A (total or accumulated) quantity of ionizing (or nuclear) radiation The absorbed dose in rads represents the amount of energy absorbed from the radiation per gram of specified absorbing material In soft body tissue the absorbed dose in rads is essentially equal to the exposure in roentgens The biological dose (also called the RBE dose) in rems is a measure of biological effectiveness of the absorbed radiation See Exposure, Rad, RBE, Rem, Roentgen
The amount of a chemical that enters or is absorbed by the body Dose is usually expressed in milligrams of chemical per kilogram of body weight (mg/kg)
a measure of the amount of exposure of a living organism to ionizing radiation that takes into account the greater biological harm of alpha radiation; measured in various units, most commonly measured in millirems per exposure episode or per unit of time (see "millirem")
More specifically referred to as "absorbed dose", this is a measure of the energy deposited within a given mass of a patient Absorbed dose is quantified by the unit called the "rad" More Information: EGS: The Medical Problem
The amount of a substance available for interaction with metabolic processes or biologically significant receptors after crossing the outer boundary of an organism The potential dose is the amount ingested, inhaled, or applied to the skin The applied dose is the amount of a substance presented to an absorption barrier and available for absorption (although not necessarily having yet crossed the outer boundary of the organism) The absorbed dose is the amount crossing a specific absorption barrier (e g , the exchange boundaries of skin, lung, and digestive tract) through uptake processes Internal dose is a more general term denoting the amount absorbed without respect to specific absorption barriers or exchange boundaries The amount of the chemical available for interaction by any particular organ or cell is termed the deliverable dose for that organ or cell
The amount of agent or energy that is taken into or absorbed by the body; the amount of substance, radiation, or energy absorbed in a unit volume, an organ, or an individual
The absorbed dose, given in rads (or in SI units, (Gy) grays), that represents the energy in ergs or Joules absorbed from the radiation per unit mass of tissue Furthermore, the biologically effective dose or dose equivalent, given in rem or sieverts, is a measure of the biological damage to living tissue from radiation exposure
a measured portion of medicine taken at any one time the quantity of an active agent (substance or radiation) taken in or absorbed at any one time treat with an agent; add (an agent) to; "The ray dosed the paint
emphasis You can refer to an amount of something as a dose of that thing, especially when you want to emphasize that there is a great deal of it. The West is getting a heavy dose of snow and rain today
Amount of a substance that remains at a biological target during a time interval With radiation, the amount of energy deposited in biological tissue during a specified time
The energy absorbed by tissue from ionising radiation One gray is one joule per kg, but this is adjusted for the effect of different kinds of radiation, and thus the sievert is the unit of dose equivalent used in setting exposure standards
If you dose a person or animal with medicine, you give them an amount of it. The doctor fixed the rib, dosed him heavily with drugs, and said he would probably get better I dosed myself with quinine. Dose up means the same as dose. I dosed him up with Valium. dose up to give someone medicine or a drug dose sb/yourself with sth
The amount of a drug to be taken For example, a healthcare professional can prescribe CELEBREX in either 100- or 200-mg capsules Also referred to as dosage
[ 'dOs ] (noun.) 15th century. Middle English, from Middle French, from Late Latin dosis, from Greek, literally, act of giving, from didonai to give; more at DATE.
