Abstract: | In order to envision the radiation exposure during Neutron Activation Analysis (NAA) experiments, a software called Activity
Predictor is developed using JavaTM programming language. The Activity Predictor calculates activities, exposure rates and gamma spectra of activated samples
for NAA experiments performed at Radiation Science and Engineering Center (RSEC), Penn State Breazeale Reactor (PSBR). The
calculation procedure for predictions involves both analytical and Monte Carlo methods. The Activity Predictor software is
validated with a series of activation experiments. It has been found that Activity Predictor software calculates the activities
and exposure rates precisely. The software also predicts gamma spectrum for each measurement. The predicted spectra agreed
partially with measured spectra. The error in net photo peak areas varied from 4.8 to 51.29%, which is considered to be due
to simplistic modeling, statistical fluctuations and unknown contaminants in the samples. |
