Technetium
Technetium-99m is the most widely used radioisotope in nuclear medicine: with a half-life of about 6 hours and 140 keV gamma emission, it is the tracer in about 85% of diagnostic scans, such as bone, heart and thyroid scans. This family brings together other impurities.
Did you know?Technetium was discovered in 1937 at the University of Palermo by Carlo Perrier and Emilio Segrè; university officials proposed 'panormium', from Panormus, Latin for Palermo, but the Greek technetos, 'artificial', prevailed.
