Geschichte

The journal Radiochimica Acta was founded in 1962, under the patronage of the Nobel Laureate Otto Hahn, to cater for the publishing needs of the then fast expanding field of radiochemistry. In those days the radiochemists published their work in several different journals of chemistry and physics and had thus no platform of their own for technical communications. With the introduction of Radiochimica Acta a new era dawned for radiochemistry. Although published in Germany, right from its inception the journal aimed at inculating an international character and flavor. The international character has been maintained, continuously nurtured and further developed over its liefe of 50 years. Today all the articles are published in English language.

Abstract

The cross-sections for the 197 Au(p,pxn) 196-193 Au and 197 Au(p,xn) 197,195,193 Hg reactions within the proton energy range of 49.8–65.5 MeV were measured at the high-intensity proton linac facility (KOMAC) in Korea using the stacked-foil activation and off-line γ-ray spectrometric technique The proton beam intensity was determined based on the nat Cu(p,x) 62 Zn monitor reaction with the recommended cross-section accessed from the IAEA database library. The data gathered in the present work are compared with the available data from the literature, which agreed well with each other. In this study, the 197 Au(p,p5n) 193 Au reaction cross-section was measured for the first time. The data from the present work and existing literature were compared with the TALYS-1.9-based data taken from the TENDL-2019 library, which generally agreed well.

Abstract

Integral cross sections of the reactions 84 Sr( n , p ) 84 Rb, 86 Sr( n , p ) 86 Rb and 87 Sr( n , n ′) 87m Sr, over the fast neutron spectrum of a TRIGA reactor above 0.5 MeV, were measured for the first time. The results were used for integral tests of the evaluated excitation functions in the data libraries, ENDF/B-VIII.0, ROSFOND-2010, JEFF-3.3, JENDL-5 and TENDL-2021. The integral measurements are generally consistent with the integrated values within 12 %, except for a few cases. The two data libraries ENDF/B-VIII.0 and ROSFOND-2010 appear to need some improvement with regard to the reactions investigated in this work.

Abstract

A technological sample assaying 943 ppm U and about 0.97 % RE 2 O 3 in a mineralized ferruginous sandstone has been collected from Wadi Sedri area of southwestern Sinai. The XRD analysis has releaved the presence of uranium minerals namely; coffinite and sodium meta-autonite but the rare earths adsorbed on the clay minerals inter the ore sample. Leaching of uranium and rare earths from the studied sample is based on ferric sulfate salt. The relevant conditions e.g. (6 g/L ferric sulfate concentration, 1/5 S/L ratio, time 8 h, T = 80 °C and 7.5 g/L H 2 SO 4 concentration) of the ferric ion leaching for uranium and rare earths have been optimized. From the obtained leach liquor, the rare earths are precipitated as oxalates. This is followed by uranium recovery using anion exchange resin as impregnated Lewatite Monoplus M 500/Alamine 304. Therefore, highly pure products of uranium and rare earths have been obtained and chemically analyzed.

Abstract

Here, a novel method of synthesis of a sand-based adsorbent for radioactive Cs + ion removal is reported. Natural sand has been modified with cobalt hexacyanoferrate (CoHCF) using a simple and effective approach. The detailed physical–chemical characterization of the synthesized adsorbent is carried out using XRD, XPS, UV-visible, FT-IR, ICP-AES and Raman spectroscopy. Cs + ion batch adsorption studies were conducted radio-analytically, and the sorbent’s adsorption capability was observed to be ∼5 mg g −1 . The batch studies revealed that Cs + ion was selectively adsorbed throughout a broad pH range of 1–10. The rate-controlling steps in the adsorption process, according to kinetic studies, are film diffusion and intraparticular diffusion and the adsorption process follows a second-order kinetics.

Separation of ^71,72As from alpha-particle induced reaction on gallium oxide target using naturally occurring alkaloid caffeine

Abstract

Gallium oxide target was irradiated with 46 MeV alpha-particle beam, which produced 71,72 As and 67 Ga radioisotopes in the matrix. Separation of radio-arsenics from the bulk gallium target was carried out by caffeine, a nature-resourced reagent, extracted from black tea leaves. 71,72 As radionuclides were preferentially attached with caffeine and precipitated with caffeine in 2 M Na 2 SO 4 solution as caffeine was insoluble in aqueous medium under this condition. With increase in weight of caffeine, extraction of 71,72 As and bulk gallium significantly increased. Bulk Ga along with 67 Ga remained in the supernatant. Geometry optimization of caffeine–metal complex was carried out by theoretical computational analysis. DFT calculation corroborated with the experimental findings where As 3+ preferentially binds with caffeine in presence of gallium and arsenic. As evidenced by the short As–O and As–N distances, the high binding energies are a result of the metal ion’s strong binding to the carbonyl and nitrogen centres, whereas no such result could be obtained in case of bulk gallium.

Abstract

Agaricus bisporus mushrooms contain various bioactive substances, the current study aimed to evaluate the effects of gamma-irradiation (1.5, and 2.0 kGy) and essential oils (EOs) fumigation treatments including; geranium (60, and 80 μL L −1 ) as well as lemongrass (40, and 60 μL L −1 ) on quality characteristics (color, weight loss, firmness), and microbial properties, as well as total and reducing sugars of mushrooms at 4 °C during storage for 12 days. It was found that 40 μL L −1 lemongrass (L1) showed the highest L * after 12 days of storage so, it gave the greatest impact on reducing browning of mushrooms. Geranium oil (G1) recorded the least increase in weight-loss (3.01 %) after 12 days of storage. Otherwise, the firmness was also significantly inceased in the EOs (60 μL L −1 of geranium and 40 μL L −1 of lemongrass) samples compared to the controls and gamma-rays. The EOs achieved slight increases in TSS% compared with other treatments. Also, total sugar content in all treatments showed an overall reduction with storage time. Gamma-irradiation (1.5, and 2.0 kGy) was more efficient in inhibiting the development of mesophilic and psychrophilic count. While, lemongrass treatment (L2) has the lowest count of fungi at the end of storage (0.5 log10 CFU g −1 ). The current findings suggest that and EOs (geranium & lemongrass) and gamma-irradiation are a promise process for maintaining the quality of A. bisporus through refrigeration preservation.

Abstract

GeO 2 -doped magnesium-telluroborate transparent glasses were synthesized in the current investigation using the traditional melt-quench procedure. XRD and FT-IR were used to examine the glasses’ structural properties. Following the measurement of the density, various physical parameters (including oxygen molar volume, oxygen packing density, etc.) were estimated and examined. From the FTIR results, one can deduce that clear structural alterations are seen which support the presence and conversion of BO 3 and BO 4 units. This is a result of the glass network forming more GeO 4 , TeO 4 , and BO 4 units, which means that decreased NBO is forming, and more stiff networks are forming as a result. The increase in the overall stretching force constant of the glasses may also have an impact on the elastic moduli. The optical parameters were studied as optical energy band gap, Urbach energy and refractive index of the fabricated glass. According to the HVL data, the current glasses have a significant ability to lessen the intensity of gamma rays with lower energy. The glass with a small amount of GeO 2 has a high HVL, whereas the glass with a higher amount of GeO 2 has a lower HVL, as shown by the HVL data. The G5 glass demonstrated its superiority as a shielding glass over the other glass samples (G1–G4).
