Background: Although ionizing radiation is very important in diagnostic and treatment of many diseases, the hazards of this radiation are considerable and irrefutable. One of the main stages in radiation protection is knowledge about radiation dose in radiological investigation. The aim of this study was to determine the physicians' knowledge in radiological examinations. Materials and Methods:...

Background: Lead-based radiation shields are widely used in radiology departments to protect both workers and patients from any unnecessary exposure to ionizing radiation. Recently there has been a great deal of concern expressed about the toxicity of lead. Human lead toxicity is well documented. In that light, production of environmentally-friendly lead-free radiation shields with less weight ...

Reflecting the change in funding strategies for European research projects, and the goal to jointly improve medical radiation protection through sustainable research efforts, five medical societies involved in the application of ionising radiation (European Association of Nuclear Medicine, EANM; European Federation of Organizations for Medical Physics. EFOMP; European Federation of Radiographer...

Introduction: The ionizing radiation is increasingly applied in various fields for industrial and medical purposes due to its benefits. The aim of this study was to measure the radiation levels in six radiology departments of two educational hospitals in Ahvaz, Iran. Materials and Methods: The radiation levels were measured at six locations of six radiology departments, including behind the pat...

Introduction: Exposure to ionizing radiation can be through direct hit or water radiolysis lead to oxidation in biological systems. In this study, the protective effect of Myrtus Communis aqueous extract on structural changes and oxidative stress in red blood cells and plasma proteins was examined after receipt of ionizing radiation. Materials and Methods: wis...

The challenge for planning radiation protection in space is to estimate the risk of events of low probability after low levels of irradiation. This work has revealed many gaps in our knowledge that require further study. Despite investigations of several irradiated populations, the atomic-bomb survivors remain the primary basis for estimating the risk of ionizing radiation. Compared with previo...

Decent work is a key tool to overcome insecurities caused by a lack of choice and access to opportunities which lead to disempowerment. Decent work includes rights, social protection, employment and the promotion of social dialogue, applied in an integrated manner. The legal aspect of decent work lies at the heart of the empowerment process, helping to break the cycle of inequality by providing...

At the onset of radiation exposure, free radicals are formed through ionizing reactions that are then capable of destroying normal tissues. While cells release a level of protective molecules, such as glutathione and metallothionine, they are not capable of blocking all damage, thus resulting in the death of normal tissues and therefore, we must continue to develop strategies to protect normal ...

Potential biological damage from radiation received during fluoroscopy procedures is of particular concern because of the high volume and variety of procedures performed and the increasing length of radiation exposure. This article focuses on the effects of low-level radiation, gaps in education and skills among personnel performing and assisting with fluoroscopy, the certification and privileg...
