Few exposures generate more anxiety to the public than exposure to any type of radiation. Images and stories of affected individuals that agonize due to extreme exposure to ionizing radiation (usually during nuclear facility accidents) have captured the imagination of people since the atomic bomb explosions in Hiroshima and Nagasaki during World War II, and have created deep seated fears [1,2]....

The current radiation rules, based on epidemiological data obtained from the cancer risk of A-bomb survivors, were formulated in the context of extremely high dose rates. The International Commission for Radiological Protection (ICRP) proposed a dose and dose-rate effectiveness factor (DDREF) of 2 based on two high and low dose-rate categories of A-bomb data for an extremely high dose-rate rang...

Introduction Guilan is one of the provinces in North of Iran, with population of 2,480,874 and a total area of ​​14,042 square kilometers. This study assesses the outdoor natural gamma dose rates in the air of 49 cities in Guilan and calculates corresponding average annual effective dose. Materials and Methods A total of 260 different sample points measurements were carried out. The results inc...

Background: The annual effective dose equivalent (AEDE) due to ionizing radiation in a coaster area in Nigerian has been determined using Geiger-Muller counter. Materials and Methods: isolevels in the study area were represented by using the kriging interpolation technique on ArcGIS 10.1 software. Duncan multiple range test was performed using Statistical Package for Social Sciences (SPSS). Res...

Background: Natural background radiation of a particular region is one of the distinctive factors defining the status of environment. Eloor Island is an industrial area in Ernakulum District of the state of Kerala, India. The indoor and outdoor gamma level measurements have been carried out for the region for evaluating the annual effective dose to the population residing in this area. Mate...

The advances in digital imaging and the improvement in interventional tools and devices like catheters and stents have expanded the use of interventional procedures. During the period 1998-2008, the total number of interventional procedures increased by 78% [1]. Interventional radiology [IR] and cardiology [IC] procedures deliver high radiation doses both to patients and medical personnel, whic...

Background: Since 1996 the assessment of environmental gamma radiation dose in residential areas of Iranian towns and cities has been accomplished for 10 counties. As a practical method and based on the results of a pilot study, in order to attribute the final results to the whole residential area of a town five stations were selected for every town. The location of individual station wa...

The present paper describes a detailed study on the distribution of radionuclides along Chavara - Neendakara placer deposit, a high background radiation area (HBRA) along the Southwest coast of India (Kerala). Judged from our studies using HPGe gamma spectrometric detector, it becomes evident that Uranium ((238)U), Thorium ((232)Th) and Potassium ((40)K) are the major sources for radioactivity ...

Nuclear power plant safety performance indicators are developed "by nuclear operating organisations to monitor their own performance and progress, to set their own challenging goals for improvement, and to gain additional perspective on performance relative to that of other plants". In addition, performance indicators are widely used by regulatory authorities although the use is not harmonised....
