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.

All of the remaining radioactive isotopes have half-lives that are less than an hour, and the majority of these have half-lives that are less than 3 minutes. This element has numerous meta states, with the most stable being 108m Ag (t * 418 years), 110m Ag (t * 249.79 days) and 106m Ag (t * 8.28 days).

Determine a so that A(t) = A_0a^t describes the amount of silver-108m left after t years, where A_0 is the amount at time t = 0. Die Half-Life-Saga erzählt die Geschichte von Gordon Freeman, einem Physiker, der in den Widerstand gegen außerirdische Invasoren gerät, die die Zukunft der Menschheit bedrohen. Seit dem Debüt von Half-Life im Jahr 1998 hat sich die Serie als Vorreiter für packende Action und eine fesselnde Geschichte etabliert.

Two excited states at 79.4+/-0.5 and 109.8+/-0.5 keV are established in Ag 108, with proposed spins and parities of 2- and 6+, respectively. The half-life of the 79-keV level has been shown to be <= 10 -9 sec. The spins and parities of the 1770- and 1048-keV levels in Pd 108 are assigned as 6+ (possibly 5+) and 4+, respectively.

The only radioactive isotope with a significant half life is Ag-108m (418 years) but it is only formed in trace quantities. After a short period in storage the produced Silver is almost entirely stable and safe to use.
