CAPINTEC, INC. CAPTUS
®
3000
module of the CAPTUS
®
3000 software is an emergency screening module which provides
an automated program to quickly measure intake and calculate absorbed organ dose in a
dynamic fashion. Results which exceed predefined trigger levels are flagged to alert public
health officials, who will determine the appropriate follow-up actions.
Basis for Conversion Calculations
The conversion from counts to µCi-intake is based on physical measurements using the
CAPTUS
®
3000 and computer modeling data developed at Georgia Institute of Technology,
School of Nuclear and Radiological Engineering and Medical Physics. Support and research
funding were provided by the Centers for Disease Control and Prevention (CDC). The
conversion is based on the following scientific methodology:
•
The CAPTUS
®
3000 physical measurement data and proprietary collimator design
were simulated using MCNP5, [Los Alamos Monte Carlo N-Particle Transport Code].
•
The CAPTUS
®
3000 system was modeled to respond to six body types using MIRD
1
[Medical Internal Radiation Dose] anthropomorphic phantoms.

The absorbed dose to the organ of interest was calculated over time based on
biokinetic models generated by DCAL* [Dose and Risk Calculation Software]. Data
was generated from 1 to 30 days following initial intake.

Both MIRD and DCAL were developed by Oak Ridge National Laboratory, Center for Biokinetic and
Dosimetric Research. DCAL dose coefficients are based on ICRP Publication 30.
