An attempt was made to grow α-LiIO₃ crystals from an aqueous solution of lithium iodate containing amino acids to enhance the nonlinear optical and mechanical properties of α-LiIO₃ crystals suitable for both academic and industrial applications. The grown bulk crystals were characterized by means of several complementary techniques, such as optical spectroscopy, IR spectroscopy, single-crystal X-ray diffraction, powder X-ray diffraction (PXRD), and measurements of the second harmonic generation efficiency. In the presence of an amino acid in the solution, an increase in the rate of crystal growth was experimentally observed. In the IR spectra of α-LiIO₃:L-Ala and α-LiIO₃:Gly crystals, absorption bands appear that are absent in pure lithium iodate, but are characteristic of amino acids. The lattice parameters of the grown crystals were confirmed through the X-ray technique. Single crystal X-ray and powder X-ray diffraction measurements revealed that pure, as well as α-LiIO₃:L-Ala and α-LiIO₃:Gly crystals maintained a hexagonal structure, remaining single-phase within the amino acid's concentration range (5 mol%), indicating that the presence of L-Ala and Gly in solution does not violate the parameters of the crystal lattice. It was obtained that the second harmonic generation activity of the α-LiIO₃:L-Ala and α-LiIO₃:Gly crystals is higher than that of the pure α-LiIO₃ crystal. The enhancement of the optical properties of α-LiIO₃:L-Ala and α-LiIO₃:Gly crystals in comparison with pure LiIO₃ has been precisely examined by UV–Visible spectral analysis within the wavelength range of 280–800 nm. UV–Visible spectral analysis is also used to evaluate the band gap.</div></div>","PeriodicalId":20861,"journal":{"name":"Radiation Physics and Chemistry","volume":"243 ","pages":"Article 113685"},"PeriodicalIF":2.8,"publicationDate":"2026-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146095725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The measured activity concentrations ranged from values below the minimum detectable limit (MDA = 2 Bq·kg⁻¹) up to 5.14 ± 0.11 Bq·kg⁻¹ for ²²⁶Ra, from below the MDA (2.5 Bq·kg⁻¹) up to 3.17 ± 0.04 Bq·kg⁻¹ for ²³²Th, and from 15.18 ± 0.08 Bq·kg⁻¹ to 47.14 ± 1.85 Bq·kg⁻¹ for ⁴⁰K.

This work presents a comprehensive Monte Carlo investigation of a novel Tri-Layer Adaptive Composite System (TACS) developed for radiation shielding in SNF transport and dry-storage casks. The proposed architecture adopts a functionally graded design composed of three optimized layers: a Refractory High-Entropy Alloy (RHEA) inner layer providing structural integrity and initial gamma attenuation, a Hydrogenated Boron Nitride (HBN) composite layer serving as the primary neutron moderator and absorber, and an outer Tungsten–Metallic Glass Matrix Composite (W-MGMC) layer delivering further suppression of residual gamma and neutron radiation. Radiation transport simulations were performed using MCNP5, modeling a homogenized pressurized water reactor (PWR) mixed-oxide (MOX) spent fuel assembly with a heavy-metal loading of 0.492 tHM and a representative burnup of 50 GWd tHM⁻¹. Conservative, bounding source terms were employed, assuming ¹³⁷Cs as the dominant gamma-emitting radionuclide and ²⁴⁴Cm as the primary neutron source via spontaneous fission, for cooling times up to 50 years. The results show smooth and monotonic attenuation of both photon and neutron fields across the multilayer system, with no localized dose-rate hot spots. Energy-dependent total microscopic photon cross-section analyses confirm substantial interaction probabilities in the high-Z RHEA and W-MGMC layers across the relevant energy range, explaining the rapid suppression of gamma flux and dose observed within these regions. At the same time, HBN exhibits minimal photon interaction consistent with its low-Z composition. Half-value layer (HVL) analysis further quantifies the shielding efficiency, revealing that RHEA and W-MGMC exhibit the smallest gamma HVLs (≈0.8 cm). In contrast, HBN provides the lowest neutron HVL (≈1.5 cm), confirming its dominant role in fast-neutron removal. At the cask surface, the TACS configuration achieves a total dose rate of approximately 0.10 mSv h⁻¹, corresponding to a safety margin of about 20 × below the IAEA SSR-6 transport limit. Comparative benchmarking against conventional Fe–PE–Pb and steel–air–concrete shielding configurations demonstrates the superior shielding efficiency and compactness of the proposed system, particularly for neutron-dominated, high-burnup MOX fuel inventories.</div></div>","PeriodicalId":20861,"journal":{"name":"Radiation Physics and Chemistry","volume":"243 ","pages":"Article 113663"},"PeriodicalIF":2.8,"publicationDate":"2026-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146047884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
