Epidemiological studies indicate long-term risks of ionizing radiation on the heart, even at moderate doses. In this study, we investigated the inflammatory, thrombotic and fibrotic late responses of the heart after low-dose irradiation (IR) with specific emphasize on the dose rate. Hypercholesterolemic ApoE-deficient mice were sacrificed 3 and 6 months after total body irradiation (TBI) with 0...

HDPE monofilaments were obtained using different extruders and drawn by post-extruder equipments. After solidification, drawn and undrawn monofilaments (draw ratio 7:1) were irradiated with 10 MeV electron beams in air at room temperature at 25, 50, 75, 100 and 125 kGy dose ranges to induce a network structure. HDPE crosslinking was studied on the basis of gel content measurements. The fibers w...

Cultures of Salmonella subjected to repeated cycles of gamma-irradiation and subculture developed radiation resistance sooner at a low cycling dose ( approximately 1% survival) compared to a high cycling dose ( approximately 0.001% survival). Radioresistant cells in a population of radiosensitive cells of Salmonella newport or S. typhimurium could be selected by the double-irradiation plate met...
