] [19] or by the 203 Tl(p, 3n) 201 Pb nuclear reaction in cyclotrons, as 201 Pb naturally decays to 201 Tl afterwards. [20] It is a radiopharmaceutical, as it has good imaging characteristics without excessive patient radiation dose.
The thallium was slipped into bottles of Coca-Cola at the Carr and Trepal homes. [27] Thallium was the poison of choice for Saddam Hussein to use on dissidents, which even allowed for them to emigrate before dying. [28] In 1995, Zhu Ling was the victim of an unsolved attempted thallium poisoning in Beijing, China.

Example thallide monoclinic Cs 7.29 K 5.71 Tl 13 containing [Tl 6] 6− and [Tl 7] 7− clusters. Thallides are compounds containing anions composed of thallium.There are several thallium atoms in a cluster, and it does not occur as a single Tl − in thallides.
Thallium(I) sulfate is soluble in water and its toxic effects are derived from the thallium(I) cation. The mean lethal dose of thallium(I) sulfate for an adult is about 1 gram. Since thallium(I) sulfate is a simple powder with indistinctive properties, it can easily be mistaken for more innocuous chemicals.
Indium does not oxidize in air at ambient conditions. [109] Thallium is a soft, reactive metal (MH 1.0), so much so that it has no structural uses. [114] It has a close-packed crystalline structure (BCN 6+6) but an abnormally large interatomic distance that has been attributed to partial ionisation of the thallium atoms. [115]
Authorities in California have arrested a woman after they found more than two dozen dead horses on several properties this week. The woman is facing charges including criminal threats, cruelty to ...
