WebThallium poisoning is poisoning that is due to thallium and its compounds, which are often highly toxic. Contact with skin is dangerous and adequate ventilation should be provided when melting this metal. Many thallium compounds are highly soluble in water and are readily absorbed through the skin.

WebThallium Perfusion testing is used to evaluate the viability of the heart muscle. It is a scan (gamma camera or photoscan) involving the use of thallium-201, a radioisotope. Thallium accumulates evenly in normal heart muscle, but poorly or not at all in injured heart muscle. cytometry labWebThallium poisoning is via ingestion or absorption through the skin. The lethal dose for humans is 15-20 mg/kg, although much small doses have also led to death. Non-lethal doses cause toxic effects. Prolonged exposure may lead to build-up and chronic poisoning. bing christmas picturesWebThallium-201 is a cyclotron-produced radionuclide that decays by electron capture, with a half-life of about 73 hours. On decay, the major emissions are characteristic x-rays of the daughter product, mercury-201 ( 201 Hg), with an energy range of 69 to 81 keV.
