A lethal dose is an indication of the lethality of a given substance or type of radiation. Because resistance varies from one individual to another, the 'lethal dose' represents a dose (usually recorded as dose per kilogram of subject body weight) at which a given percentage of subjects will die. The LD may be based on the standard person concept, a theoretical individual that has perfectly "normal" characteristics, and thus not apply to all sub-populations.
MedicineAll that is required to care for most cuts is to wash them with soap and water and keep them clean and dry. Putting alcohol, hydrogen peroxide, and iodine onto cuts can delay healing and should be avoided. Seek medical care early if you think that the cut may need stitches. Any delay can increase the rate of wound infection.
