Kegunaan isotop rubidium
- 82Rb (with a half-life of 75 s) acts similarly to potassium and is used for imaging of the heart to better assess heart muscle function as a radioactive analog to potassium,. 82Rb is being considered as an alternative to highly-enriched uranium for producing medically important radioisotopes.
