Biological model based on ICRP 53 (data gathered in human subjects).

Cortical bone * = 201.6 hour Cancellous bone * = 160.8 hour
Small Intestine * = 0.6 hour Upper Large Intestine * = 2.0 hour
Lower Large Intestine * = 3.6 hour Urinary bladder * = 1.1 hour
Remainder of body * = 163.1 hour

Dynamic bladder model with 3.5-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.
