AbstractThe present investigation assessed the influence of physico-chemical parameters on natural radionuclides in the Kollam coastal belt which is a high background radiation region. The activity concentration of40K,226Ra, and232Th in sand samples has been measured using Flat type 5" × 5" NaI detector to assess the influence of physico —chemical parameters in natural radionuclides. The physico-chemical parameters such as moisture content, pH, electrical conductivity, organic matter content, and particle size distribution percentage (silt, clay, and sand) of sand samples were determined using standard pr...

Facile fabrication of new bioadsorbents from Moringa oleifera and alginate for efficient removal of uranium(VI)
This article presents the first study on the use of alginate and moringa as an effective adsorbent for uranium treatment under various conditions. A new method of preparing adsorbents was used by addingMoringa oleifera seeds (MOS) to alginate through simple grafting. The resulting beads have a heterogeneous, sponge-like structure that is reversible. The adsorbents were tested for their ability to remove uranium ions from water and showed excellent efficiency with an adsorption capacity of 443.60 mg/g for alginate-PEI-MOS and 341.38 mg/g for alginate-Glu-MOS. Additionally, these adsorbents showed an interesting rate of s...

Selection of simulants for separating radionuclides of transplutonium and rare-earth elements via displacement complexing chromatography with DTPA-based eluents
AbstractThe paper presents data on selecting curium and americium simulants for the lab-scale development of a displacement complexing chromatography-based separation technique. Being eluted with the eluents based on DTPA and a mixture of DTPA and citric acid, the rare earth element holmium behaves exactly as curium and terbium —as americium. Conversely, the tracer additives of transplutonium radionuclides are a perfect option for rare earth separation studies. (Source: Journal of Radioanalytical and Nuclear Chemistry)

Microwave sintering for rapid treatment of simulated Nd3+ and Sr2+ radioactive contaminated soil: exploring the influence of Nd:Sr mass ratio and mechanism
This study achieves the successful immobilization of simulated alpha- and beta-emitting radionuclides (Nd3+ and Sr2+, respectively) by incorporating them into a glass matrix through Nd2O3/SrSO4 (Nd/Sr). Varying mixture concentrations (5 –30 wt% with mass ratios Nd:Sr varied from 10:1 to 1:10) in simulated radioactive soils were subjected to microwave sintering at 1500 °C for 0.5 h. Comprehensive assessments, including X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, scanning electron microscopy (SEM), and energy dispersive X-ray spectrometry (EDS), confirm the vitrification process’s efficacy. T...

Roles of Junglas nigra husk extract microelements as radioprotectors: an in vivo model using 99mTc-radiopharmaceuticals
AbstractThe aim of this work was to analyze the multi-elemental composition of the extracts ofJ. nigra husk, with an assessment of the possible influence of their microelements on biochemical, toxicological and radioprotective effects of in rats exposed to radiation from99mTc-radiopharmaceuticals. The elements in extract were quantified: microelements (Zn>Al>Se>Cu>Sr>Cr>Ni>Mn>Ba>I>V) and toxic-elements (Pb>Hg>Cd>As). The use of extract in rats showed no clinical evidence of toxicity in terms of biochemical parameters. The results showed significant alteration in the organs accumulatio...

Evaluation of natural radioactivity levels and related radiological hazards in marine sediment samples taken from Ahanta West in the Gulf of Guinea, Ghana
AbstractA baseline study was carried out to determine the activity concentrations of238U,232Th-decay series and40K in marine sediment. Surface sediments were taken from 29 sample stations. The average activity concentrations(Bq kg−1) of238U (20.2),232Th (7.4) and40K (70.0) were below the world average with an annual effective dose (43.07 µSv y−1) unlikely to pose significant radiological risk. The ERICA tool application confirmed the potential dose rate to marine biota from radioactivity in sediments is unlikely to pose an appreciable risk. The findings offer a crucial radiological risk profile characteristic tha...

Rapid vitrification of simulated HLLW by ultra-high power laser
AbstractIt is essential to treat high-level liquid waste (HLLW) in a secure and effective manner. As a result, we first propose rapid vitrification of simulated HLLW using an ultra-high power laser. First, a cured body with a mass of 24.4 kg was obtained by using ultra-high power laser sintering. Subsequently, four different locations of the curing body were tested and the measured performance indicators were all in accordance with the regulations. This demonstrates the potential of ultra-high power lasers in HLLW glass curing proc esses. (Source: Journal of Radioanalytical and Nuclear Chemistry)

Simultaneous diffusion of Re(VII) and Se(IV) in compacted Tamusu clay by capillary method
AbstractThis paper presents the first laboratory-based, simultaneous diffusion experiments of Re(VII) and Se(IV) in Tamusu (TMS) clay, using the capillary method. We determined diffusion coefficients (Da) and adsorption values (Kd) for these nuclides under varying clay compaction densities, solution pH values, ionic strengths, and in the presence of humic acid (HA). The results indicated rapid acquisition of diffusion data, theDa values predominantly ranging from 10−9 m2/s to 10−10 m2/s, and weak adsorption for both Re(VII) and Se(IV). While the presence of HA augmented theDa andKd values for Re(VII) and Se(IV) diff...

Numerical study on the characterization of NdFeB permanent magnets with fast-neutrons induced (n, n ′γ) reactions
AbstractThe potential of prompt gamma analysis based on inelastic scattering of 2.5 MeV neutrons for a rapid characterization of NdFeB permanent magnets is investigated by means of numerical simulations using an HPGe detector and a CZT detector-array. The results show that rapid assay of a 42 g magnet can be achieved in some minutes when the neutron flux at sample position is ab out 1.6 × 109 cm−2 s−1 and the detector count rate limited to 500 kcps. Such a high neutron flux could be delivered by a compact 5 MeV proton accelerator with a thick beryllium target for neutron production through the9Be(p,xn)9Be....

Assessment of radon (Rn-222) activity and associated doses to estimate ELCR and LLC in groundwater in Ranchi district, Jharkhand, India
AbstractThe present study deals with an overview of the distribution of radon (Rn-222) concentration in the groundwater and its associated annual effective doses in Ranchi district, Jharkhand, India. The samples were collected from deep tube-wells and the Rn-222 concentration was measured in the collected samples using an ionization chamber type radon monitor AlphaGUARD. The measured Rn-222 activities in few groundwater samples are found beyond 100 Bq/L. The total annual effective dose (AED) has been estimated for three different age groups (adults, children and infants); and the result shows that the total AED of 72.17%...

Time evolution of rejected, coincidence spectra, registered on germanium gamma spectrometers with muon-sensitive veto shields
AbstractThis paper presents the effects of background reduction with anticoincidence logical condition between the sum of muon-sensitive large scintillator veto detectors and a germanium detector as well as the time evolution of rejected, muon-induced coincidence gamma spectra. A special attention is paid to neutron effects. The digital event-by-event registration used for data acquisition opens possibilities to study in an off-line mode the variety of effects related to the time structure of all signals registered by detectors. In our laboratory currently we use two such systems with in-house written software Veto for off...

Radiation dose assessment of thorium-containing gas mantle in consideration of usage status in Republic of Korea
This study developed predictable exposure scenarios for thorium-containing gas mantles throughout their life cycle, considering their usage status in the Republic of Korea, and assessed the radiation dose for each scenario. Our results showed that radiation doses in various scenarios, including transport, distribution, usage, and disposal, as well as in low-probability accident scenarios, consistently remained below the regulatory exemption standards set by the International Atomic Energy Agency. Therefore, we concluded that the exemption regulation for the gas mantle is valid under current circumstances in the ROK. (Sourc...
