BACKGROUND Protection of nuclear medicine unit employees from hazards of the ionizing radiation is a crucial issue of radiation protection services. We aimed to assess the severity of the occupational radiation exposure of technicians performing scintigraphic examinations at the Nuclear Medicine Department, Central Teaching Hospital of Medical University in Lódz, where thousands of different di...
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, ...
although there are substantial experimental, epidemiological and clinical evidences that high doses of ionizing radiation cause cancer and other detrimental biological effects, the health effects of human exposure to chronic low dose radiation exposures are still poorly known. people in some areas around the world live in dwellings with radiation and radon levels as much as more than 200 times ...
Exposure to ionising radiation leads to a radiation dose. The main health effect of low levels of radiation dose is an increase in the chance of developing cancer. The radiation risk factor quantifies the level of risk caused by a given amount of radiation dose, i.e. there will be an X% risk of getting cancer per unit of dose received. This document provides an introduction to the risks from ex...
BACKGROUND The eye is well known to be sensitive to clearly high doses (>2 Gy) of ionizing radiation. In recent years, however, cataracts have been observed in populations exposed to lower doses. Interventional cardiologists are repeatedly and acutely exposed to scattered ionizing radiation (X-rays) during the diagnostic and therapeutic procedures they perform. These "low" exposures may cause d...
Radiation exposure with use of intraoperative fluoroscopy is a potential orthopedic occupational risk factor. The purpose of this study was to perform a prospective comparison of hand versus eye radiation exposure associated with mini-C-arm utilization and to test the hypothesis that routine mini-C-arm does not yield hand or eye dosages exceeding current recommended levels. Over a 12-month peri...
Radiation risk allied to invasive cardiology is relatively high, and protecting both patients and cardiologists is necessary. The aim of this review is to discuss how to better protect patients and cardiologists against radiation exposure. We performed a global search on PubMed, Science Direct, and Scopus databases via keywords of "interventional cardiologist", "patient", "radiation", and "expo...
The TECHREC project, funded by the European Commission, will provide Technical Recommendations for Monitoring Individuals for Occupational Intakes of Radionuclides It is expected that the document will be published by the European Commission as a report in its Radiation Protection Series during 2016. The project is coordinated by the European Radiation Dosimetry Group (EURADOS) and is being car...
Introduction and purpose: The growing use of ionizing radiation in disease diagnosis necessitaes the appropriate use of devices and awareness regarding the principles of radiation protection. With appropriate adoption of personal protection equipment and compliance with the existing regulations in relation to protection of the buildings where sources of ionizing radiation ar...
Background and Aim: In recent decades many guidelines has been conducted by radiation protection organizations about radiation protection in dentistry. This study was designed to evaluate the observance of these guidelines in educational clinics of all dental schools in Iran.Materials and Methods: In this cross-sectional study a questionnaire based on National Radiation Protection guidelines wa...
