The palladium isotope 107Pd decays by beta emission to 107Ag having a 50 %-lifetime of 6.five million decades. Iron meteorites are the only real objects with a substantial-ample palladium-to-silver ratio to yield measurable variants in 107Ag abundance.
Metallic silver, like copper, is surely an antibacterial agent, which was regarded towards the ancients and initially scientifically investigated and named the oligodynamic effect by Carl Nägeli. Silver ions injury the metabolism of bacteria even at such small concentrations as 0.
