Abstract
This paper introduces a windowing algorithm for radiation portal monitors based on a transformation of random variables to calculate the ratio between the radiation intensity in two energy windows. Procedures to evaluate critical limits and establish detection limits are described. Simulations and experimental data illustrate a good agreement between derived and observed ratio distributions. The algorithm was compared with commonly-used algorithms. The results illustrate proper evaluation of critical and detection limits even in the case of shadow shielding by vehicles entering a radiation portal monitor.
