On the risk to low doses (<100 mSv) of ionizing radiation during medical imaging procedures - IOMP policy statement

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...

Exposure to low-dose ionizing radiation from medical imaging procedures.

BACKGROUND The growing use of imaging procedures in the United States has raised concerns about exposure to low-dose ionizing radiation in the general population. METHODS We identified 952,420 nonelderly adults (between 18 and 64 years of age) in five health care markets across the United States between January 1, 2005, and December 31, 2007. Utilization data were used to estimate cumulative ...

q American Association of Physicists in Medicine, 2013 Editor’s Note: We are pleased to reprint an editorial by William R. Hendee, PhD, editor of Medical Physics, on the policy statement on radiation risks recently adopted by the International Organization for Medical Physics (IOMP). In our recent editorial entitled “Through the Looking Glass Revisited: The Need for More Meaning and Less Drama ...

Activation of Radioadaptive Response via Injected Serum of Irradiated Rats with Low Doses of Ionizing Radiation

Introduction: One of the protective concepts in the interpretation of radiation damage in radiobiology is the radioadaptive response. The objective of this present report is to evaluate the induction of radioadaptive response in male rats by injection of pre-irradiated serum with low doses X-radiation intraperitoneally.   Materials and Methods: 80 male adul...
