Introduction: Medical professionals performing fluoroscopy guided interventional procedures in cardiology are exposed to a risk of radiation induced cataract, especially if the eye lens dose exceeds annual limit 20 mSv. Aim: The aim current study is measure exposure three departments, analyze relationship between patient and effectiveness lead goggles without side protection. Material methods: ...

Purpose: The aim of this study is to comparatively examine the possibility reducing exposure dose organs at risk, such as hippocampus and lens, improving distribution planned target volume with without use a head-tilting base plate in hippocampal-sparing whole-brain radiotherapy using tomotherapy. Methods: Five paired images head computed tomography tilt were analyzed. planning contoured accord...

BACKGROUND Several epidemiological investigations show a correlation between cataract development and the dose of ultraviolet radiation (UVR) received. It is experimentally well established that exposure of animal eyes to UVR induces cataract. Most cataracts develop as a gradual increase in lens opacity. Despite this, current estimations of toxicity for cataract are based on the concept that ca...

Preliminary results of the Polish epidemiology study on eye lens opacities among interventional cardiologists (ICs), based on the methodology proposed by ELDO (epidemiological studies of radio-induced cataracts in interventional cardiologists and radiologists: methodology implementation), are presented. The aim of the study is to test the hypothesis concerning the excess risk of cataract in the...

Elevated cataract risk after radiation exposure was established soon after the discovery of X-rays in 1895. Today, increased cataract incidence among medical imaging practitioners and after nuclear incidents has highlighted how little is still understood about the biological responses of the lens to low-dose ionizing radiation (IR). Here, we show for the first time that in mice, lens epithelial...

Introduction: Computed tomography is one of the most powerful tools for investigating thorax disease, because it shows progression of lung disease much clearer than chest radiography. Technical advances in CT scanners have led to some abilities for CT scanners such as coverage of larger volume, lower noise and ability for acquiring image in one respiratory phase. However, this will be accompani...

The principal objective of radiation protec­tion is to ensure that the dose received by any individual does not exceed the applicable M.P.D. values.We will discuss in this paper the presents recommendations and technical information related to the design and installation of struc­tural shielding with taking into account the concept of Maximum Permissible Dose equi­valent (MPDl as expressed and ...

results the electrophysiology laboratory staff received higher doses of ionizing radiation (17.2 ± 11.9 msv; p < 0.001). there was a significant positive correlation between the years of working experience and effective dose in the lens (p < 0.001). in general, our findings showed that the incidence of lens opacity was 79% (95% ci, 69.9-88.1) in participants with exposure (the case group) and o...
