Background: The activity concentrations of some radionuclides in soil samples collected from 20 locations in 8 major towns in Oyo State, Southwestern Nigeria have been determined by gamma-ray spectrometry technique. Materials and Methods: The activity concentrations were determined using high-purity germanium (HPGe) detector (Canberra Industries Inc.). The outdoor absorbed dose rates in air at ...

Background: Ionizing radiation is present in all environment of the Earth’s surface, beneath the Earth and in the atmosphere. Human beings are exposed to external radiation from their surroundings naturally and also to internal radiation from food, water and air they consume. Then, it is important to measure and develop knowledge about radiation. Objective: This study is designed to evalu...

background: the exposure of human being to ionize radiation from natural sources is a continuing, inescapable feature of life on earth. direct measurement of absorbed dose rates in air has been carried out in many countries of the world during the last few decades. such investigations can be useful for assessment of public dose rates, the performance of epidemiological studies, and keeping refe...

Background and Objectives: Gamma rays, the most energetic photons within the any other wave in the electromagnetic spectrum, pose enough energy to form charged particles and adversely affect human health. Provided that the external exposure of human beings to natural environmental gamma radiation normally exceeds that from all man-made sources combined, environmental gamma dose rate and corresp...

ژورنال: سلامت و محیط زیست 2019

Background and Objective: Humans are always exposed to ionizing radiation that could potentially have harmful effects. The aim of this study was to evaluate the background gamma dose rate, the estimated annual effective dose, and the excess cancer risk assessment in Dargaz. Materials and Methods: This study was a cross sectional study which was conducted in January- March and July – September ...

Background: Background gamma radiation levels vary in different locations and depended on many factors such as radiation properties of soil, building materials as well as construction types which human lives on it. People are always exposed to ionizing radiation, which could badly influence their health. The aim of this study was to evaluate the background gamma-ray dose rate and the estimated ...
