1. The Radiation Laboratory's part was to develop an electromagnetic isotope separation process. 2. Publication of research into uranium, fission and isotope separation was now banned. 3. Hertz conducted research activities in isotope separation , which effected M�hlenpfordt s career interests. 4. Laser isotope separation , however, if developed to operational status, could be quite compact. 5. Electromagnetic isotope separation has been largely abandoned in favour of more effective methods. 6. Cascades are most commonly used in isotope separation , distillation, purification processes. 7. Enrichment is accomplished using one or more methods of isotope separation . 8. During World War II, Lawrence developed electromagnetic isotope separation at the Radiation Laboratory. 9. Chalabi said he was involved in the isotope separation program for nuclear weapons. 10. At Exxon he created many patents utilizing laser isotope separation .
