Dose, английский
- The quantity of energy imparted to unit mass of matter (such as tissue) by ionising radiation . unit gray (gy). {1gy = 1 joule per kilogram}. in the older (non si) units it can be shown that 1gy = 100 rads.
- 1. a measured quantity of a drug or radiation which is to be given to someone at one time it is dangerous to exceed the prescribed dose. 2. a short period of experiencing a minor illness (informal ) a dose of flu 3. an infection with a sexually transmitted disease (informal) verb to provide someone with medication (informal ) she has been dosing herself with laxatives.

Dose (for chemicals that are not radioactive), английский
The amount of a substance to which a person is exposed over some time period. dose is a measurement of exposure. dose is often expressed as milligram (amount) per kilogram (a measure of body weight) per day (a measure of time) when people eat or drink contaminated water, food, or soil. in general, the greater the dose, the greater the likelihood of an effect. an "exposure dose" is how much of a substance is encountered in the environment. an "absorbed dose" is the amount of a substance that actually got into the body through the eyes, skin, stomach, intestines, or lungs.
Dose (for radioactive chemicals), английский
The radiation dose is the amount of energy from radiation that is actually absorbed by the body. this is not the same as measurements of the amount of radiation in the environment.

Dose equivalent, английский
The product of the absorbed dose in tissue, quality factor, and all other necessary modifying factors at the location of interest. the units of dose equivalent are the rem and sievert (sv).

Dose limit, английский
Dose limits, английский
With respect to radiation protection , dose limits are recommended by international bodies such as the icrp , and then set as legal limits within individual counties legislation. for example, in the uk dose limits to employees of radiation employers, memb
Dose meter, английский
Dose or radiation dose, английский
A generic term that means absorbed dose, dose equivalent, etc. and represents the total amount of radiation received during the applicable period of exposure.
Dose protraction, английский
Dose range, английский
Диапазон доз. диапазон доз от минимальной действующей до максимальной терапевтической. dose-ranging study: исследование по подбору доз. исследование (обычно i или ii фазы), в котором используются различные дозы исследуемого препарата для подбора оптимальной дозы.
Dose rate, английский
Radiation dose delivered per a specified unit of time and measured, for instance, in sieverts per minute. see also absorbed dose.
Dose rate meter, английский
Dose response curve, английский
Кривая зависимости эффекта от дозы. если построить график в координатах доза (по оси x) и соответствующий ответ на нее (по оси y), получится кривая зависимости эффекта от дозы. чем выше назначенная доза, тем сильнее ответ организма; обычно на практике кривая имеет сигмовидную форму. при низких дозах препарата эффект минимален, повышение дозы сопровождается соответствующим усилением эффекта, а в конце кривая выходит на плато, так как дальнейшее повышение дозы не приводит к изменениям, поскольку максимальный эффект уже достигнут.

Dose-response relationship, английский
The relationship between the amount of exposure [dose] to a substance and the resulting changes in body function or health (response).
