ICRP PUBLICATION NO. 95

The International Commission on Radiological Protection (ICRP) has brought out recently a CD containing the ICRP publication no. 95. The publication is a complementary report to other earlier publications which provided age-specific bio-kinetic models and dose coefficients (dose per unit intake of radioactive substance) for members of the public (Publications 56, 67, 69, 71, and 72).

The ICRP-95 provides information on radiation doses to the infant due to intakes of radionuclides in maternal milk. Intakes by female members of the public and female workers are addressed, and dose coefficients per unit intake by the mother (Sv per Bq) are given for radioisotopes of 35 elements including sodium, magnesium, phosphorus, and potassium. The CD provides all the dose coefficients in Publication 95 in a handy electronic format, and includes a considerable amount of additional information. Thus, committed equivalent doses to the various organs and tissues of the offspring are provided. Dose coefficients are also given for inhalation for ten aerosol sizes (0.001, 0.003, 0.01, 0.03, 0.1, 0.3, 1, 3, 5, and 10 µm AMAD) as well as for ingestion. Effective doses and equivalent doses for all important tissues for a range of post-natal integration times (1, 5, 10, and 20 years) are given, together with the dose coefficients to age 70 years. All intake scenarios are considered.
