Cadmium-109 is one of the nine most radioactive isotopes of cadmium. Cadmium-109 has 48 protons, 61 neutrons, and 48 electrons. Cadmium-109 has an amu of 108.90495. This isotope is a silver, transitional metal. It’s soft enough to be cut effortlessly with a knife. It is located under group 12 in period 5.

Cadmium-109 has multiple uses. It also has high radioactivity. Staurt Hunt & Associated Ltd. have observed, when ingested or inhaled at an unknown dosage the radioactivity causes damage to the lung tissues and kidneys. Cadmium-109 is typically used to evaluate metal alloys for checking stock and scrap sorting. This helps separate the different metals. It’s also known to be operated to construct measurement sources for 88 keV gamma radiation used for NASA.
