Радиоэкологическая надежность локальных агроэкосистем

Abstract

An agroecosystem is an important source аor the subsequent transport of radionuclides from the environment to the man. The higher the factor of radiocapacity of the agroecosystem is the of the more reliable it is in understanding of the reliability of receipt radionuclides by people. Basing on the speed of migration, distribution and redistribution of the radionuclides-tracers-137Cs in the components of agroecosystem, and also on size of transition of 137Cs to all groups of the population, it is possible to expect the size of reliability given agroecosystem and to estimate the contribution of different components of agroecosystem in the formation of the doses exposed on the population. Depending on the quantity of radionuclides, which have dropped out on territory it is possible to apply different counter-measures, which efficiency depends on many factors (for example, such as types of soils, humidity, quantity of deposits and etc.) and to estimate their utility. The application of models and the theory of the reliability for research of ecological processes in different types of ecosystems is useful, as it allows estimating the basic characteristics and fundamental properties of ecosystems, by observation of the behaviour tracers - radionuclides 137Cs.
