The Cancer Risk from Low-Level Radiation

The cancer risk from low-level radiation.

INTRODUCTION. It is commonly stated that " any radiation dose, no matter how small, can cause cancer ". The basis for that statement is the linear-no threshold theory (LNT) of radiation carcinogenesis. According to LNT, if 1 Gy (100 rads) of exposure gives a cancer risk R, the risk from 0.01 Gy (1 rad) of exposure is R/100, the risk from 0.00001 Gy (1 millirad) is R/ 100,000, and so on. Thus th...

Letter to the editor: response to EPA position on cancer risk from low level radiation.

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...

Low-Level Radiation Improvement of Health and Therapy of Cancer

INTRODUCTION Observations of mice, rats, and human clinical trials demonstrate the efficacy of low-dose radiation immunotherapy. The immune system is an essential component of effective antimutagenic control of the enormous burden of relentless metabolic DNA alterations produced by reactive oxygen species (ROS) leaked from mitochondria. Our modeling of the human antimutagenic biosystem includes...
