Water around the Geita Gold Mine in Tanzania was assessed by high-purity germanium gamma spectrometry to quantify the activity concentrations of 226Ra, 232Th, and 40K, and computed age-stratified ingestion doses and risk indices were determined. The average activity concentrations were 57 mBq L−1 for 226Ra and 5026 mBq L−1 for 40K, while the activity concentrations of 232Th were below the detection limit in all samples. The estimated adult fatal cancer risk ranged from 0.9 × 10−6 to 3.1 × 10−6 (mean 2.0 × 10−6). The excess lifetime hereditary effect ranged from 2.0 × 10−6 to 7.3 × 10−6 for males (average 4.5 × 10−6 ± 1.5 × 10−6) and 2.1 × 10−6 to 7.7 × 10−6 for females (average 4.8 × 10−6 ± 1.6 × 10−6). One-way ANOVA and Pearson correlations indicated significant spatial variation in activities and indices across sites and age groups. Under current conditions, waters appear to be radiologically safe. However, mine-adjacent hotspots warrant targeted surveillance. The obtained results provide a baseline for sound monitoring approaches at the Geita Gold Mine and other mines showing similar activity profiles."}]}],"bf:provisionActivity":[{"@type":"bf:Publication","bf:agent":[{"@type":"schema:Organization","schema:name":[{"@value":"MDPI"}]}]}],"dce:subject":[{"@type":"skos:Concept","skos:prefLabel":[{"@language":"eng","@value":"ingestion dose"}]},{"@type":"skos:Concept","skos:prefLabel":[{"@language":"eng","@value":"natural radioactivity"}]},{"@type":"skos:Concept","skos:prefLabel":[{"@language":"eng","@value":"radiological risk assessment"}]},{"@type":"skos:Concept","skos:prefLabel":[{"@language":"eng","@value":"radioactive material"}]},{"@type":"skos:Concept","skos:prefLabel":[{"@language":"eng","@value":"water quality monitoring"}]},{"@type":"skos:Concept","skos:prefLabel":[{"@language":"eng","@value":"Geita Gold Mine"}]}],"dce:title":[{"@type":"bf:Title","bf:mainTitle":[{"@language":"eng","@value":"Age-Stratified Spatial Radiological Risk Assessment of 226Ra 232Th and 40K in Water Surrounding the Geita Gold Mine in Tanzania"}]}],"dcterms:issued":["2025-09-16"],"dcterms:language":["eng"],"dcterms:type":[{"@type":"skos:Concept","skos:exactMatch":["https:\/\/pid.phaidra.org\/vocabulary\/69ZZ-2KGX"],"skos:prefLabel":[{"@language":"eng","@value":"Text"},{"@language":"deu","@value":"Text"},{"@language":"ita","@value":"Testo"}]}],"ebucore:filename":["jox-15-00152.pdf"],"ebucore:hasMimeType":["application\/pdf"],"edm:hasType":[{"@type":"skos:Concept","skos:exactMatch":["https:\/\/pid.phaidra.org\/vocabulary\/VKA6-9XTY"],"skos:prefLabel":[{"@language":"eng","@value":"journal article"},{"@language":"deu","@value":"Wissenschaftlicher Artikel"},{"@language":"ita","@value":"Articolo di rivista"}]}],"edm:rights":["http:\/\/creativecommons.org\/licenses\/by\/4.0\/"],"rdam:P30004":[{"@type":"ids:doi","@value":"10.3390\/jox15050152"}],"rdau:P60193":[{"@type":"schema:CreativeWork","bibo:issue":["5"],"bibo:volume":["15"],"dce:title":[{"@type":"bf:Title","bf:mainTitle":[{"@language":"eng","@value":"Journal of Xenobiotics"}]}]}],"role:aut":[{"@type":"schema:Person","schema:affiliation":[{"@type":"schema:Organization","schema:name":[{"@value":"Nelson Mandela African Institution of Science and Technology"}],"skos:exactMatch":["https:\/\/ror.org\/041vsn055"]}],"schema:familyName":[{"@value":"Mwimanzi"}],"schema:givenName":[{"@value":"Jerome M."}],"skos:exactMatch":[{"@type":"ids:orcid","@value":"0000-0002-9068-528X"}]},{"@type":"schema:Person","schema:affiliation":[{"@type":"schema:Organization","schema:name":[{"@value":"Universität für Weiterbildung Krems"}],"skos:exactMatch":["https:\/\/ror.org\/03ef4a036"]}],"schema:familyName":[{"@value":"Haneklaus"}],"schema:givenName":[{"@value":"Nils H."}],"skos:exactMatch":[{"@type":"ids:orcid","@value":"0000-0002-0673-0376"}]},{"@type":"schema:Person","schema:affiliation":[{"@type":"schema:Organization","schema:name":[{"@value":"University of Dar es Salaam"}],"skos:exactMatch":["https:\/\/ror.org\/0479aed98"]}],"schema:familyName":[{"@value":"Lolila"}],"schema:givenName":[{"@value":"Farida"}]},{"@type":"schema:Organization","schema:name":[{"@value":"et al"}]}]}
