Introduction In this study, effective dose equivalent for the public due to internal exposure to 222radon (222Rn) was evaluated in three regions of Ramsar, a northern coastal city in Iran. Materials and Methods Measurements were carried out using a radon monitoring device. Outdoor and indoor radon concentrations were measured within 24 hours with an integration in...
INTRODUCTION Exposure to second-hand smoke (SHS) is a serious public health concern. The Indian smoke-free legislation 'Prohibition of Smoking in Public Places Rules, 2008' prohibits smoking in public places, including workplaces. OBJECTIVE To measure the status of compliance to legal provisions that protects the public against harms of SHS exposure, identifies the potential areas of violatio...
Milk would be contaminated with Aflatoxin M1 (AFM1) if it was obtained from lactating animal which fed with feedstuffs containing Aflatoxin B1 (AFB1). AFM1 is classified as group 2B, possibly carcinogenic to humans and exposure to AFM1 through milk consumption is a public concern. The purpose of this study was to determine the AFM1 exposure through liquid milk consumption for adult consumers in...

Weak microwave radiation (WMR) in our environment has raised health concerns in the public. Among those, communication frequencies are more than ever becoming widespread and their effects need thorough studies. A correct understanding of these effects in-vivo by in-vitro experiments shall preferentially use primary cells. In this study we compared non-modulated (CW) and modulated WMR exposure o...
High levels of air pollution are associated with adverse effects on public health. Pollutant concentrations are typically subject to a high spatial and temporal variability. To investigate and quantify potential relations between pollutant concentrations and health effects, e.g. cases of respiratory diseases, sophisticated geospatial tools and methods are required. Air pollutants are ubiquitous...
A number of papers dealing with the effects of modern, man-made electromagnetic fields (EMFs) on the immune system are summarized in the present review. EMFs disturb immune function through stimulation of various allergic and inflammatory responses, as well as effects on tissue repair processes. Such disturbances increase the risks for various diseases, including cancer. These and the EMF effec...
OBJECTIVE A substantial proportion of homes and automobiles serve as settings for environmental tobacco smoke (ETS) exposure, and many public settings that children frequent are still not smoke-free. Tobacco control efforts are attempting to increase smoking bans. The objective of this study was to describe the knowledge, attitudes, and practices of smokers and nonsmokers regarding smoking bans...
Fluoride is a naturally occurring contaminant in groundwater in Estonia. There are several regions in Estonia with fluoride contents in public water supplies as high as 7 mg/L. Long-term exposure to high-fluoride drinking water may have several adverse health effects, primarily dental fluorosis. The opportunities for exposure reduction rely highly on water treatment technologies. Since 2004 pub...
Introduction: Environmental tobacco smoke (ETS) exposure is a threat for health worldwide. The aim of this study was to determine the environmental tobacco smoke (ETS) exposure in people over 15 years old in Bandar Abbas, Iran. Methods: In this cross-sectional study a total of 387 subjects were selected by cluster sampling method. Data were collected by a questionnaire including demograph...
