Проведение подобных работ тесно связано с задачей очистки водоемов 

 от радиозагрязнителей, а также с проблемой Вернадского о геохимической 

 роли живых организмов. 



SUMMARY 



It has been found that absorption of isotopes directly depends on the development 

 stage of insect: the highest concentration was found in larval stages, specially in the young 

 then in pupa and finally in adults. Some insects show a preference for different chemical 

 elements. Moreover some different species of insects absorb the same element to a different 

 extent, and on the other hand different elements are absorbed to a different extent 

 by the same insect species. Because the adsorption of radioactive materials from organism 

 was prooved to be very slow, the complexons became of greater importance, expecially 

 those of ethylendiamine and tetraacetate (EDTA), that support the resorbtion of different 

 isotopes from the studies organism.
