A review of low-level ionizing radiation and risk models of leukemia

The relationship between exposure to low doses of ionizing radiation (<100 mSv) and the risk of leukemia has perplexed researchers for decades. The recent accident in Fukushima, Japan has led to a renewed interest in better understanding this relationship, which has significant implications for government-outlined safety procedures for individuals working in occupations, such as the nuclear ind...

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...

study the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats

nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
