Gallium - Wikipedia

Gallium is a chemical element with the symbol Ga and atomic number 31. Elemental gallium is a soft, silvery metal at standard temperature and pressure; however in its liquid state it becomes silvery white. If too much force is applied, the gallium may fracture conchoidally. It is in group 13 of the periodic table, and thus has similarities to the other metals of the group, aluminium, indium ...

Isotopes of gallium - Wikipedia

Natural gallium (31 Ga) consists of a mixture of two stable isotopes: gallium-69 and gallium-71.The most commercially important radioisotopes are gallium-67 and gallium-68.. Gallium-67 (half-life 3.3 days) is a gamma-emitting isotope (the gamma emitted immediately after electron-capture) used in standard nuclear medical imaging, in procedures usually referred to as gallium scans.

Gallium scans were negative for the pulmonary area in 23/36 scans (specificity 64%), and negative for paranasal activity in 13/16 scans (specificity 81%) in episodes without WG activity. Positive predictive value of WG activity for lungs and paranasal region was 24% and 63%, respectively, negative predictive value was 100% for both regions. False positive findings were caused by bacterial or ...

Gallium-68 generator - Wikipedia

The mobile phase is a solvent able to elute (wash out) gallium-68 (III) (68 Ga 3+) after it has been produced by electron capture decay from the immobilized (absorbed) germanium-68. Currently, such 68 Ga (III) is easily eluted with a few mL of 0.05 M, 0.1 M or 1.0 M hydrochloric acid from generators using metal-free tin dioxide or titanium dioxide adsorbents, respectively, within 1 to 2 ...
