(a)      Cause any employee, within a restricted area, to be exposed to airborne radioactive material in an average concentration in excess of the limits specified in table 1 of appendix B to 10 CFR  Part  20.  The   limits given in table 1 are for exposure to the concentrations  specified   for  40 hours in any workweek of 7 consecutive days. In any such period where the number of hours of exposure is less than 40, the limits specified in the table may be increased proportionately. In any such period where the number of hours of exposure is greater than 40, the limits specified in the table shall be decreased proportionately.

(b)     Cause any individual within a restricted area, who is under 18 years of age, to be exposed to airborne radioactive   material  in  an  average concentration in excess of the limits specified in table II of appendix B to 10 CFR Part 20. For purposes of this rule, concentrations may be averaged over periods not greater than 1 week.

(2)       "Exposed" as used in this rule means that the individual is present in an airborne concentration.

(3)     No allowance shall be made for  the  use   of  protective   clothing, equipment, or particle size.
