Large exposure received over a short period of time.
a single exposure to a hazardous material for a brief length of time
Single or multiple exposure(s) to a substance for less than 24 hours.
Acute exposure is exposure to a large, single dose of radiation, or a series of doses, for a short period of time.
A single exposure to a toxic substance that results in a severe response or death. Acute exposures are characterized as lasting no longer than a day, as compared with longer, continuing chronic exposure over a period of time.
Either a single or short term exposure to a compound.
an exposure to radiation that occurred in a matter of minutes rather than in longer, continuing exposure over a period of time. See also chronic exposure, exposure, fractionated exposure.
A single exposure of relatively short duration.
Exposure of short duration, usually to relatively high concentrations or amounts of material.
Single exposure episodes which occur over a short time period.
One dose or multiple doses of a stimulus occurring within a short time period (e.g., 96 hours or less for aquatic life, less than 14 days for human health).
Exposure to a chemical for a short duration of time. The U.S. Environmental Protection Agency (EPA) defines this duration as less than or equal to 24 hours; the Agency for Toxic Substances and Disease Registry (ATSDR) defines the duration as 1-14 days.
the absorption of a relatively large amount of radiation (or intake of radioactive material) over a short period of time.
Contact with a chemical that happens once or only for a limited period of time. ATSDR defines short-term exposures as those that might last up to 14 days.
A contact between an AGENT and a TARGET occurring over a short time, generally less than a day. (Other terms, such as ¿short-term EXPOSURE¿ and ¿single DOSE,¿ are also used.)
Refers to a single, short-term exposure to a toxic substance. Acute exposures are characterised as lasting no longer than 1 day.
Contact with a substance that occurs once or for only a short time (up to 14 days)
A dose that is delivered to the body in a single event or in a short period of time. The adverse effects resulting from a single dose or exposure to a material. Ordinarily used to denote effects observed in experimental animals.
A single exposure to a substance or multiple exposures occuring within a short time, usually 24 hours or less.
A single event or occurring in a short period of time causing an immediately noticeable symptom or effect.
single exposure to a toxic substance which results in severe biological harm or death. Acute exposures are usually characterized as lasting no longer than a day.
An intense exposure over a relatively short period of time.
a short-term exposure usually occurring at high concentration.
One dose or multiple doses of short duration within a 24 hour period.
Severe biological harm/death from a single or short term exposure to a toxin.
An exposure, often intense, over a relatively short period of time.
Exposure by the oral, dermal, or inhalation route for 24 hours or less.
One dose or multiple doses of short duration spanning less than or equal to 24 hours. This definition archived 9/30/03
