Twenty samples were collected in the uranium bearing region of Poli, Cameroon. α- and γ-spectrometry were used for radioactivity measurements. The range of activity concentrations for each radionuclide is 0.7 ± 0.3-3.5 ± 0.5 mBq.l−1 for 238U, 0.07 ± 0.03-2.1 ± 0.9 mBq.l−1 for 235U, 0.6 ± 0.2-5.1 ± 0.6 mBq.l−1 for 234U, 10 ± 1 mBq.l−1 for 226Ra, 10 ± 2-16.8 ± 2.2 mBq.l−1 for 210Po. Ingestion dose due to intake of 238U, 235U, 234U, 226Ra and 210Po in water was assessed for six age groups. The mean ingestion dose ranges from 8.8 μSv.yr−1 for adult to 123 μSv.yr−1 for infant, higher than the reference level of the committed effective dose (100 μSv.yr−1) recommended by the World Health Organisation (WHO). The uranium mass ranges between 0.014 μg.l−1 and 0.18 μg.l−1, below the reference mass which is 30 μg.l−1 showing that the uranium toxicity is low. 234U/238U isotopic ratio in water was observed with values near the equilibrium on 70% of collected samples and far from equilibrium reaching 3.09 in a borehole.","PeriodicalId":14141,"journal":{"name":"International Journal of Low Radiation","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48280906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Triangulated study design was used for data collection. In the quantitative part, 170 radiological technologists completed questionnaires with 95.5% response rate. The researcher used arbitrated checklist to evaluate medical imaging facilities. Census study was conducted on all radiological technologists and medical imaging departments at six main government hospitals in the Gaza Strip. In addition, three key informant interviews with radiological technologist managers were conducted. Researchers directly interviewed 170 participants. Findings revealed that there was shortage in number of radiographic equipment and radiological technologists. Generally, radiographic departments that followed standard in structure were 45%. Regarding fluoroscopic rooms, 79% of structure followed the standard. The majority of existing darkrooms fulfilled the international standard. An improvement in human resources among medical imaging facilities was clearly observed after 1996. An observable shortage is seen in number of radiographic machines and radiological technologists at all government hospitals. All departments revealed clear defects in structure, design and essential supplies.","PeriodicalId":14141,"journal":{"name":"International Journal of Low Radiation","volume":"11 1","pages":"78"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66669543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The potential correlation between local annual effective dose rates from natural sources and cancer mortality ratio (CMR), cancer incident ratio (CIR) and relative risk (RR) were analysed. All results are generally inconsistent and show both increase and decrease of CMRs, CIRs and RRs. However, the presented contradictions in trends of mortalities and incidents are statistically non-significant. Additionally, the data were adjusted to six confounding factors: people aged 70 or older, number of regular daily smokers etc. Based on these results, there is no regular trend observed for cancers related to natural background radiation in Poland, thus the popular linear no-threshold (LNT) hypothesis is not an accurate description of cancer risk prediction related to natural background radiation.","PeriodicalId":14141,"journal":{"name":"International Journal of Low Radiation","volume":"11 1","pages":"1"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66669439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
