Naturally occurring platinum is composed of five stable isotopes and one radioisotope, Pt-190, which has a very long half-life (over 6 billion years or 190 Ps). There are also many other radioisotopes with the most stable being Pt-193 with a half-life of 50 years.
This metal doesn’t normally cause health problems due to its unreactive nature but all compounds of platinum should be considered to be highly toxic. Platinum compounds rarely occur in nature.
