l(a) The licensee may authorize the release from its control of- any
-individual who has been administered radiopharmaceuticals 'or permanent -
implants containing radioactive material- if the total' effective dose-
. equivalent to any other-individual, including a breast-feeding child,: from exposure to-the released individual'is not likely to exceed 5 millisieverts (0.5 rem).'
(b) The licensee shall; provide the released individual with r

equivalent to any other individual is' likely ~to exceed 1 millisievert (0,1 rem).
(c) The licensee shall maintain a record of'the ' basis for authorizing.
the release-of an individual for 3 years if the calculation of external dose i
.to other. individuals, on-which the release is based, uses assumptions other than the following --
(1) The l initial administered activity;,

(d) The licensee shall maintain a record of the basis for authorizing the release of a breast-feeding woman for 3 years if release with the adtrinistered activity would be lixely to result in a total effective dose equivalent exceeding 5 millisieverts-(0.5 rem) to the breast-feeding child, assuming no interruption of breast-feeding.

(a) If the total effective dose equivalent to any other individual from exposure to the released individual is not likely to exceed 5 millisieverts (0.5 rem),' the licensee may authorize the release from its control of any individual who has been administered radioactive drugs or permanent implants containing radioactive material.
(b) If the total effective dose equivalent to any other individual, including minors, is likely to exceed 1 millisievert (0.1 rem), the licensee shall provide the released individual with written instructions on the associated radiation risks and consequences of exposure and actions recommended to maintain doses to other individuals as low as reasonably achievable (ALARA).
In the case of a breast-feeding woman, the instructions shall include guidance regarding the interruption of broast-feeding.
(c) The licensee shall maintain a record of the basis for authorizing the release of an individual for 3 years if:
(1) The TEDE to the maximally exposed individual is calculated using a half life less than the physical half-life of the radionuclide or an occupancy factor of greater than 0.25 at cne meter; or j (2) The TEDE to a breast fed child is likely to exceed 500 mrem assuming no interruption of breast-feeding.
