Activation analysis of plants within regions of geothermal resource development

摘要: Environmental effects on plants caused by geothermal resource development were studied. Neutron activation method was found most suitable for this kind of multi-element analysis, and 24 elements could be identified determined without any chemical separation. When the amounts detected in plotted against distance from source well, clear correlations sould observed Na, Cl, Rb, Cs, As Sb. Those turned out to especially concentrated hot water. From present studies it concluded that growing within radius 300 400 meters well affected pollutants carried over mist particles.
