This work is concerned with the study of the radioactivity induced in various materials (Sc, Cu, Tb, Ta, W, Au) irradiated by hard Bremsstrahlung photons from an electron beam and by secondary neutrons induced by a proton beam. In both cases, the primary beam features an 18 MeV kinetic energy. We have performed Monte Carlo simulations with MCNP, GEANT4, FLUKA, and PHITS, coupled with the analytical codes CINDER'90 or FISPACT-II, to estimate the threshold reaction rates and the induced radioactivity in the samples. We compared the simulations with experimental activation measurements performed by high-resolution gamma spectrometry at a decommissioned medical LINAC and around the CYRCé cyclotron. We also used CR-39 solid-state nuclear track detectors to characterize the thermal and fast neutron components of the secondary fields.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":"200 16-18","pages":"1507-1513"},"PeriodicalIF":0.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142626322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The present study investigated the effect of X-irradiated normal human lung fibroblast WI-38 cells on the clonofenic potential of human lung cancer A549 cells by co-culturing them. Moreover, the relationship between the effects of co-culturing on the clonogenic potential of A549 cells and cellular senescence in WI-38 cells was investigated. The co-culture with 10-Gy-irradiated WI-38 cells and A549 cells enhanced the clonogenic potential of non- or X-irradiated A549 cells. Irradiated WI-38 cells exhibited high SA-β-gal activity, a cellular senescence hallmark. Importantly, treatment with senolytic drugs, which eliminate senescent cells, not only influenced high-SA-β-gal-activity cell percentages among the irradiated WI-38 cells but also the effect of irradiated WI-38 cells on the clonogenic potential of A549 cells. In conclusion, our results suggest that irradiated WI-38 cells promote A549 cell clonogenic potential and irradiated senescent WI-38 cells contribute to this effect.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":"200 16-18","pages":"1608-1614"},"PeriodicalIF":0.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142626783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The term 'disaster-related deaths' is commonly used in Japan; however, comprehensive studies in regions severely impacted by nuclear accidents are scarce. Our research primarily focuses on Minamisoma City, situated north of the Fukushima Daiichi Nuclear Power Plant (FDNPP), and aimed to study the risks associated with evacuation and disaster-related death. We introduce the following studies: (1) risks from evacuation in elderly care facilities after the FDNPP accident; (2) detailed case reports on hospital evacuation and (3) detailed reports on disaster-related deaths. A critical lesson from the FDNPP accident is the significant risk to life posed by evacuation actions taken to avoid radiation exposure. Despite evacuation being an effective measure to reduce exposure, our preparation and knowledge are insufficient for safe execution. This paper ensures that the lessons from Fukushima are leveraged in future radiation protection measures.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":"200 16-18","pages":"1524-1527"},"PeriodicalIF":0.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11561568/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142626914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Phase 1, FMU shared scientific facts on the relationship between radiation exposure and thyroid cancer, as well as the response of FMU towards those who read the letter and were concerned about the description. Furthermore, FMU organised lectures and workshops to facilitate peer support among medical and non-medical staff, which were publicised through a newspaper article. In Phase 2, the peer support programme targeting patients with thyroid cancer was launched. In Phase 3, FMU participated in a TV programme to explain the medical aspects of thyroid cancer and the importance of providing peer support to patients with cancer, featuring individuals with experiences as medical staff and survivors.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":"200 16-18","pages":"1519-1523"},"PeriodicalIF":0.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11561570/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142626530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, few studies have applied this method to pond water. This study tested the applicability of this reconstruction method in ponds within the Fukushima evacuation zone. Bottom sediments in ponds were collected in November 2019. Our reconstruction of a shallow closed pond disagreed with our observations. Even in ponds where the reconstruction agreed well with observations, underestimations may have occurred because the time constant for the decrease in 137Cs concentration was lower than those previously reported. We conclude that the present reconstruction method may be applied to deeper Fukushima ponds with inflow and outflow, but underestimations of initial 137Cs concentrations in water may lead to uncertainties. For realistic reconstruction, attention should be paid to pond characteristics, catchment conditions, and sediment core selection.","PeriodicalId":20795,"journal":{"name":"Radiation protection dosimetry","volume":"200 16-18","pages":"1840-1844"},"PeriodicalIF":0.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142626116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
