The paper discusses the role of the IAEA in relation to the radiological protection of patients. Within the IAEA there are two major programmes which have an impact on the protection of the patient. Firstly, patient protection is part of the programme on radiation safety; secondly, the human health programme contains a number of activities related to quality assurance (QA), and these also contr...

Introduction: Active personal dosimeters (APDs) are well accepted as useful and reliable instruments for individual dosimetry measurements. APDs have many advantages compared with passive dosimeters for individual external radiation dose assessments. In routine monitoring, occupational exposure is carried out for verification and demonstration of compliance with the regulatory dose limits. So, ...

PURPOSE X-ray exposure should be clinically justified and each exposure should be expected to give patients benefits. Since dental radiographic examination is one of the most frequent radiological procedures, radiation hazard becomes an important public health concern. The purpose of this study was to investigate the attitude of Korean dentists about radiation safety and use of criteria for sel...

Background: Exposure to ionizing radiation results in genotoxicity and the unrepaired lesions in cellular DNA results in cell cycle arrest, reproductive death, interphase death, division delay, chromosome aberrations, mutations, etc. leading to the intensive destruction of cells and violation of their proliferative capacity there by adversely affecting the mammalian system. Since ionizing radia...

PURPOSE Radiographs is an integral part of patient management in dentistry, despite their detrimental effects. As the literature pertaining to radiation protection among Indian dental practitioners is sparse, exploring such protection is needed. MATERIALS AND METHODS All private dental practitioners in Mangalore, India were included in the study. A structured, pre-tested, self-administered qu...

Introduction: With the rapid advancement of technology in today's world, the use of ionizing radiation and radioactive materials has been expanding significantly. The use of radioactive resources and equipment in medical sciences is increasing. Failure to observe safety precautions when working with radiation can have serious risks for employees, people, the environment and eve...

Scientific Committee 75 (SC 75) of the National Council on Radiation Protection and Measurements (NCRP) was assembled for the purpose of providing guidance to NASA concerning radiation protection in low-Earth orbit. The report of SC 75 was published in December 2000 as NCRP Report No. 132. In this presentation an overview of the findings and recommendations of the committee report will be prese...

The present review provides an understanding of our current knowledge of the carcinogenic effect of low-dose radiation in man, and surveys the epidemiological studies of human populations exposed to nuclear explosions and medical radiation. Discussion centers on the contributions of quantitative epidemiology to present knowledge, the reliability of the dose-incidence data, and those relevant ep...

INTRODUCTION The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) collect reported incidents for inclusion in the Australian Radiation Incident Register (ARIR), a database of radiation incident reports that occur within Australia. While the information on previous radiation incidents is available, there is little information on the lessons that can be learned from those past ...
