Monitoring the radionuclides content at highest water plants in anthropogenous habitats

In article results of monitoring researches on the contents and accumulation of natural and technogenic radionuclides in water plants growing in the river Small Kokshaga, flowing on the territory of Ioshkar-Ola city are reflected. It is noted that elodeya Canadian and pondweed, are characterized by the unequal maintenance of studied radioelements depending on sampling places. At the plants growing below dumping of sewage from OSK of Ioshkar-Ola city, level of natural radionuclides ( 40K, 226Ra, 232Th) content is noted by higher.
