Since 1990, breast cancer mortality has decreased yearly in developed nations. In 2012, there were an estimated 3 million survivors of breast cancer in the United States alone.1 This decrease in mortality can be partly attributed to effective treatment strategies developed through collaborations among breast surgeons and medical and radiation oncologists. Radiation therapy has evolved as a crit...

in order to find a prophylactic supplementation for individuals who are at risk of exposure to ionizing radiation, we attempted to evaluate the effect of vitamin e (vit-e), a biological free radical scavenger, on restoration of hepatic lipid peroxidation (lpo) and lipid profile (lp) changes induced by sublethal g- radiation in balb/c mice. the concentrations of cholesterol and phospholipid were...

some areas of ramsar, a city in northern iran are among the world’s wellknown inhabited areas with highest levels of natural radiation. annual exposure levels in these areas are up to 260 mgy y‐1 and the mean exposure rate is about 10 mgy y‐1 for a population of about 2000 residents. if elevated levels of natural radiation as high as a few hundred msv per year is detrimental to health and leads...

The objective of this study was to estimate the risk of a cardiovascular event or death associated with modern radiation in a population of elderly female breast cancer patients with varying baseline cardiovascular risk. The data used for this analysis are from the linked Surveillance, Epidemiology, and End-Results (SEER)-Medicare database. The retrospective cohort study included women aged 66 ...

The radiation environment in deep space, where astronauts are behind the shelter provided by the Earth’s magnetosphere, is a major health concern. Galactic cosmic rays (GCR) and solar particle events (SPE) are two basic sources of space radiation in the solar system. The health risks of exposure to high levels of space radiation can be observed either as acute and delayed effects. Zhang et al. ...

C hildren with congenital and acquired heart disease typically undergo imaging procedures that may expose them to large amounts of ionizing radiation. Radiation exposure in childhood is of particular concern because children have immature developing organ and tissue structures. These factors , as well as the potentially longer lifespan of these children , may significantly increase lifetime can...

*Correspon In this issue of Radioprotection, K. Leuraud et al. present a comprehensive update of the main results obtained on mortality in the French cohort of nuclear workers. The publication of this article offers the opportunity to make a point on the current radiation protection system and on the strengths and limitations of epidemiology regarding the health risks associated to ionizing rad...

Recently, lay and scientific reports have raised concerns regarding the radiation doses associated with CCTA. These published data remain confusing for the nonphysicist, given the complexity of measuring radiation exposure and estimating risk. Radiation imparted by CT is most easily described by the dose-length product (DLP), a summary measure of the integral of radiation dose and scan length. ...

MELODI (Multidisciplinary European Low Dose Initiative) is a European radiation protection research platform with focus on research on health risks after exposure to low-dose ionising radiation. It was founded in 2010 and currently includes 44 members from 18 countries. A major activity of MELODI is the continuous development of a long-term European Strategic Research Agenda (SRA) on low-dose r...
