WebThe earliest outward reaction of the skin is transitory reddening (erythema) of the exposed area, which may appear within hours after a dose of 6 Gy or more. This reaction typically lasts only a few hours and is followed two to four weeks later by one or more waves of deeper and more prolonged reddening in the same area. Webionization, in chemistry and physics, any process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules ( ions) through … WebThe rate of aspirin absorption remained linear with its concentration (0.5 to 10 mM). Intestinal aspirin absorption increased as the concentration of hydrogen ion, sodium taurocholate, and ascorbic acid in the perfusate increased. Aspirin absorption did not change after ethanol addition. china priority chemical list
