INTRODUCTION The largest contribution for the global population exposure to ionizing radiation arises from natural sources, especially from radionuclides present in terrestrial crust. Certain human activities may eventually increase such exposure to significant levels, from the point of view of radiological protection (1, 2). The presence of natural radionuclides in building materials may lead ...

THE CHEMISTRY IN HUMAN HEALTH RISK ASSESSMENT DUE PESTICIDES EXPOSURE. Pesticides are widely used worldwide in urban and rural environments. Since most pesticides not selective for target species the concern about possible impacts on human health has increased workers exposed to these substances (occupational exposure) general population (environmental exposure). Epidemiological studies, vivo v...

Cohort studies of adverse reproductive effects of occupational exposures that compare the outcome of exposed pregnancies with non-exposed pregnancies among the same group of mothers (internal controls) and among a different group of mothers (external controls) have been reviewed. Confounding of the hypothesised associations by parental characteristics, the outcome of previous pregnancies, and o...

the aim of this cross-sectional study was to explore the association of crystalline silica aerosols exposure with malondialdehyde in blood serum and urinary neopterin and explore their potential as biomarkers of their external exposure. nonsmoking and healthy male glass sandblasters and control population were randomly selected for this study. all groups were monitored for their personal exposu...

Radiation effects on mortality from solid cancers other than lung, liver, and bone cancer in the Mayak worker cohort: 1948-2008. The cohort of Mayak Production Association (PA) workers in Russia offers a unique opportunity to study the effects of prolonged low dose rate external gamma exposures and exposure to plutonium in a working age population. We examined radiation effects on the risk of m...
