Factors Affecting Radiosensitivity Age: Humans are most sensitive before birth. Gender: Females are less radiosensitive than males. Molecular and Cellular Radiobiology Irradiation of Macromolecules: (p.450) Follows a Linear‚ Non-threshold dose/response relationship. Radiation Effects on DNA: DNA is the most radiosensitive macromolecule. 1) Cell death 2) Malignant disease 3) Genetic damage Radiolysis of Water: Indirect Effect. Most prevalent in humans. We are mostly water: 80% Water

Acute Radiation Syndrome Acute radiation syndrome which is also sometimes known as radiation sickness or radiation toxicity is an extremely serious illness that occurs when the entire body (or most of it) receives a high dose of penetrating radiation‚ a dose greater than 50 rads‚ in a very short period of time. Studies in animals and humans exposed to radiation have allowed researchers to describe acute radiation syndrome. The most replicative cells are the most sensitive to the acute effects

Pharmacodynamics Mechanisms of drug action: Drugs may act by: * A) Receptor mechanism: * Most drugs produce their action by binding to specific receptors located on the cell membrane (as adrenoceptors and cholinoceptors) or inside the cell (as steroid receptors). * This is the most important mechanism of drug action. * Drugs produce their effects by interacting with these receptors. * These drugs may be: a) Agonists: * Drugs have the affinity to bind with their

study by Yajima et al. (2015) details estimations of individual doses for returnees who were previously evacuated from the Fukushima Nuclear Disaster. Individual estimates were made for different categories of evacuees who were meant to return to three designated Iitate Village‚ Kawauchi Village‚ and Tamura City in Fukushima. The data required for the estimates was obtained from measurements of individual doses and ambient external dose rates in occupational and residential settings. The ratio of both
