Summary: This study presents new results on the decay of (180m)Ta, obtained through measurements on a tantalum sample stored underground for ten years. The study sets half-life limits on the decay process and tests hypothetical scenarios of dark matter-induced de-excitation of (180m)Ta, constraining the parameter space for strongly-interacting dark matter particles.

Summary: The relativistic coupled-cluster method was utilized to calculate various hyperfine-structure constants of low-lying states of Ra+, confirming the validity of the calculations. The study successfully extracted the electric quadrupole moments of Ra nuclei by combining theoretical and experimental data, and assessed the contribution of magnetic octupole hyperfine interaction to the hyperfine splitting. The sensitivity of hyperfine-structure interval measurements in Ra-223(+) was found to be on the order of kHz, revealing the effect of nuclear octupole moments.

Summary: This study analyzed the changes in 137Cs activity in game throughout Poland for the first time. It was found that in the most contaminated part known as the Opole Anomaly, the activity of 137Cs increases over time in the muscle tissues of game species. Despite passing its physical half-life period, 137Cs continues to migrate to game species due to unclear trophic dependencies.

Summary: In this study, the proton radioactivity half-lives of 33 spherical nuclei were systematically investigated based on the correlation between Skyrme parameters and macroscopic quantities of nuclear matter. A new Skyrme parameter set was obtained by fitting the two most weighted macroscopic quantities, and the theoretical proton radioactivity half-lives calculated using this new parameter set showed better agreement with experimental data compared to previous models.

Summary: Ho-166-based TARE procedures for liver cancer treatment can be safely conducted in hospitals. The study evaluated radioactive renal and intestinal excretions after TARE planning and treatment procedures with Ho-166-loaded microspheres and correlated them with the intratherapeutic effective half-life. The results showed that urine was the main excretion route, with low excretion proportions and weak correlations with the injected activities. The study demonstrated that this method can meet radioactive waste disposal regulations.

Summary: The study focuses on cluster decay half-lives of trans-lead nuclei emitting clusters like C, N, O, F, Ne, Mg and Si, incorporating various cluster pre-formation probabilities to the modified generalised liquid drop model (MGLDM). Calculated half-lives matched experimental values with standard deviations of 1.08, 0.995 and 1.07, leading to the formulation of a pre-formation factor equation with a standard deviation of 0.885. The applicability of four formulas in alpha decay from parent nuclei of atomic numbers 85-102 was demonstrated.

Summary: In nuclear fission, the spin of the fragments is actually generated after the nucleus splits, rather than before. There is no significant correlation between the spins of the fragment partners, and the average spin strongly depends on mass. The spin of the fragments does not exhibit notable dependence on the mass or charge of the partner nucleus, confirming the uncorrelated post-scission nature of the spin mechanism.

Summary: The study of the Pb-213 isotope reveals that its states can be characterized by the seniority quantum number. The conservation of seniority is a consequence of a geometric phase associated with particle-hole conjugation, observable in semi-magic nuclei. The gamma-ray spectroscopic observables in Pb-213 are influenced by both particle-hole conjugation and seniority conservation.

Summary: Direct lifetime measurements for excited states below previously reported isomers were performed using the FATIMA fast-timing LaBr3(Ce) array via gamma-gamma coincidences. The lifetimes below the I pi = 8+ seniority isomer in the N = 50 semi-magic 96Pd nucleus were studied as a benchmark for further analysis. The results confirm the published values for the I pi = 2+ and 4+ states, with improved accuracy achieved for the 4+ state lifetime.

Summary: This study reports on spectroscopic information and lifetime measurements of the neutron-rich I-135, I-137, and I-139 isotopes, providing the first lifetime data on iodine isotopes beyond neutron number 82. The excited states in fast neutron-induced fission were observed for the first time in these isotopes, with up to maximum spin-parity of (33/2(+)). The new spectroscopic information is compared to data from spontaneous or thermal-neutron induced fission and discusses the behavior of collectivity for the three valence-proton iodine chain with N = 82, 84, 86.

Summary: In this study, a cryogenic electrical-substitution radiometer was utilized for the primary calibration of monochromatic photon beams at a synchrotron facility, in order to determine the intrinsic efficiency and dead layer thickness of an HPGe detector. This calibration method allowed for the calculation of efficiency up to 55 keV, where the active thickness of the detector is not a determining factor. Geometrical efficiency was also determined through measurements of a radioactive source at various distances.

Summary: This study investigated the effect of patch source geometric parameters on the depth dose distribution in skin tissue through Monte Carlo simulation. The results showed that increasing the source-to-skin distance, patch thickness, and patch diameter will reduce the depth dose distribution, with the source-to-skin distance having the most significant impact on dose gradient.

Summary: In this study, the cross section values of the 109Ag(n,2n)108mAg reaction at different neutron energies were measured using the activation technique and off-line gamma-ray spectrometry. The results were compared with experimental data, evaluated data from libraries, and theoretical values to validate their accuracy.

Summary: The high-precision measurement of Rn-220 is crucial for assessing and preventing thoron radiological hazards. By adding a ZnS(Ag)-coated clapboard, the issue of reduced Rn-220 concentrations due to decreased air pressure can be addressed, leading to improved detection efficiency. Experimental and simulation results provide valuable references for establishing the Rn-220 calibration factor.

Summary: The leakage neutron spectra of Lead samples were measured using a TOF technique, and MCNP simulations with different nuclear data libraries showed that JENDL-5.0 and JEFF-3.3 libraries have better agreement with experimental data. Differences in spectra mainly stem from variations in neutron reaction channels across the libraries, with ENDF/B-VIII.0 and CENDL-3.2 libraries being overestimated in certain energy ranges.

Summary: This study investigates the radiation shielding properties and radiation protection applications of borotellurite glasses. The results show that the addition of TeO2 can enhance the glass's ability to absorb photons and fast neutrons, and effectively suppress photon buildup. These glasses also exhibit exceptional gamma radiation and fast neutron moderating abilities, making them suitable for designing lead-free, transparent, and efficient radiation protection structures.

Summary: This study investigated the accuracy and limitations of theoretical corrections in neutron-induced reactions on isotopically enriched Ge targets. Experimental cross-section measurements were conducted on several reactions using Ge-nat and isotopically enriched Ge targets. The results showed that the methodology using isotopically enriched targets provided accurate results without the need for theoretical corrections.

Summary: In gamma-ray spectrometric measurements, the decision threshold is determined by the observed value of the measurand. However, this dependence restricts its application to measurements with non-expressive indications. To address this issue, a recalculation of the decision thresholds based on the peak widths corresponding to expressive indications is proposed.
