Talk:Isotopes of technetium

43Tc Technetium stability data

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.WFPM (talk) 03:55, 18 April 2013 (UTC)

Could ⁹⁶Tc possibly undergo β- decay to ⁹⁶Ru?

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)

Decay of 99m

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)
