[en] A method was elaborated of selective extraction of metals (chromium and vanadium) from industrial wastes with possible re-use. Radionuclides were used for elaboration of a treatment of chromium effluents from electroplating workshops using ion exchange, eliminating the generation of a number of harmful sediments of heavy metals and recycling chromium in the production process. A hydrometallurgical technique was developed for extraction of vanadium from fly ash from power plants fired with heavy oil fractions. (author). 4 figs.,

[en] In the Institute of Nuclear Chemistry and Technology research on microbiological decontamination of medicinal herbs by irradiation has been carried out since 1996. It was shown that using ionizing radiation (a dose of 10 kGy) can obtain satisfactory results of microbiological decontamination of these products. The content of essential biologically active substances such as essential oils, flavonoids, glycosides, anthocyans, antra-compounds, poliphenoloacids, triterpene saponins, oleanosides and plants mucus did not change significantly after irradiation. Pharmacological activity of medicinal herbs has been found satisfactory after microbiological decontamination by irradiation

[en] The results of investigations the electron beam irradiation on the microbial contamination of selected blends and seasoning used in meat and milk industry are reported. The irradiation doses applied were not higher than 6.0 kGy. The level of microbial contamination were determined in irradiated and nonirradiated samples by standard methods routinely used. In addition, the usefulness of irradiated samples was examined by methods used for these products. The results obtained show that radiation can be successfully used foe decontamination of blends and seasoning, without changing the quality and applicability of the product. (author)

[en] The National Institute of Standards and Technology Gaitherburg USA has done in co-operation with INCT Warsaw the EPR dose measurements for two INCT ⁶⁰Co irradiators using l-alanine standard pellets as dosimeter medium. In the study the comparative EPR measurements of doses up to 40 kGy have been done using l-alanine powder with ⁶⁰Co source (reference to NIST standard) and EB linear accelerator, respectively. On the basis of this comparative study 5% correction factor for EB dose measurements has been adapted in the INCT Experimental Plant for Food Irradiation traceable to the dose estimations done with the Risoe calorimetric system

[en] There is an increasing demand for a powder soups and sauces composed with lyophylizated meat. Technology of lyophylization is not always accompanied by thermal treatment of raw materials. That is the reason the meat lyophylization process does not ensure as good microbiological quality as is required. Degree of microbiological decontamination and organoleptic properties of lyophilized meat were investigated after radiation treatment

[en] The results of investigations the electron beam irradiation on the microbial contamination of selected new generation cosmetics and raw products used in cosmetic industry are reported. The radiation doses applied were not higher than 6.0 kGy. The levels of microbial contamination were determined in irradiated and non-irradiated samples by standard methods routinely used. The results obtained show that radiation can be successfully used for decontamination of cosmetics and some of their raw materials, without changing the quality and applicability of the product.

[en] The irradiation of food and agriculture products have been used for several goals. That are: disinsectization, disinfection, sprout inhibition and retardation of mattering. In the frames of the national programme on the application of irradiation for food preservation and hygienization an experimental plant for electron beam processing has been established in INCT (Institute of Nuclear Chemistry and Technology). The pilot plant is equipped with a small research accelerator Pilot (10 MeV, 1 kW) and and industrial unit Elektronika (10 MeV, 10 kW). This allows both laboratory and full technological scale testing of the elaborated process to be conducted. The industrial unit is being equipped with e-/X conversion target, for high density products irradiation. On the basis of the research there were performed at different scientific institutions in Poland, health authorities have issued permissions for permanent treatment of spices, garlic, onions and temporary permissions for mushrooms, and potatoes. Dosimetric methods have been elaborated for the routine use at the plant. In the INCT laboratory methods for the control of e-/X treated food have been established. (author)

[en] The efficiency and palatability of two baits were studied to the control of crawling insects in urban areas: 'Cockroach Kill Gel' for control of cockroaches and Faratox B for control of ants. Ionizing energy was used in producing the baits. It was concluded, that after irradiation the palatability of Faratox B improved and palatability of Cockroach Kill Gel did not change

[en] Lecture shows comparison of food radiosterilization in Poland with selected countries in EU. The most popular commercial electron radiation sources are presented. Plant for Food Radiation Sterilization operating in the INCT (Inst. of Nuclear Chemistry and Technology) is discussed in details

[en] The research work on the microbiological decontamination of the medical herbs by electron beam was carried out. The seven samples of the herbs granules were irradiated at the doses 3, 6 and 10 kGy. It has been shown, that D10 values are varied in several samples after irradiation. Additional, research work, by gas chromatographic method, on the composition volatile oils (salvia, orange, peppermint and anise), after irradiation at the dose 4.4 and 8.8 kGy was carried out. It was not significant differences in the compositions between control and irradiated oils. (author). 12 figs, 2 tabs
