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
