This work presents the natural radioactivity distribution of 21 surface soil samples taken in city Novi Sad, Serbia. The analysis for was performed using a gas low-level proportional counter gross alpha and beta activity, while specific activities radionuclides were determined HPGe detectors. activity 20 below minimum detectable concentration (MDC), 1 sample it 243 Bq kg-1; ranged from MDC (11 samples) to 566 kg-1. gamma spectrometry measurements showed naturally occurring 226Ra, 232Th, 40K,...

Plant-based protein matrices can be used for the formulation of delivery systems cinnamic acid. Pumpkin, pea and almond were dried complexes. The in varying amounts (1%, 2%, 5% 10%) whilst amount acid was maintained constant. obtained complexes analyzed by HPLC, DSC FTIR-ATR. highest determined on prepared lowest matrices, regardless their type. affinity adsorption pumpkin matrix. analysis revealed that caused an increase thermal stability matrix, while other two had opposite behavior....

Abstract As one of the oldest and most prominent universal monitoring organs quasi-judicial nature, UN Human Rights Committee has greatly contributed to development human rights regime. However, challenges remain. These relate particularly a lack implementation Committee’s decisions in national legal orders efficiency work Committee. From practitioner’s perspective, this article examines achievements shortcomings with special regard reporting individual complaint procedures. It considers...

The sorption properties of waste facade, brick, and asphalt sample towards Sr(II), Co(II), Ni(II) ions from single multicomponent solutions were investigated. highest capacity was found for ions, while the most effective sorbent facade. Simplex Centroid Mixture Design used in order to investigate processes with different composition as well competition between cations. Based on statistical analysis results, equations data modeling proposed. According observations, investigated solid matrices...

The modern way of life and aspiration for faster technological development creates increasing problems related to waste quantities management. Waste management is a complex process due the constant danger environment through pollution air, water soil as well human health. Lack quantity, composition location informations makes disposal categorization more difficult, its recycling or reuse. Industrialization society irrational usage natural resources increases amount waste, which need an...

The possibility of retaining Cs+ and Co2+ bound by immobilization processes in the cement matrix is defined as subject its investigation: formulation, water/cement ratio, amount waste, porosity such a structure. Implementing standard leaching method Hespe comparing different authors' results was achieved. Diffusion semi-empirical model were used to investigate transport phenomenon order predict level for long period time. Leaching ions under dynamic conditions immobilized decreases with...

The aim of the study was to evaluate potential risks radiation near abandoned uranium mines, tailing dumps, or deposits on Mountain Stara Planina, Serbia. For risk assessment several parameters were determined: radium equivalent activity, Raeq, external hazard index, Hex, gamma absorbed dose rate, D, annual effective background outdoor exposure, AEDoutdoor, and excess lifetime cancer risk, ELCR. Obtained results showed that all samples, except one, have Raeq value up two times higher than...

Utilization possibilities of solidified fractions industrial hazardous waste obtained by mixing with inert materials in construction were investigated. Waste mineral oils, water-hydrocarbon emulsions mixture, and filter cakes from the physico-chemical treatment wastewater generated washing patterned rollers for a printing machine, used as models solidification process. Investigation comprised preparation concrete asphalt mixtures further testing. The powder was analyzed regarding...

The utilization of construction and demolition debris in industrial wastewater treatment by sorption Co2+ Ni2+ ions was investigated. Selected waste composites are cost-effective locally available, still their characteristics application not sufficiently samples concrete, facade, ceramic materials, asphalt were characterized terms mineral surface composition, radioactivity, stability at different pH values, as well values suspension filtrate electrical conductivity the filtrate. capacities...

Preovlađujući diskurs o energetici u savremenoj eri naglašava klimatske promene i energetsku bezbednost kao najvažnije zabrinutosti. Dok su obnovljivi izvori energije (OIE) zavisni od geografskih klimatskih uslova, postavljajući izazove što diskontinuirana dostupnost zahtevi za okupiranjem velikih površina zemljišta, nuklearna energija predstavlja obećavajuću alternativa. Međutim, putanja ka nuklearnoj energiji vidu čiste je zamagljena strahovima javnosti državnim propisima politikama,...

Minerals and raw materials contain naturally occurred radionuclides from 238U, 232Th decay series as well 40K. These elements have always been present in the Earth’s crust atmosphere. Industry uses many different that occurring radioactive (NORM). industries include: coal industry, oil gas metal mining, mineral sands, fertiliser (phosphate) building recycling. The emissions of to air water lead eventual exposure humans. From reason, knowing exposures general public arising environment...

Women from ethnic, national, religious, and cultural minorities face distinct legal challenges in their struggle for gender equality. They are at constant risk of multiple discrimination as minority women, particularly with regard to identity religious rights. This is evident matters inheritance, wearing items public, issues related sexual domestic violence. International approaches this problem fragmented, the ECtHR, UN HRC, other international human rights bodies taking different...

Seven herbal teas used in Serbia were analyzed to determine gross alpha and beta natural radioactivity. In all samples, the ranged from 149 Bq/kg Melissa leaf sample 193 Bilberry Leaf. The 272 Leaf 1091 ± 117 Burdock sample.

Studies on the radiation level and radionuclide concentration in foodstuffs are available literature; however, information content of radionuclides coffee is very scarce. Hence, this research was carried out to determination gross alpha beta activity for alpha− beta−emitting coffee. A planned comprehensive study dedicated determine radioactivity different Serbian market using a low gas proportional counter. The values all measured samples were below detection limit. average value 384 Bq/kg.
