Terrestrial Gamma-Radiation Field in Natural Environment

Natural Gamma Radiation in Primary Schools of Zanjan Province

Background: Environmental gamma ray refers to the gamma radiation from terrestrial sources and building materials. In enclosed spaces radiation can become a health hazard leading to potential increase in the rates of lung cancer. The goal of this study is to assess the exposure to natural gamma radiation of children in the schools of Zanjan province. Method:The natural gamma radiation was asse...

The Use of Gamma Ray Datato Definethe Natural Radiation Environment

Natural Gamma Radiation and Effective Annual Dose in Hot Springs in South Khorasan Province, Iran

Background and purpose:  Background radiation exists naturally in the environment and human has been always exposed to it. These rays can affect living creatures and cause chromosomal damage, and genetic and somatic diseases. Hot water springs are a major source of background radiation. This study aimed at investigating the absorbed dose of environmental gamma and determining the annual effecti...

Natural environmental gamma radiation exposure and prevalence of breast cancer in Poços de Caldas, MG, Brazil

Background: Environmental ionizing radiation has been associated with increased cancer risk by several studies.  The Brazilian city of Poços de Caldas, MG, seats on a huge deposit of uranium, which was until recently mined.  We performed a retrospective analysis of  310 cases of patients with breast cancer, who were exposed for at least ten years to different levels of ion...
