WebThe lethal dose of radiation (LD) indicates the lethal amount of radiation. The median lethal dose, LD XY, is usually used in radiation protection.For example, the dose of radiation expected to cause death to 50 % of the irradiated persons within 30 days is LD 50/30.LD 1 is the dose expected to cause death to 1% of the irradiated persons. Consequently, LD 99 … WebChernobyl’s Hot Mess, “the Elephant’s Foot,” Is Still Lethal.
