: 2 The silvery-white color of barium metal rapidly vanishes upon oxidation in air yielding a dark gray layer containing the oxide.Barium has a medium specific weight and high electrical conductivity. Jan 23 2021 10:20 AM Especially barium has 4 stable isotopes like Ba-132, Ba-134, Ba-136 and Ba-138 with S =0 and 2 stable isotopes like Ba-135 and Ba-137 with S =+3/2.

7,7 (1). The activity of the Ba-137m is measured as a function of time by detecting the gamma rays that are emitted and the half-life is computed from the decay rate At high dose rate, electron beams are capable of delivering 25 kGy in minutes compared to in hours by gamma rays. •.

Naturally occurring barium (56 Ba) is a mix of six stable isotopes and one very long-lived radioactive primordial isotope, barium-130, identified as being unstable by geochemical means (from analysis of the presence of its daughter xenon-130 in rocks) in 2001.
