Based on the model in MIRD Dose Estimate Report No. 2 (data gathered in human subjects), J Nucl Med 14:755-756, 1973. Dynamic bladder model with 4.8-hour voiding interval.

Estimate calculated using phantom of Cristy & Eckerman (Report ORNL/TM-8381/V1 & V7). Bone and marrow model of Eckerman (Aspects of dosimetry of radionuclides within the skeleton with particular emphasis on the active marrow, In Fourth International Radiopharmaceutical Dosimetry Symposium; A.T. Schlafke-Stelson and E. E. Watson eds. CONF-851113, Oak Ridge Associated Universities, Oak Ridge, TN 37831, 1986. pp 514-534.) used.
