and 61]

36. COLLECTIVE DOSE. The sum of the individual doses received in a given period of time by a

specified population from exposure to a specified source of radiation. Collective dose is expressed in

units of person-rem or person-sievert. [Derived from 10 CFR 20.1003; 10 CFR 835.2]

37. COMMITTED DOSE EQUIVALENT. The dose equivalent to organs or tissues that will be

received by an individual during the 50-year period following the intake of radioactive material. It

does not include contributions from radiation sources external to the body. Committed dose

equivalent is expressed in units of rems or sieverts.

Note: The International Commission on Radiological Protection recognizes the term

"committed equivalent dose" rather than "committed dose equivalent."

[Derived from 10 CFR 20.1003, 10 CFR 835.2]

38. COMMITTED EFFECTIVE DOSE EQUIVALENT. The dose value obtained by (1) multiplying

the committed dose equivalents for the organs or tissues that are irradiated and the weighting factors

applicable to those organs or tissues and (2) summing all the resulting products. Committed effective

dose equivalent is expressed in units of rem or sievert. (See committed dose equivalent and weighting

factor.)

39. COMMITTED EQUIVALENT DOSE. The committed dose in a particular organ or tissue

accumulated in a specified period (e.g., 50 years for workers and 70 years for members of the public)

after intake of a radionuclide. [Derived from NCRP 116]

40. COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION, AND LIABILITY

ACT OF 1980 (CERCLA). A Federal law (also known as Superfund), enacted in 1980 and

reauthorized in 1986, that provides the legal authority for emergency response and cleanup of

hazardous substances released into the environment and for the cleanup of inactive waste sites.

[Derived from DOE G 430.1-1, CERCLA]

41. CONSERVATIVE (95%) METEOROLOGY. Meteorological conditions that, for a particular area,

are relatively unfavorable for the mixing of air pollutants with surrounding, less polluted, air. The term

indicates conditions under which more favorable mixing conditions occur 95% of the time, and less

favorable mixing conditions occur only 5% of the time. [See Average (50%) meteorology.] [Derived

from DOE 6430.1A]

42. CONTACT-HANDLED WASTE. Radioactive waste or waste packages whose external dose rate

is low enough to permit contact handling by humans during normal waste management activities.
