$a The first artificially produced element and a radioactive fission product of URANIUM. Technetium has the atomic symbol Tc, and atomic number 43. All technetium isotopes are radioactive. Technetium 99m (m=metastable) which is the decay product of Molybdenum 99, has a half-life of about 6 hours and is used diagnostically as a radioactive imaging agent. Technetium 99 which is a decay product of technetium 99m, has a half-life of 210,000 years. $8 eng 450 $a Technetium 99m $5 e $8 eng 550 $3 sllk_un_auth*d015609 $Y Organotechnetium Compounds $5 F $a zlúčeniny organotechnéciové 686 $a D01.268.271.870 686 $a D01.268.556.843 686 $a D01.268.956.875 686 $a D01.496.749.305.870 686 $a D01.552.544.843 750 $a Technetium $8 eng 801 -0
