DAC, DACF, %DAC DAC, DACF, %DAC

and DAC-hoursand DAC-hoursDerived Air Concentration (DAC) – concentration of a given radionuclide in air, which if breathed by the reference man for

a working year of 2000 hours under conditions of light work, results in an intake of one ALI, annual limit on intake.

DAC Fraction (DACF) – the fraction of the DAC value that ispresent. It is calculated by dividing air activity by the limit.

%DAC – the percentage of the DAC value that is present.

DAC-hour – indicates the amount of exposure. It is calculated by multiplying the DACF or the %DAC by the time in the area.
