As per the 2006-2007 (87th edition) CRC handbook, the element 43 Technetium has 3 relatively long half-lived isotopes. They are: OE43TC97 with 4.2x10e^6 years (log half-life value = 14.1), OO43Tc98 with 6.6x10e^6 years (log half-life = 14.3, and Oe43Tc99 with 2.13x10e^5 years (log half-life = 12.8). On the heavier side of this grouping, the half-life is reported as falling off rapidly to the low values of only: 15.8 seconds (log half-life = 1.20 for OO43Tc100, and then only 5.3 seconds (log half-life = 0.72} for OO43TC102. However at OO43Tc104 has risen back to 18.2 minutes (log half-life = 3.04), which is a highly irregular variation in the noted half-lives of the OO Isotopes of this element.

This is energetically allowed, but perhaps will never happen (like the case of 150Eu). 129.104.241.214 ( talk) 11:32, 24 October 2023 (UTC)
According to the table 99mTc decays by IT or beta, but in the article nuclear isomer it decays by 140keV gamma, which seems more typicical for a nuclear isomer. 94.234.116.152 ( talk) 23:22, 12 December 2023 (UTC)
