In tzerk/gammaSpec: Analyse Gamma Spectra of NaI(Tl) Scintillation Radiation Detectors

#' Analyse Gamma Spectra of NaI(Tl) Scintillation Radiation Detectors
#'
#' A minimal package to import and plot SPE files recorded by
#' ORTEC NaI(Tl) Scintillation Radiation Detectors with a digiBASE 
#' Digital Multichannel Analyser as well as to derive the external wet 
#' gamma dose rate.
