Where is gallium commonly found?
It is present in trace amounts in the minerals diaspore, sphalerite, germanite, bauxite and coal. It is mainly produced as a by-product of zinc refining. The metal can be obtained by electrolysis of a solution of gallium(III) hydroxide in potassium hydroxide.
Can you eat gallium?
Although it is not harmful in small amounts, gallium should not be purposefully consumed in large doses. For example, acute exposure to gallium(III) chloride can cause throat irritation, difficulty breathing, chest pain, and its fumes can cause even very serious conditions such as pulmonary edema and partial paralysis.

What makes gallium unique?
A unique metal Gallium is a post-transition metal. Even with such a low melting point, gallium’s boiling point is quite high at 3,999 F (2,204 C), giving it one of the greatest ratios between melting point and boiling point of any element.
How is gallium useful?
Most gallium is used in electronics. It’s common in semiconductors, transistors, and very small electronic devices. Gallium is able to turn electricity into light, so it’s also used to make LEDs. It can also be used to make thermometers and mirrors.
Does gallium react with water?
Gallium does not react with water at temperatures up to 100 °C (212 °F) but reacts slowly with hydrochloric and other mineral acids to give the gallium ion, Ga3+.
How do you remove gallium from skin?
* On skin contact with Gallium, immediately wash or shower to remove the chemical. * On skin contact with Gallium, immediately wash or shower to remove the chemical. At the end of the workshift, wash any areas of the body that may have contacted Gallium, whether or not known skin contact has occurred.
What are the uses of gallium 67?
Gallium-67 is an injectable radiopharmaceutical that is used with single photon emission computed tomography (SPECT) or SPECT/computed tomography (CT) imaging to detect the presence of acute inflammatory lesions and various malignancies including Hodgkin’s disease, lymphomas, and bronchogenic carcinomas.
What type of radiation is gallium-67?
Gallium-67 has a physical half-life of 78.3 hours and decays by electron capture, emitting gamma radiation.
How is a gallium scan done?
A gallium scan uses gallium citrate. It’s a drug that has very small amounts of radioactive gallium. A day or two before your scan, your healthcare provider injects the gallium citrate into a vein in your arm. The gallium then travels all over your body.
When was gallium-67 first used?
The use of gallium radionuclides in nuclear medicine dates back to the late 1940s, following the observation in toxicologic studies that gallium tended to localize to a high degree at sites of osteogenic activity.
What is the mass number of gallium 67?
66.92820
Who discovered GA 67?
Gallium was one of the first radioisotopes used for diagnostic nuclear medicine. Gallium, discovered in 1875 by Paul-Émile Lecoq de Boisbaudran, was first considered for diagnostic and therapeutic medical use in the 1940s by the research of H. C. Dudley and his co-workers.
