Derived air concentration definition

Derived air concentration. (DAC) means the concentration of a given radionuclide in air which, if breathed by the reference man for a working year of 2,000 hours under conditions of light work, results in an intake of one ALI. For purposes of these regulations, the condition of light work is an inhalation rate of 1.2 cubic meters of air per hour for 2,000 hours in a year. DAC values are given in Part 4, Appendix 4B, Table 4B1, Column 3.
Derived air concentration. (DAC) means the concentration of a given radionuclide in air which, if breathed by the reference man for a working year of 2,000 hours under conditions of light work (inhalation rate 1.2 cubic meters of air per hour), results in an intake of one ALI. (Annual Limit on Intake defined in Rule .03 (2) (d)) DAC values are given in Table 1, Column 3 of Appendix B to 10 CFR 20.1001 - 20.2401.
Derived air concentration or “DAC” means the con- centration of a given radionuclide in air which, if breathed by the reference man for a working year of 2,000 hours under conditions of light work, results in an intake of one ALI.
