________________________________________________________________. PHYSICAL CHARACTERISTICS: HALF-LIFE: 249.9 days TYPE DECAY: isomeric transition, beta -. beta- energies (MeV): 0.53 (30%), 0.083 (67.5%) The half-lives were found to be (3.91±0.09)y and (249±3)d, respectively. Possible effects of the recently detected Ag 108m isotope on the determination of the half-live of Ag 110m have been considered. Additional measurements gave a value for the Ag 110m activation resonance integral of (38±8)b.

The ground state has a 2.37 min half-life and a large $\beta ^{-}$ decay branch with Q$_{\beta -}$ = 1.649 MeV. While these traits make the isomer a good candidate for energy storage, the rarity of its natural decays makes it difficult to utilize its stored energy.
It also emits several intense gamma-rays of suitable energy. It has a longer half-life, 438 years, compared to 110mAg. Therefore, it is more suitable for this type of calibration standard.
