Impact of Environmental Radiation on the Incidence of Cancer and Birth Defects in Regions with High Natural Radioactivity.

Four regions of high natural radioactivity were selected to assess radionuclide levels in rocks and soils, ambient radiation doses, radon exhalation from the ground, and radon concentrations in the air. The regions have different geochemical characteristics and radioactivity levels, which modulate the radiation exposure of local populations. Combining radiometric data with data from regional health statistics on non-infectious diseases, a statistically significant positive correlation was found between radiation exposure and the incidence of cancer and birth defects.

Influence of local geological data and geographical parameters to assess regional health impact in LCA. Tomsk oblast', Russian Federation application case.

The research paper is aimed to modify the human health impact assessment of Cr in soils. The current article presents the input of several critical parameters for the human health Impact Score (IS) assessment in soils. The modification of the IS is derived using geological data - results of neutron activation analysis of soils are used in the IS calculation; research area is divided using the watersheds and population size and density.

Poplar tree (Populus balsamifera L.) as indicator of mercury emission from a point source.

The article provides original data on the ecological and geochemical characteristics of the distribution of Hg in the leaves and annual rings of balsam poplar (P. balsamifera L.) in the zone of influence of lithium production (Novosibirsk).

Landscape REE anomalies and the cause of geophagy in wild animals at kudurs (mineral salt licks) in the Sikhote-Alin (Primorsky Krai, Russia).

To test the "rare earth" hypothesis of geophagy, geological and hydrogeochemical studies unparalleled anywhere in the world were carried out at kudurs (salt licks) in two districts in the Primorsky Krai, Russia. The mineral and chemical compositions of geophagic earth consumed by animals, the chemical composition of surface waters and vegetation, and the chemical composition of biological tissues of red deer (Cervus elaphus) were studied in this research. It was found that ultra-fresh surface and fontinal waters in the studied areas contain anomalously high concentrations of rare earth elements (REE), the sums of which exceeded the average values in the Primorsky Krai and worldwide by tenfold, and more.

Rare earth elements in poplar leaves as indicators of geological environment and technogenesis.

Background and anomalous rare earth element (RЕЕ) concentrations in poplar (Populus spp.) leaves in urban areas of Siberia, Russian Far East, and Kazakhstan were determined. Regions with the highest RЕЕ levels were identified.
