At the experimental plot of Weissfluhjoch in Switzerland, 2,540 m a.s.l., tritium, deuterium and oxygen-18 have been used to study exchange processes during the build-up and ablation of the snow cover as well as the hydrological balance. Selected results from the period 1971-1979 are presented. The varying isotope concentration of the respective snow layers reveal a mass exchange between the percolating melt water and the snowpack, influencing the isotope composition of the outflow from a snow lysimeter. A correlation between the isotope concentrations in the snow cover and meltwater has been established. The enrichment of meltwater in stable isotopes enables the evaporation to be calculated independently from the hydrological measurements. Parallel tritium data point to a surprisingly high exchange between the snow surface and air moisture.

The main problems of overhead and cable transmission lines with voltage >=110 kV electric and magnetic fields general public protection are presented. It is shown that it is necessary to develop regulatory requirements for these lines’ sanitary protection zones organization, taking into account the magnetic field component, because its possible health risk factor, up to carcinogenic.

Introduction. Sanitary legislation of the Russian Federation provides for the organization of sanitary protection zones of industrial enterprises located in the industrial hub. However, the justification procedure, establishing and monitoring boundaries of a single sanitary zones not fully resolved. This determines the practice of organization by economic entities of individual zones separating production from residential development. This situation complicates the adequate assessment of real pollution, as well as the reasonable development of programs (plans) of environmental measures. Identification of the sources that create poor air quality and public health risks is becoming extremely problematic.The aim of the study is to develop and test recommendations for the organization and methodological support of the design of a single sanitary protection zone of a group of enterprises in the current urban development.Materials and methods. The object of the study is an industrial hub formed by 5 industrial enterprises and located on the territory of a large urban settlement with a population of more than 450 thousand people. The city administration carried out a number of organizational measures that ensured the simultaneous inventory of emissions of enterprises and the design of the general sanitary zone of the industrial complex. The design work was carried out in full accordance with the current regulatory framework.Results. The verified unified database of 102 sources of chemical emissions and 113 sources of noise provided the possibility of summary calculations and obtaining the most correct results for surface concentrations in the zone of influence of the industrial hub. The program of quality control of atmospheric air defining the contribution of each economic subject to carrying out researches is formed. This made it possible to ensure the control of all priority contaminants at the outer border of the sanitary zone and reduce the costs of each separate economic entity. Zones of responsibility of each enterprise within borders of a uniform sanitary zone for tasks of maintenance of the standard maintenance of the territory are allocated.Conclusions. The obtained results confirmed the feasibility of designing unified sanitary protection zones for economic entities located in the industrial hub.

The article analyzes the possible risks that can arise when firing artillery and rocket launches. The disadvantages of the method of calculating the protection zones are identified, which taking into account will reduce the likelihood of the occurrence of abnormal situations, which can lead to tragic consequences and damage to objects adjacent to the boundary of the testing ground. Additions to the procedure for determining the protection zones of the test site in the interests of RVIA are proposed and the specified, correct sizes of these zones are provided. Development of rocket troops and artillery (RTaA) of the Armed Forces (AF) of Ukraine is impossible without a permanent improvement and modernisation of types of armament and ammunition to them, development of the new artillery systems and their ground tests. During realization of ground tests of types of armament and military technique (WME) of RTaA firing of artillery and starting of rockets is accompanied by errors or wrong acts of WME attendant and personnel or extraneous persons, the consequences of that must be envisaged, and the risk of their origin is Analysis of the battle firing, including during realization of anti-terror operation and operation of the incorporated forces on east of Ukraine row of ground tests of standards of WME RTaA test if possibility of origin of nonpermanent near-accidents during application of armament of RtaA as a result of rejection of trajectory of flight of projectile (mines) by the direction and distance from the expected targets. Mostly it happens through untaking into account of maximal rejections of meteorological and ballistic terms of firing from tabular or errors in calculations, wrong acquisition of charge, error at aiming of fighting machines, cannons, mortars. There for practice of the battle firing needs taking into account of these errors, that will give an opportunity consider ably to promo test rength security at application of armament of RAaT during testing of standards of WME. Thus, in the article certainly and possible risks that can arise up during realization of firing of artillery and starting of rockets are analysed, related to the lacks of existent methodology of realization of calculations in relation to providing of safety measures during the tests of WME RtaA. Suggestions are brought in, in relation to the improvement of methodology of realization of calculations of sizes of protective zones, that unlike existing more in detail take into account maximal deviations of terms of firing from tabular values. These suggestions for providing of safety measures it will be allowed to decrease probability of origin of situations, that can result in tragic consequences and to causing of damages to the objects that fit closely to the limits of training field. Anoffer adding to the order of determination of protective zones and given specified sizes of the sezones have an important practical value at determination of possibilities of grounds and providing of safety of testing and battle firing (starting) of RtaA.
