Query: A simple technique for gamma ray and cosmic ray spectroscopy using
  plastic scintillator   A new and simple technique has been developed using plastic scintillator
detectors for gamma ray and cosmic ray spectroscopy without single channel
analyzer (SCA) or multichannel analyzer (MCA). In these experiments only a
leading edge discriminator (LED) and NIM scalers have been used. Energy
calibration of gamma spectra in plastic scintillators has been done using
Co$^{60}$ and Cs$^{137}$ sources. The details experimental technique, analysis
procedure and experimental results has been presented in this article.
