  2. Roentgen equivalent man - Wikipedia

    en.wikipedia.org/wiki/Roentgen_equivalent_man

    The concept of the rem first appeared in literature in 1945 [17] and was given its first definition in 1947. [18] The definition was refined in 1950 as "that dose of any ionizing radiation which produces a relevant biological effect equal to that produced by one roentgen of high-voltage x-radiation."

    Attention deficit hyperactivity disorder management options are evidence-based practices with established treatment efficacy for ADHD.Approaches that have been evaluated in the management of ADHD symptoms include FDA-approved pharmacologic treatment and other pharmaceutical agents, psychological or behavioral approaches, combined pharmacological and behavioral approaches, cognitive training ...

    en.wikipedia.org/.../Orders_of_magnitude_(radiation)

    Recognized effects of higher acute radiation doses are described in more detail in the article on radiation poisoning.Although the International System of Units (SI) defines the sievert (Sv) as the unit of radiation dose equivalent, chronic radiation levels and standards are still often given in units of millirems (mrem), where 1 mrem equals 1/1,000 of a rem and 1 rem equals 0.01 Sv.

  5. Rad (radiation unit) - Wikipedia

    en.wikipedia.org/wiki/Rad_(radiation_unit)

    That model calculates an effective radiation dose, measured in units of rem, which is more representative of the stochastic risk than the absorbed dose in rad. In most power plant scenarios, where the radiation environment is dominated by X-or gamma rays applied uniformly to the whole body, 1 rad of absorbed dose gives 1 rem of effective dose. [5]

    the rad (radiation absorbed dose), now replaced by the gray; and; the rem (Röntgen equivalent man), now replaced by the sievert. [25] The rad and rem are essentially equivalent for almost all nuclear medicine procedures, and only alpha radiation will produce a higher Rem or Sv value, due to its much higher Relative Biological Effectiveness ...

  7. Radiation exposure - Wikipedia

    en.wikipedia.org/wiki/Radiation_exposure

    For an exposure of 1 roentgen by gamma rays with an energy of 1 MeV, the dose in air will be 0.877 rad, the dose in water will be 0.975 rad, the dose in silicon will be 0.877 rad, and the dose in averaged human tissue will be 1 rad. [10] "rad" stands for radiation absorbed dose. [4]
