The work is devoted to solving the problem of radon mapping of the Taman peninsula as a problem of interaction between the region’s ecosystems and population. An express method of calculating the radon volumetric activity for decay energy of secondary products designed and implemented. Data of the 3-year's field investigations allowed us to plot the map of distribution of radon volumetric activity in the coastal zone of the Azov and Black seas of the Taman Peninsula, as well as over its surface. Some potentially dangerous territory identified. Average values of radon volumetric activity determined in the zones of tectonic disturbances and for the main territory of the Taman.

An intensive abrasion of the coast of the most popular Lithuanian Palanga health‐resort necessitates consideration of the most effective ways of its stabilization. Based on the data of field investigations and literary sources, the possibilities of Palanga coastal zone regeneration using the sand dredged from the entrance channel of Klaipeda port are considered. Based on the current geodynamic trends of Palanga coastal zone and results obtained by comparative analysis of granulometric composition of sediments dredged from the entrance channel of Klaipeda Port, the optimal possibilities of using the dredged sand for coast regeneration were determined. It was established that formation of underwater sandbar (analogue of natural bar) in the surf zone of coastal sector between the Palanga Pier and Birute Mount at a depth of 3 m would be the best solution for coast regeneration under the current conditions. Santrauka Intensyvi populiariausio Lietuvoje Palangos kurorto jūros kranto arda verčia ieškoti efektyviu kranto stabilizavimo metodu. Pastaruoju metu (2003–2008 m.) atlikti apsauginio paplūdimio kopagūbrio tvirtinimo bei paplūdimio sanašu atsargu papildymo Palangos rekreacineje zonoje darbai leme tik trumpalaiki kranto apsaugos efekta. Straipsnyje, remiantis natūriniu tyrimu bei literatūros duomenimis, ivertintos smelio, iškasamo iš Klaipedos iplaukos kanalo, naudojimo Palangos kranto zonai regeneruoti galimybes. Atsižvelgus i dabartines Palangos kranto zonos geodinamines tendencijas bei atlikus šio ruožo ir iškasamo iš Klaipedos uosto iplaukos kanalo biriu sanašu sudeties lyginamaja analize, nustatytos optimalios iškasamo smelio panaudojimo kranto zonai regeneruoti galimybes. Esant dabartinei situacijai efektyviausias kranto zonos regeneravimo būdas ‐ povandeninio volo (gamtinio sekliaus analogo) 3 m gylyje kranto ruožo tarp Palangos tilto ir Birutes kalno gožos zonoje formavimas. Резюме Интенсивный размыв морского берега в рекреационной зоне самого популярного курорта Литвы – Палангe вынуждает искать эффективные способы его стабилизации. Выполненные за последнее время (2003–2008 гг.) работы по укреплению дюнного вала и попытка пополнить пляж наносами в береговой зоне г. Паланги дали лишь кратковременный берегозащитный эффект. На основе натурных данных в статье оценены возможности использования для регенерации береговой зоны Паланги песка, выкапываемого из подвходного канала порта Клайпеды. Учитывая полученные результаты исследований современных геодинамических тенденций береговой зоны г. Паланги, состав наносов подвходного канала порта г. Клайпеды и изучаемого участка, установлены оптимальные возможности использования добываемого песка для стабилизации береговой зоны г. Паланги. Установлено, что при нынешней ситуации самым эффективным способом регенерации береговой зоны является формирование подводного вала (аналог природного) в прибойной зоне на глубине 3 метров на участке между Палангским мостом и мысом горы Бируте.

The qualitative and quantitative composition of planktonic societies in the southern part of the Kerch Strait in the coastal zone of the Taman Peninsula in September 2018 was studied. The phytoplankton consisted of 84 species, the average values of its abundance and biomass were 106 ± 22 million cells/m3 and 227 ± 32 mg/m3 respectively. The leading role in its composition was played by Nitzschia tenuirostris (by number) and Proboscia alata (by biomass). Zooplankton was represented by 24 species and taxa, its quantitative indicators were 32.5 ± 3.3 thousand individuals/m3 and 0.24 ± 0.02 g/m3 respectively. The copepod Oithona davisae dominated in terms of numbers, Oithona davisae, Parasagitta setosa, Decapoda and Cirripedia larvae dominated in biomass. An analysis of the composition and structure of planktonic communities showed their low structural diversity and evenness, as well as a stress state due to natural and anthropogenic factors. A close trophic relationship was revealed between the quantitative indicators of copepods and phytoplankton, excluding the dominant microalgae, the shape and size of which prevent them from being grazed.

The approach to creating standard means for reproducing units of volumetric activity of radon and thoron and flux density of radon from the soil surface is described based on the physical principles of reproducing these units of quantities and using as technical means for reproducing bubblers with a radioactive solution of radium salt, reference capacities of known volume, emanation chambers for generation of a toron, a gamma spectrometer with a semiconductor detector from highly pure germanium and radon radiometers. Reproduction consists in the physical realization of units in accordance with their definition as applied to the formation of radon and thoron in the radioactive rows of radium and thorium. The proposed approach will allow to determine the structural, structural and other technical solutions of standard measuring instruments, as well as specific techniques and methods of working with them. The creation of standard tools and technologies for reproducing units of volumetric activity of radon and thoron and the density of radon flux from the soil surface will ensure the unity and reliability of measurements in the field of ionizing radiation, traceability of units and bringing the characteristics of national standards in line with world achievements.
