The temporal profiles of scintillation exhibited a fast decay on the order of nanoseconds.<\/p>\n\n\n\n<p>The pulse-height spectra of the scintillation detectors equipped with thin-film plastic scintillators were obtained for 5.4 MeV \u03b1-rays from 241Am to evaluate the \u03b1-ray detection capabilities.
