Speaker – Nolan Hertel, Georgia Institute of Technology

The presentation reviews work performed for the CDC Radiation Studies Branch by the University of Florida and Georgia Tech to obtain the count rates from various instruments which would indicate a level of internal contamination of concern. Computer simulations were employed to determine the internal distribution of the isotopes considered in the body and then compute the count rates that would be observed using different sized phantoms to represent the human body. Procedure sheets on the use of the instruments as well as the count rate thresholds of concern for up to 30 days after the intake will be presented. In addition, software developed at the University of Florida that can be used in the field to assist in performing the initial triage will be covered.
