Dear Colleagues: Just a short note to let you know that I recently ran across a really nice table from the US. Nuclear Regulatory Commission concerning the use of radioisotopes in breastfeeding women. This table is the first documentation that I have seen that is "realistic" in its recommendations. This regulation suggests that if the doses are of said strength, the Radiologist is required by law to make these recommendations to the mother. Now as you all know, they generally never look at this table, but instead opt for some unrealistic recommendation such as "stop breastfeeding" altogether. However, this table carries the weight of a Federal Agency. So you could copy this table, give it to your clients, the Radiologist would automatically have the accurate NRC data. So how do you get this table? Its in my WEB page under "Breastfeeding and Radioisotopes". The Regulatory Guide 8.39 Guide (21 pages) is the complete guidelines (they're really hard to read), so I just abstracted Table 3. which is the exact recommendations for breastfeeding mothers.
