(5)           Subject to Rule .1604(b) of this Section, the licensee or registrant does not authorize a planned special exposure that would cause an individual to receive a dose such that the individual's dose from all planned special exposures and all doses in excess of the limits would exceed:

(a)           the numerical values of any of the dose limits in Rule.1604(a) of this Section in any year; and

(b)           five times the annual dose limits in Rule .1604(a) of this Section during the individual's lifetime.
