This study was conducted to investigate the factors affecting the removal of the long-lived radium isotopes, i.e., ²²⁶Ra (1600 y) and ²²⁸Ra (5.8 y), from PW associated with oil and natural gas production in certain Egyptian oilfield. The total radium concentration (²²⁶Ra + Ra²²⁸) in PW was found to be 164 Bq/L, i.e., 3.145 ng/L.

Traditional restoration methods, which rely on physical and chemical interventions as well as bioremediation, are economically burdensome and unsuitable for large-scale restoration efforts. Waste graphite of spent lithium-ion batteries (LIBs) is also a challenge to repurpose, yet its resourceful utilization is crucial in the context of the dual-carbon goals. In this study, layered graphene materials were successfully synthesized from spent LIBs anode materials by electrochemical exfoliation. Adsorption experiments revealed that the removal efficiency of Sr(II) and Cs(I) by the graphene increases with increasing pH from 1.0 to 6.0, achieving a higher adsorption at pH 6.0. The adsorption kinetics show that the adsorption of Sr(II) and Cs(I) on the graphene fits the pseudo-second-order kinetic model. Calculated from the Sips model, the maximum adsorption capacity for Sr(II) and Cs(I) is determined to be 73 mg/g and 55 mg/g, respectively, at pH 6.0 and 298 K. Furthermore, the graphene exhibited excellent regenerability, maintaining over 90 % of its adsorption capacity after four cycles. The adsorption mechanism involved a synergistic effect of monolayer uniform adsorption and non-uniform adsorption, where Sr(II) and Cs(I) occupied the active sites of the graphene material. These findings suggest that electrochemical exfoliation is a novel and effective approach for graphene synthesis, while waste graphite of spent LIBs hold a great potential for nuclear wastewater treatment and electrochemical exfoliation.</div></div>","PeriodicalId":15667,"journal":{"name":"Journal of environmental radioactivity","volume":"290 ","pages":"Article 107799"},"PeriodicalIF":2.1,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144933058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Animal welfare groups have provided care for these forsaken animals, oftentimes rescuing them and subsequently facilitating their adoption, or in some cases reuniting them with their original owners. However, these abandoned animals have adapted to a feral lifestyle, foraging for food and, in the process, accumulating low levels of internal radioactivity, effectively becoming sources of radiation themselves. Consequently, adoptive owners of rescued dogs and cats from Chernobyl and Fukushima may be exposed to low levels of radiation, which could potentially be a deterrent to some considering adoption. Monte Carlo N-Particle transport code was used to model various pet-owner bonding scenarios, enabling the estimation of total dose ranges. Evaluation of radiation doses to hypothetical owners in several exposure scenarios reveals that doses of significantly less than 1 mSv can be expected. Under a conservative scenario, a potential owner would receive an annual effective dose of 1.1 × 10⁻³ mSv from a contaminated dog or 3.6 × 10⁻⁶ mSv from a contaminated cat.
