Gold-198 (198 Au) is a radioactive isotope of gold. It undergoes beta decay to stable 198 Hg with a half-life of 2.69464 days. The decay properties of 198 Au have led to widespread interest in its potential use in radiotherapy for cancer treatments. This isotope has also found use in nuclear weapons research and as a radioactive tracer in ...
Gold is currently considered the heaviest monoisotopic element. Bismuth formerly held that distinction until alpha-decay of the 209 Bi isotope was observed. All isotopes of gold are either radioactive or, in the case of 197 Au, observationally stable , meaning that 197 Au is predicted to be radioactive but no actual decay has been observed.

The following table lists the largest biotechnology and pharmaceutical companies ranked by revenue in billion USD. The change column indicates the company's relative position in this list compared to its relative position in the preceding year; i.e., an increase would be moving closer to rank 1 and vice versa.

Radioactive isotopes that have been suggested for salted bombs include gold-198, tantalum-182, zinc-65, and cobalt-60. [1] Sodium-23, the only stable isotope, has also been proposed as a casing for a salted bomb. Neutron flux would activate it to 24 Na, which would produce intense gamma-ray emissions for several days after the detonation.
