Որոշ գեղազարդ ծառերի տնկիների տերևների բետա-ռադիոակտիվությունն Արարատյան դաշտի և Դիլիջանի անտառային գոտու պայմաններում

Abstract

The specificities of the accumulation of the gross β-radioactivity and the controlled technogenic radionuclides (RN) 90Sr (T1/2=28.6 years) and 137Cs (T1/2=30.1 years) in leaves of several decorative tree saplings (sophora japonica, biota orientalis, cupressus sempervirens, fagus orientalis and carpinus caucasus) were studied in area of Institute of Hydroponics Problems (IHP) (zone of Armenian Nuclear Power Plant (ANPP) with radius of 30 km) and in Dilijan forest experimental station (DFES). It was revealed that the leaves of the saplings of sophora japonica and biota orientalis prevailed in gross β-radioactivity those of cupressus sempervirens in area of IHP and of fagus orientalis and carpinus caucasus in DFES. Therefore, decorative broad-leaved sophora japonica and conifer biota orientalis that were introduced into Armenia are suggested to be used in green building as natural accumulators of RN to create parks, green zones and forests. It may have important ecological value.
