“…These two values agree within the stated uncertainties (the relative difference is about 0.22%); however, this difference of about 10 keV might be explained by two gamma-rays of high energy and very low emission intensity that are not yet placed in the decay scheme [4]: 1441(1) keV and 1839.14(17) keV.…”

Abstract. All nuclear decay data within the 52 Fe52m,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.

“…The most recent ENSDF evaluation for the mass chain A=52 was studied [4]. The energy of the nuclear levels, and the spin and parity values were adopted from this evaluation, while the total decay energies are from the atomic mass evaluation [5].…”

“…The energy calibration at high energy was performed using the γ lines observed in the decay of 52 Co, 6 + (Section IV). This procedure gave an energy of 5185(10) keV for the above γ-ray, which was then attributed to the 2 + → 2 + transition between the 2 + IAS in 52 Fe (at 6034(5) and/or 6044(5) keV [10,18], where having one or both states does not change our conclusions) and the 849 keV level [ Fig. 3(a)].…”

“…4(b) and (c), respectively]. The γ-ray seen at 1910 keV corresponds to a 2 + → 2 + transition between the 2759 and 849 keV known levels [10] in 52 Fe [ Fig. 3(a)] and it is expected to be seen in the decay of the 52 Co, 2 + isomer [8].…”

“…[12], as well as the data analysis procedures employed. (10) [12], we have assumed for the last level an energy of 378(50) keV from the value in the mirror nucleus 52 Mn, 377.749(5) keV [10,16], fixing in this way the excitation energies for the 52 Co levels. The error of 50 keV on the 378 keV level energy, which accounts for possible mirror energy differences (MED), was estimated in Ref.…”

Observation of the 2+ isomer in Co52

We report the first observation of the 2 + isomer in 52 Co, produced in the β decay of the 0 + , 52 Ni ground state. We have observed three γ-rays at 849, 1910, and 5185 keV characterizing the β deexcitation of the isomer. We have measured a half-life of 102(6) ms for the isomeric state. The Fermi and Gamow-Teller transition strengths for the β decay of 52m Co to 52 Fe have been determined. We also add new information on the β decay of the 6 + , 52 Co ground state, for which we have measured a half-life of 112(3) ms.

High energy radiotherapy can produce contaminant neutrons through the photonuclear effect. Patients receiving external beam radiation therapy to the pelvis may have high‐density hip prostheses. Metallic materials such as those in hip prostheses, often have high cross‐sections for neutron interaction. In this study, Thackray (UK) prosthetic hips have been irradiated by 18 MV radiotherapy beams to evaluate the additional dose to patients from the activation products. Hips were irradiated in‐ and out‐of field at various distances from the beam isocenter to assess activation caused in‐field by photo‐activation, and neutron activation which occurs both in and out‐of‐field. NaI(Tl) scintillator detectors were used to measure the subsequent gamma‐ray emissions and their half‐lives. High sensitivity Mg, Cu, P doped LiF thermoluminescence dosimeter chips (TLD‐100H) were used to measure the subsequent dose at the surface of a prosthesis over the 12 h following an in‐field irradiation of 10,000 MU to a hip prosthesis located at the beam isocenter in a water phantom. 53Fe, 56Mn, and 52V were identified within the hip following irradiation by radiotherapy beams. The dose measured at the surface of a prosthesis following irradiation in a water phantom was 0.20 mGy over 12 h. The dose at the surface of prostheses irradiated to 200 MU was below the limit of detection (0.05 mGy) of the TLD100H. Prosthetic hips are activated by incident photons and neutrons in high energy radiotherapy, however, the dose resulting from activation is very small.
