The diffusion coefficient (α), the free-radon production rate (D), and gas permeability (K) of radon at different temperatures (20 °C, 0 °C, − 10 °C and − 20 °C) and water content saturation (m = 0 and m = 0.52) were determined by a self-made experiment device. The results showed that: (1) the free-radon production rate and the diffusion coefficient of uranium tailings increased with the increase of temperature in the range of 0.77–4.80 Bq·m−3·s−1 and 1.56 × 10–6–3.27 × 10–6 m2·s−1, respectively, when the temperature was in the range of − 20 to 20 °C. (2) With the increase of temperature, the free-radon production rate of dry uranium tailings and uranium tailings with a water saturation of 0.52 increased linearly, and the diffusion coefficient increased nonlinearly; (3) the permeability of uranium tailings with a water saturation of 0.52 at the same temperature was less than that of dry uranium tailing, and the former increased with increasing temperature, while the latter was the opposite. The methods and data obtained in this study can provide references for further research in this field, and the relevant results can be used to evaluate the potential environmental effects of radon migration parameters in uranium tailings ponds under different seasonal temperatures and water saturation conditions.</div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 1","pages":"439 - 447"},"PeriodicalIF":1.5,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143110131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As resistance to treatment has developed, particularly in the progressive stage of the disease and in the presence of microfocal multiple bone metastases, new generation radionuclide therapies have emerged.

In vivo, scintigraphy imaging visualized the accumulation of [161Tb]Tb-PSMA-617 in the prostate, kidneys, and bladder.

The dependence of cesium recovery degree on the sorption time was characterized using kinetic models of pseudo-first and pseudo-second order, the Elovich model, and also dependence of the sorbent capacity on the equilibrium concentration of cesium in solution using Langmuir and Freundlich isothermal models. It was found that sorption equilibrium is achieved in 8–20 h. Maximum capacity is achieved at the equilibrium concentration of cesium in the solution of more than 1500 mg L–1.

In this study, full energy peak efficiencies of gamma-rays for a high-purity germanium (HPGe) detector have been calculated. A geometry consisted of the HPGe detector and a volume source was constructed by using PHITS. The energy deposition to the HPGe was calculated for γ rays generated in the source. The full energy peak efficiency was estimated from counts of the full energy peak on the deposition distribution. The results obtained by PHITS simulations were validated by comparing with measured efficiencies (88–1836 keV) obtained from actual measurements of a nine-nuclide mix-standard source. The overall discrepancy between the simulated and measured data showed a maximum of 3.7% difference, which means with this method, the efficiency of gamma-ray detection by HPGe detector could be determined with a certain degree of certainty even in the absence of a standard sample.</div>","PeriodicalId":661,"journal":{"name":"Journal of Radioanalytical and Nuclear Chemistry","volume":"334 1","pages":"381 - 387"},"PeriodicalIF":1.5,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
