Abstract
All nuclear decay data within the 52 Fe-52m,52 Mn-52 Cr decay chain have been evaluated at IFIN-HH, Romania, as part of an IAEA coordinated research project (F41029) and incorporated into the Decay Data Evaluation Project (DDEP). Both 52 Fe and daughter 52 Mn are two potentially promising radionuclides to be incorporated into suitable radiopharmaceuticals for PET and SPECT imaging. The decay data evaluation of 52 Fe has previously been published and reported to the IAEA Nuclear Data Section. Equivalent DDEP evaluations for 52 Mn and 52m Mn have also been completed recently, and are presented in summary form below. These improved decay data sets have also been reported to the IAEA in detail, and are highly suitable in dose rate calculations for their application in nuclear medicine.
Highlights
Established in 1995, the Decay Data Evaluation Project (DDEP) is an international initiative with the main objective “to provide carefully produced recommended data for applied research and detector calibrations”, www.nucleide.org/DDEP.htm. This is achieved by performing peer-review evaluations for the following nuclear decay data of the radionuclides of interest: halflife, decay energy, decay modes and branching fractions, and radiation energies and emission probabilities
The results obtained for the main decay data of 52mMn and 52Mn are presented in Table 1: half-life, decay energy, and energies and emission probabilities of the different transitions
According to the SAISINUC testing tools, the sum of all the energies involved in the 52mMn decay (EC, γ, etc.), with the exception of the gamma-ray isomeric transition, is 5089.1 (36) keV, which is in very good agreement with the QEC value: 5088.9 (19) keV
Summary
Established in 1995, the Decay Data Evaluation Project (DDEP) is an international initiative with the main objective “to provide carefully produced recommended data for applied research and detector calibrations”, www.nucleide.org/DDEP.htm. This is achieved by performing peer-review evaluations for the following nuclear decay data of the radionuclides of interest: halflife, decay energy, decay modes and branching fractions, and radiation energies and emission probabilities. The aim of the present work was a complete characterization of the 52Fe-52m,52Mn-52Cr decay chain. The work was done under the IAEA Coordinated Research Project “Nuclear Data for Charged-particle Monitor Reactions and Medical Isotope Production”
