“For decades, ionizing radiation has been beneficial to human beings in areas ranging from medical diagnosis and therapy to scientific research to generating electrical power. However, when used in large quantities or in unsafe ways, ionizing radiation can harm living organisms. Care must be taken to properly use equipment and to minimize the potential for unnecessary radiation exposure to individuals or environmental contamination in medical, research, or power generation activities. The health physicist is prominent among scientists charged with controlling the beneficial use of ionizing radiation while protecting workers and the public from potential hazards.”
Something that is normal, that is due neither to anything pathologic nor significant in terms of causing illness. For example, physiologic jaundice is jaundice that is within normal limits.
- Physiologic amenorrhea
The cessation of menstruation for completely normal reasons. The lack of menstruation during pregnancy and lactation are forms of physiologic amenorrhea.
- Physiologic jaundice of the newborn
Yellowish staining of the skin and whites of the newborn’s eyes (sclerae) by pigment of bile (bilirubin). In newborn babies a degree of jaundice is normal. It is due to the breakdown of red blood cells (which release bilirubin into the blood) and to the immaturity of the newborn’s liver (which cannot effectively metabolize the […]
- Physiologic stress test
Although there can be a diversity of physiologic stress tests, this refers here to a physiologic cardiac stress test in which certain medications are administered that stimulate the heart to mimic the physiologic effects of exercise. One of these medications is dobutamine, which is similar to adrenaline. Dobutamine is carefully administered to gradually increase the […]
The study of how living organisms function, including such processes as nutrition, movement, and reproduction.
