The activity values were computed based on 5 millisieverts (0.5 rem) total effective equivalent dose (H). If the release is based on the dose rate at 1 meter in Column 2, the licensee must maintain a record as required by 10 CFR 35.75 (c) because the measurement includes shielding by tissue. See Regulatory Position 3.1, "Records of Release," for information of records. The activity values were computed based on 1 millisievert (0.1 rem) total effective equivalent dose (H). The duration of interruption of breast-feeding is selected to reduce the maximum dose to a newborn infant to less than 1 millisievert (0.1 rem), although the regulatory limit is 5 millisieverts (0.5 rem). The actual doses that would be received by most infants would be far below 1 millisievert (0.1 rem). Of course, the physician may use discretion in the recommendation, increasing or decreasing the duration of interruption. G46
