Natural gallium Ga consists of a mixture of two stable isotope s gallium 69 and gallium 71. The most commercially important radioisotope s 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 which is used in standard nuclear medical imaging, in procedures usually referred to as gallium scan s. It is usually used as the free ion, Ga sup 3 sup . It is the longest lived radioisotope of gallium. The shorter lived gallium 68 half life 68 minutes is a positron emitting isotope which is generated from germanium 68 in gallium 68 generator s, for use in a small minority of diagnostic PET scan s. For this use, it is usually attached as a tracer to a carrier molecule, which gives the resulting radiopharmaceutical a different tissue uptake specificity from the ionic Ga 67 radioisotope normally used in standard gallium scans.

Aluminium gallium indium phosphide Aluminum Gallium Indium Phosphorus , also AlInGaP , InGaAlP , etc. is a semiconductor material . AlGaInP is used in manufacture of light emitting diode s of high brightness red, orange, green, and yellow color, to form the heterostructure emitting light. It is also used to make diode laser s. AlGaInP layer is often grown by heteroepitaxy on gallium arsenide or gallium phosphide in order to form a quantum well structure. Safety and toxicity aspects The toxicology of AlInGaP has not been fully investigated. The dust is an irritant to skin, eyes and lungs. The environment, health and safety aspects of aluminium indium gallium phosphide sources such as trimethylgallium , trimethylindium and phosphine and industrial hygiene monitoring studies of standard MOVPE sources have been reported recently in a review ref Environment, health and safety issues for sources used in MOVPE growth of compound semiconductors D V Shenai Khatkhate, R Goyette, R L DiCarlo and G Dripps, Journal of Crystal Growth, vol. 1 4, pp. 816 821 2004 doi 10.1016 j.jcrysgro.2004.09.007 ref .
