lethal dose
Kills if taken
A lethal dose is the amount of a substance—drug, poison, radiation—sufficient to cause death.
In pharmacology and toxicology, LD50 designates the dose lethal to fifty percent of test subjects, a standard measure of toxicity.
The term appears in medical contexts, murder investigations, and discussions of overdose: The coroner determined she had ingested a lethal dose of barbiturates.
