Gruntinio vandens lygių ir tričio tūrinio aktyvumo sezoninė kaita Maišiagalos radioaktyviųjų atliekų specialiajame punkte

Abstract

In the territory of special point there are 8 wells to control likely radioactive waste migration from the pile. Stratification depth of ground water is adjusting by the distance from the top of the ground to the level of water in every well. By height of ground water its flow wav is adjusting. The level of ground water differs in every season. It abates most in autumn and floods in spring. Pore water and ground Mater is the main agent which transfers radionuclides. The past investigations showed that H circulates out of the pile, but it is registered only in fourth and fifth wells. Volumetric activity of the H in the water of wells depends on the flow of the ground water from which side and how much polluted ground Mater gets into pipe of the well. It is credible that less tritium gets to the ground Mater, which is underneath and its volumetric activitv is lower.
