  1. Gray

    The gray is the SI derived unit of absorbed dose, specific energy and of kerma. Such energies are typically associated with ionizing radiation such as X-rays or gamma particles or with other nuclear particles. It is defined as the absorption of one joule of such energy by one kilogram of matter. Unlike the pre-1971 roentgen, the gray has always been defined independently of any target material. The same beam of 1 roentgen would impart more grays to biological tissue than it does to air. The gray is sometimes used to measure beam kerma, in which case the reference target material must be defined explicitly. The gray was named after the British physicist Louis Harold Gray, a pioneer in the field of measurement of radium radiation and X-rays and their effects on living tissue, and was adopted as part of SI by the 15th CGPM in 1975. The SI unit is similar to the traditional cgs unit, the rad, which remains common in industry in the United States, while "strongly discouraged" in the style guide for U.S. National Institute of Standards and Technology authors.
