AB  - Using ionizing radiation in treating waste sludge from a drinking water treatment plant is a well-known technique. Sludge treated with ionizing radiation can be used as fertilizer in agriculture. In this paper, the effects of aging on the physicochemical characteristics, the content of microorganisms, molds, acrylamide, heavy metal concentration, and total nutrient content in waste sludge treated with e-beam and gamma irradiation were investigated. The possibility of using treated sludge as a fertilizer in agriculture was evaluated. It has been shown that the content of acrylamide in treated sludge after 15 months of storage does not exceed the limits for sludge to be used as fertilizer. If the sludge is stored in closed bags in a dark place, aging does not increase total microorganisms and molds. The research also showed that the sludge's physicochemical characteristics treated in this way do not decrease under the influence of aging. Finally, it has been shown that aging does not change the concentration of heavy metals and total nutrients in sludge treated by ionizing irradiation.

AB  - An increasing production of drinking water and a significant amount of waste in the form of treated sludge can lead to a serious environmental problem. The high organic content in the sludge, together with the high summer temperatures, results in the enhanced activity of sludge microorganisms, causing severe can cause serious biological pollution. Also, there is a danger due to the potential presence of polyacrylamide, which is very harmful to human health and the environment. In this paper, the influence of different types of ionizing radiation (gamma and e-beam) on microorganisms inactivation in waste sludge from drinking water treatment plants was investigated. The content of heavy metals and polyacrylamide before and after irradiation was determined. It was concluded that the content of heavy metals in the waste sludge obtained from the drinking water treatment plant is significantly lower than the limit values. The concentration of acrylamide, both before and after irradiation, was limit value for sludge to be used as fertilizer. It was found that the dose of 25 kGy inactivates all pathogens in all samples collected directly after coagulation, flocculation, and sedimentation and that the dose of 10 kGy is sufficient to inactivate all pathogens from dewatered samples previously treated with lime. In both cases, the number of microorganisms decreases sharply with increasing radiation dose.

AB  - The distribution of the absorbed dose within the irradiated product is a complex function of the product density and homogeneity, the position and shape of the radiation source, as well as the design of the irradiator. In this paper, detailed mapping of absorbed radiation doses in products of different density: gauze, plastic, and soil, is performed. Positions of minimum and maximum absorbed radiation dose were determined, and the homogeneity of irradiation of products was calculated using the ethanol-monochlorobenzene oscillotitrator dosimetry system. © 2020, Vinca Inst Nuclear Sci.

AB  - Ultraviolet absorption spectra of three isomeric pyridinecarboxylic acids (picolinic, nicotinic, and isonicotinic acids) were measured in 18 various solvents, in the wavelength range from 200 to 400 nm. In order to analyze the solvent effect on the obtained absorption maxima, the ultraviolet absorption frequencies of the electronic transitions in the carbonyl group of the examined acids were correlated using a total solvatochromic equation in the forms nu(max) = nu(0) + s pi(*) + a alpha + b beta and nu(max) = nu(0) + s pi(*) + b beta, where nu(max) is the absorption frequency (1/nu(max)), pi(*) is a measure of the solvent polarity, alpha represents a scale of the solvent hydrogen bond donor acidity, and beta represents a scale of the solvent hydrogen bond acceptor basicity. Correlation of the spectroscopic data was carried out by means of multiple linear regression analysis. The effects of two different solvent types on the ultraviolet absorption maxima of the examined acids were compared and discussed.
