The starting point of the Spanish experience in the study of High Background Radiation Areas is the development of a nationwide indoor radon survey carried out in 1988. This campaign, belonging to the first Spanish Radon Framework, consisted of approximately 2000 indoor radon measurements which represented a valuable basis to face rigorously the radon issue in Spain. Together but indepently fro...
abstractbackground: there are relatively rich uranium mines in regions of saghand and bafgh in yazd province. this survey was carried out to provide a map of ambient gamma radiation of yazd province and the probable effects of the existence of these mines on background radiation dose rates.materials and methods: the measurements of the outdoor and indoor–environmental exposures (including cosmi...
background: the effect of natural background radiation on health is still controversial. however, it is clear that it depends on the dose received by the population. the estimation of external natural background gamma rays received by the population of caspian coastal provinces in the northern part of iran was the main goal of this study. materials and methods: gamma rays was measured using cal...
Background: In some areas of Ramsar, a city in northern Iran, residents receive a much higher annual radiation exposure than is permitted for radiation workers. Induction of adaptive response in residents of Ramsar has been reported previously. In this study induction of such a response in short term exposure to high background levels of gamma radiation is investigated. Materials and M...
Backgrounds and Objectives: Due to importance of ionizing radiation on human health, many studies have been performed to measure the background gamma radiation all around the world as well as some cities in lran. According to this fact that everybody spends almost 80% of his time in indoor areas, this study was carried out to measure the amount of background gamma radiation in indoor areas in Z...
abstract background and purpose: people are always exposed to ionizing radiation, which could badly influence their health. the degree of these influences depends on the level of radiations. in this study the dose of indoor gamma radiation was assessed using rds-110 multi-purpose survey meter. materials and methods: to determine the dose rate of indoor radiations in cities of hamedan province f...
today, nuclear medicine has rapidly been developed so that in some cases, plays a unique role in diagnosis but unfortunalty in spite of diagnostic and therapeutic advantages, the term “nuclear” can induce worries in patients and society. in this article, base on new documents, we intend to show that this worries has no scientific basis. to produce a realistic view, regarding to radiation protec...
Background and Objective: Due to importance of ionizing radiation on human health, many studies have been performed to measure the background gamma radiation all around the world as well as some cities in lran. This study was carried out to measure the amount of background gamma radiation in outdoor areas in different seasons in Zanjan to determine the annual effective dose of the city resident...
The main objective of this paper is to use a computational intelligence algorithm for preparing a mapping map that categorizes different patterns of identification of infected areas and changes in radiation pollution. In this paper, the use of the fuzzy inference system has been proposed to determine the degree of radiation contamination in the regions. The study uses ultra-high resolution spec...
