Kegunaan isotop platina
- 195mPt (with a half-life of 4 days) is used for pharmacokinetic studies of platinum-based anti-tumor agents in cancer diagnosis and cancer therapy. The m in the superscript of 195mPt indicates a metastable state of the isotope. 195mPt can be produced from the stable isotopes 192Os or 195Pt via the 192Os (α, n) 195mPt reaction and the 195Pt (n, n′) 195mPt reaction, respectively.
