Subject:
1-131 End Breast Feeding (SMTP Id#: 1252)-
.See the November 1994 issue of the Journal of Nuclear Medicine (1994; 35:1797-1801)--for an interesting article on 1-131-in breast milk after Rx of thyroid carcinoma.- Also, this is the first article I have seen that addresses the issue of the radiation dose to the breasts.

Section 35.75 is revised to read as follows:
1 35.75 Release of individuals containing radiopharmaceuticals or permanent implants.
(a) The licensee may authorize release from licensee control any individual administered radiopharmaceuticals or permanent implants containing radioactive material if the total effective dose equivalent to any other individual (including a breast-feeding infant) from exposure to the released individual is not likely to exceed 5 millisieverts (0.5 rem).
b\\
V DRAFT: June 1, 1995 48
(b) The licensee shall provide the released individual with instructions, including written instructions, on how to maintain doses to other individuals as low as reasonably achievable if the total effective dose equivalent to any other individual is likely to exceed 1 millisievert (0.1 rem).
(c) The licensee shall maintain, for 3 years, a record of the basis for
-authorizing the release if the administered activity is in excess of the activity considered not likely to result in a total effective dose equivalent exceeding 5 millisieverts (0.5 rem) calculated based on standard conservative I
assumptions.
For the purposes of this requirement, standard conservative assumptions are:
the individual retains the initial administered activity, a i
point-source geometry, the physical half-life of the radionuclide, an occupancy factor of 0.25 at one meter, and no attenuation of radiation in-p tissue.
U (d) The licensee shall maintain for 3 years a record of the basis for authorizing the release of a breast feeding woman if immediate release with the administered activity would be likely to result in a total effective dose equivalent to the breast feeding child exceeding 5 millisieverts (0.5 rem),
assuming no interruption of breast feeding.
