151 Eu is the beta decay product of samarium-151, but since this has a long decay half-life and short mean time to neutron absorption, most 151 Sm instead ends up as 152 Sm. 152 Eu (half-life 13.516 years) and 154 Eu (half-life 8.593 years) cannot be beta decay products because 152 Sm and 154 Sm are non-radioactive, but 154 Eu is the only long-lived "shielded" nuclide, other than 134 Cs, to have a fission yield of more than 2.5 parts per million fissions.

Standard Capsule For High Energy Gamma applications requiring a long half-life radionuclide, these sources offer a broad gamma spectrum between 122keV and I'm trying to find the branching ratio for Na-22. For that, I need to calibrate my detector sensitivity for different evergy levels. For that, I measured Eu-152 gamma spectrum, and now I wish to reference it to known values. I've been desperately Googling any query I can think of to find the required data, but I didn't find anything. hazard.

Eu 152 gamma spectrum

The ratio of Eu/ sup 154/ and Eu/sup 152/ was determined on the basis of the gamma quanta 1280(Eu/sup 154/) and 1411 (Fu/sup 152/)kev to be 0.21 plus or minus U.03. Energies and relative intensities for Eu/sup 152/ and Eu/sup 154/ are tabulated.

This is a table of commonly-observed gamma energies, arranged by increasing gamma energy. The parent isotope and its half life are listed with the gamma energy. The key gamma energy for an isotope has an asterisk following it. Each isotope is listed once with its complete set of gamma energies.
