dose response relationship



Measurement of the relationship between the quantity of a substance or exposure to radiation (the dose) and its overall effect (the response) on an organism. Response may shift dramatically with increase in dose, as in the case of carbon monoxide which produces only drowsiness in small quantities but kills in large doses. Also called dose response assessment. See also toxicity.
