A dose was a specific concentration of an administered, or exposure to a drug, medicine, or radiation. Injected drugs were usually measured in milliliters (mL); the term cc (cubic centimeter) was also used, although they are the same volume. Radiation dosages were measured in rads. The amount or rate that a dose was given was known as a dosage. A microdose was a low dose which was unlikely to produce large physiological changes. An unnaturally high dosage of a substance was called an overdose.
