Time resolution investigations for general purpose plastic scintillation detectors in different thicknesses

Time spectra of Sr-90, Cs-137 and Bi-207 radioactive sources were obtained by using a BC 400 type plastic scintillation detectors in different thicknesses. Time resolution values through the time spectra were obtained by means of leading edge and constant fraction timing methods. The obtained time resolution values from leading edge method were compared with those of constant fraction timing method.
