Median lethal dose - Wikipedia
In toxicology, the median lethal dose, LD50 (abbreviation for " lethal dose, 50%"), LC50 (lethal concentration, 50%) or LCt50 is a toxic unit that measures the lethal dose of a given substance. [1] . The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration.
