Cancer Risk of Low Dose Ionizing Radiation

Treatment of Cancer and Inflammation With Low-Dose Ionizing Radiation

There is considerable evidence from experimental studies in animals, as well as from clinical reports, that low-dose radiation hormesis is effective for the treatment of cancer and ulcerative colitis. In this study, we present 3 case reports that support the clinical efficacy of low-dose radiation hormesis in patients with these diseases. First, a patient with prostate cancer who had undergone ...

Human EPR Dosimetry at Low Accumulated Dose of Ionizing Radiation Human EPR Dosimetry at Low Accumulated Dose of Ionizing Radiation

A new method for tooth (enamel and dentine) and bone EPR dosimetry is proposed that enhances substantially the dosimetric sensitivity. The method is based on the nonstandard spectra registration mode (the second harmonic phase quadrature detection of absorption under rapid passage conditions). This method provides an apparent enhancement of the component ratio of radiation to a nonradiative bac...

The biobehavioral and neuroimmune impact of low-dose ionizing radiation.

In the clinical setting, repeated exposures (10-30) to low-doses of ionizing radiation (≤200 cGy), as seen in radiotherapy for cancer, causes fatigue. Almost nothing is known, however, about the fatigue inducing effects of a single exposure to environmental low-dose ionizing radiation that might occur during high-altitude commercial air flight, a nuclear reactor accident or a solar particle eve...

Cancer risk models for ionizing radiation.

Risk estimation in radiation carcinogenesis depends primarily on epidemiological data and hazard rate models. The A-bomb survivors follow-up provides information on the complexity of this process. Several hazard rate models are briefly discussed and illustrated using the A-bomb experience.
