What is the term for the annual intake of a radionuclide by Reference Man that would result in a committed effective dose equivalent of 5 rems or a committed dose equivalent of 50 rems to an organ?

What is the term for the annual intake of a radionuclide by Reference Man that would result in a committed effective dose equivalent of 5 rems or a committed dose equivalent of 50 rems to an organ?

• A. ALI
• B. DAC
• C. CEDE
• D. CDE

Answer: (A)

Annual Limit on Intake describes the amount of a radionuclide a Reference Man may take in a year such that the committed effective dose equals 5 rem or the committed dose equivalent to any organ equals 50 rem. It translates the dose limits into a permissible intake; the other terms refer to dose quantities (CEDE, CDE) or to the air concentration that would lead to that intake (DAC), not to the intake amount itself.
