Estimating Risk of Circulatory Disease from Exposure to Low-Level Ionizing Radiation

Estimating Risk of Circulatory Disease from Exposure to Low-Level Ionizing Radiation

Health effects of exposure to low-level ionizing radiation.

Reading is a hobby to open the knowledge windows. Besides, it can provide the inspiration and spirit to face this life. By this way, concomitant with the technology development, many companies serve the e-book or book in soft file. The system of this book of course will be much easier. No worry to forget bringing the health effects of exposure to low level ionizing radiation book. You can open ...

Circulatory Disease Mortality in a Canadian Occupational Cohort with Low Dose Exposure to Ionizing Radiation

Exposure to high doses of ionizing radiation, such as those received during radiotherapy, leads to increased risk of circulatory diseases.. Emerging evidence of excess risks of circulatory diseases after exposure to doses well below those considered previously as safe warrants epidemiological studies of populations exposed to low levels of ionizing radiation. The purpose of our study was to eva...

Risk of low-level ionizing radiation from medical imaging procedures.

Medical imaging procedures with x-ray, computed tomography (CT) and nuclear isotopes use ionizing radiation.1–4 On the other hand, ultrasound and magnetic resonance imaging (MRI) do not. When biological tissues are exposed to radiation, the effects are related to the type of radiation and the amount absorbed. Units of absorbed dose are grays (Gy) (joules/kilogram). One rad (radiation absorbed d...

Evaluation of Radiation Exposure Pattern and Radiation Absorbed Dose Resulting from Occupational Exposure of Anesthesiologists to Ionizing Radiation

Introduction: Little information is available concerning the radiation exposure of anesthesiologists, and no such data have previously been collected in Iran. This prospective study was performed to determine the amount of radiation exposure of anesthesiologists for the purpose of assessing whether or not dangerous levels of radiation exposures were being reached, and to identify factors that c...
