Radioactive Isotopes of Selenium, Bromine, and Rare Earth Elements

These isotopes can be obtained as fission products from reprocessing of the spent fuel elements. They are applied for medical purposes only in special cases because the products of reprocessing contain long-life fission products of the same ele­ments. The isotopes can be separated by mass spectrometry.

Sm-153: the production will be discussed in detail in Section 8.7.1.1.
