Full energy peak (FEP) A full energy peak (FEP) appears when the incident gamma ray is absorbed completely by the detector. Basically at all cases then gamma ray losses all the energy contribute to the FEP no Se hela listan på www2.lbl.gov The gamma spectrum is characteristic of the gamma-emitting nuclides contained in the source, just as in optical spectroscopy, the optical spectrum is characteristic of the material contained in a sample. Gamma-ray characteristics Gamma rays are the highest-energy form of electromagnetic radiation, being physically the same all other Mixed gamma sources are designed for use as reference sources. They offer a convenient means of using more than one isotope at a time. Typical applications include: teaching, training, research, radiation protection, and up-and-coming technologies.

True coincidence summing correction factors for Ba-133, Eu-152 and Sb-125 were determined experimentally for a small volume source and compared with correction factors obtained with three softwares (EFFTRAN-X, GESPECOR and VGSL). The radionuclides investigated have a relatively challenging decay scheme and their spectra are known to suffer from losses due to summation (gamma-gamma, gamma-X and P. De Felice ±Uncertainty in gamma spectrometry N.12/78 Total count rate Methods for determination: o Sum of counts in the whole pulse-height spectrum, with linear extrapolation to zero count rate o Integral counting above an energy threshold Total count rate: well-defined quantity (for a given threshold) corresponding to the energy of incident gamma-rays of a single energy.

The experiments as described will work with any NaI(Tl) detector-MCA combination, but the Experi-ment #9 detector efficiencies will be different for other detector sizes. A small set of gamma sources is necessary to complete most of these experiments.
