Kegunaan isotop emas
- 195Au (with a half-life of about 0.51 year) has been used to study particle movement within the lungs of rats. 198Au (with a half-life of 2.7 days) was used in a study to model gold cycling in plants. This study demonstrated that gold particles are retained by humates (organic constituents of soil), which contain fulvic acid, humic acid, ulmic acid, and lignin and would therefore be likely to accumulate in mull humus or forest litter.
