| A high flux, good scintillator or effective noise reduction is necessary for a better detection of neutron or gamma rays. We applied the principal component analysis (PCA) method to treat the gamma spectra obtained from a research reactor at the Korea Atomic Energy Research Institute (KAERI) for an effective noise reduction. After the noise reduction by the PCA, the relevant information was preserved in a singular value decomposition model while discarding much of the noise. The result of the PCA makes it possible to detect explosives in a very short time (within 20 seconds). |
