Abstract Inhalation of 131 I is the main route for internal doses to nuclear medicine workers. This study aimed establish a simple analysis method determining activity in carbon cartridges, explore concentration departments, and evaluate dose A total 21 departments hospital conducted air sampling using high-volume sampler equipped with cartridges glass fiber filters collect gaseous aerosol I, respectively. Furthermore, mathematical model was developed analyze inhomogeneous distribution...
Abstract Radioactivity of 226Ra, 232Th, and 40K were measured in a total 92 samples, including eight commonly used types building materials that obtained from local manufacturers suppliers Beijing. Concentrations determined using high-purity germanium gamma-ray spectrometry. The activity concentrations all samples varied 10.1 to 661, 3.3 555 3.2 2945 Bq per kg with an average 127.8, 114.8, 701.5 kg, respectively. potential radiological hazards estimated by calculating the absorbed dose rate...
Cross sections for $(n,2n)$, $(n,p)$, $(n,{n}^{'}\ensuremath{\alpha})$, $(n,t)$, $(n,{d}^{'})$, and $(n,\ensuremath{\alpha})$ reactions have been measured on tantalum isotopes at the neutron energies of 13.5 to 14.7 MeV using activation technique. Data are reported following reactions: $^{181}\mathrm{Ta}(n,2n)^{180}\mathrm{Ta}{}^{g}$, $^{181}\mathrm{Ta}(n,p)^{181}\mathrm{Hf}$, $^{181}\mathrm{Ta}(n,{n}^{'}\ensuremath{\alpha})^{177}\mathrm{Lu}{}^{m}$,...
Cross sections for ($n,2n$), ($n,p$), ($n,\ensuremath{\alpha}$), and ($n,{d}^{*}$)${}^{1}$ reactions have been measured on ruthenium isotopes at the neutron energies of 13.5 to 14.8 MeV using activation technique in combination with high-resolution gamma-ray spectroscopy. Data are reported following reactions: $^{104}\mathrm{Ru}$($n,2n$)$^{103}\mathrm{Ru}$, $^{98}\mathrm{Ru}$($n,2n$)$^{97}\mathrm{Ru}$, $^{96}\mathrm{Ru}$($n,2n$)$^{95}\mathrm{Ru}$,...
After the nuclear accident at Fukushima Daiichi Nuclear Power Plant (Fukushima accident) in 2011, Japan quickly took emergency measures to reduce radiation hazards posed by released radioactive materials. As a neighboring country of across East China Sea, has also taken some corresponding prevention and control measures. continuously strengthened monitoring radioactivity food recent years. This paper discusses revision standards for food, improvement methods equipment, updating systems...
Abstract Intake of radionuclides and heavy metals through food consumption is one the important pathways for long-term health considerations. In this paper, dietary exposure to ( 210 Pb, Po, 226 Ra, 228 40 K, 137 Cs 129 I) (As, Hg, Cd U) adult residents in high background natural radiation area (HBNRA) Yangjiang, China, was comprehensively assessed using duplicate diet method. The estimated effective dose received by inhabitants HBNRA from ingestion 0.33 mSv/y, associated lifetime cancer...
Abstract In this study, the cross-sections of 129 Xe(n,n′) 129m Xe and 131 131m reactions were measured for first time within energy range 13.5–15.0 MeV based on 27 Al(n, α ) 24 Na monitor reaction cross-section. The experiment employed high-purity, high-pressure, highly enriched 129,131 isotope gas as target sample. This study marks instance in which cross-sections, corresponding correlation matrices, associated uncertainties are provided. TALYS-1.96 software was to obtain theoretical...
Abstract To investigate the levels of 131I activity in thyroid workers at place radioiodine therapy and their main influential factors China, 341 38 hospitals performing procedure five provinces were recruited to be measured 2021. A hand-held gamma spectrometer with NaI(Tl) probe was plastered thyroids thighs subjects during measurement, each measurement time 120 s. The internal exposure dose calculated, committed effective estimated. In 86 (25.22%) examined workers, above minimum detectable...
Transarterial chemoembolization (TACE) is currently the recommended treatment for intermediate-stage hepatocellular carcinoma (HCC). Liver resection (LR) may be an effective option, although recurrences are not uncommon. TACE prior to LR has been proposed as even better alternative.Patients with HCC who underwent curative were enrolled between January 2007 and December 2015. We compared overall survival (OS) recurrence-free (RFS) 2 groups using Kaplan-Meier method, we determined independent...
To explore the concentration level of radionuclide in mushrooms northeast China, and to analyze risk effective dose edible human body. A total 68 samples 18 species from three regions China Beijing as control were collected 2017 2020. The activity was measured by gamma-spectrometry, analyzed statistical analysis. relationship between 137Cs 40K content explored. 238U undetected all samples. 226Ra, 232Th, 40K, range 1–34.3, 2.26–32.3, 208–2,388 0.6–130.3 Bq/kg, respectively. concentrations not...
