A comprehensive radiological survey using multivariate statistical analysis was carried out to evaluate the distribution of 40K, 232Th, 226Ra, 235U, and 137Cs, associated radiation indices in beach sand samples coastal area Aegean Sea. The activity concentration selected radionuclides measured no clue recent migration radiocaesium by not only precipitation but also through an indirect way, such as ocean runoff, found. As part risk assessment, external hazard index, radium equivalent...
A comprehensive study was carried out to measure indoor radon/thoron concentrations in 78 dwellings and soil-gas radon the city of Mashhad, Iran during two seasons, using common monitoring devices (NRPB RADUET). In winter, measured between 75 ± 11 376 24 Bq·m−3 (mean: 150 19 Bq m−3), whereas thoron ranged from below Lower Limit Detection (LLD) 166 10 66 8 while summer fell 50 305 (mean 115 18 m−3) LLD 122 m−3 48 6 Bq·m−3), respectively. The annual average effective dose estimated be 3.7 0.5...
Antigen-specific redirection of immune effector cells with chimeric antigen receptors (CARs) demonstrated high therapeutic potential for targeting cancers different origins. Beside CAR-T cells, natural killer (NK) represent promising alternative effectors that can be combined CAR technology. Unlike T primary NK and the cell line NK-92 applied as allogeneic off-the-shelf products a reduced risk toxicities. We previously established modular universal (UniCAR) platform which consists...
Abstract Impact assessment of building materials is a focused topic in the field radioecology. A radiological survey has conducted to monitor radioactivity most common Semnan Province, Iran, and assess radiation risk. Activity concentrations 226 Ra, 232 Th, 40 K were measured 29 samples including nine commonly used that collected from local suppliers manufacturers, using high purity germanium gamma-ray detector. The activity varied 6.7±1 43.6±9, 5.9±1 60±11, 28.5±3 1085±113 Bq kg −1 with...
The main goal of research presented in this paper was the material and radiological characterization high volume fly ash concrete (HVFAC) terms determination natural radionuclide content radon emanation exhalation coefficients. All samples were made with a between 50% 70% total amount cementitious materials from one coal burning power plant Serbia. Physical (fresh hardened density) mechanical properties (compressive strength, splitting tensile strength modulus elasticity) tested. (226Ra,...
This study provides a general observation of the status naturally occurring radioactive materials (NORMs) distribution in mining and industrial areas Ghana order to establish regional national data on NORMs. The includes radioactivity concentrations U-238, Th-232, K-40 soils for water Ra-226, Th-228, from various mining, oil, gas communities, as well sources used crop farming farmlands. average activity soil samples were found be 59 ± 16 Bq/kg, 48 15 286 57 respectively. concentration 1.62...
Radionuclide concentrations in environmental samples such as surface soils, plants and water were evaluated by high purity germanium detector measurements. The contribution rate of short half-life radionuclides 132I to the exposure dose residents was discussed from measured values. highest values 131I/137Cs activity ratio ranged 49 70 collected at Iwaki City which is located south F1-NPS. On other hand, 132I/131I same had lowest values, ranging 0.01 0.02. By assuming that atmosphere equal...
The study of staple food products is crucial to assure public safety and provides input for predictive dose assessment models. To further this goal, the activity concentrations, transfer factors, radiological hazards 226Ra, 232Th, 40K, 137Cs were studied ten pairs selected vegetables soils in Tien Le near Hanoi Vietnam. This first area Vietnamese vegetable samples. most popular diet selected, namely choy sum, crown daisy, lettuce, cabbage, Malabar spinach, beans, sweet potato, kohlrabi...
Abstract Background The European Union council has introduced the basic safety standards (EU-BSS) for protection against dangers arising from exposure to ionizing radiation by laying down a new radon reference level at workplaces. In this regard, all state members must establish national based on pre-defined requirements. After implanting directive 2013/59/Euratom members, challenges have been revealed mitigate appropriately in underground workplaces due exciting limitations (e.g.,...
The natural and artificial radioactivity in beach sediment sampled from the coastline of Ghana were analyzed using High Purity Germanium gamma ray detector. overall average activity concentrations 226Ra, 232Th, 40K 137Cs estimated to be 43 ± 6, 22 1, 393 74 8.4 0.5 Bqkg-1, respectively. Apart 226Ra mean measured radionuclides below world averages 32, 45, 412 18.2 Bqkg-1 concentration 109.8 was observed for one locations, which might due occurrence a nuclear incidence or other factors....
Prediction of areas with elevated natural radiation is fundamental for the prevention human exposure. Soil gas radon activity concentration and soil permeability are predictive parameters potential, which has great importance in where future urban development planned. In this study, equilibrium (C∞) (K) were estimated through application theoretical empirical models found literature. These apply properties as input parameters. Using already existing to predict potential an area would be...
