If a gamma spectrometer is used for identifying samples of unknown composition, its energy scale must be calibrated first. Calibration is performed by using the peaks of a known source, such as caesium-137 or cobalt-60. Because the channel number is proportional to energy, the channel scale can then be converted to an energy scale. If the size of the detector crystal is known, one can also perform an intensity calibration, so that not only the energies but also the intensities of … WebFeb 27, 2024 · This chapter deals with gamma background radiation that is exposed to two major natural sources: normal sources that are earthly gamma rays and astronomical … litany of loreto imagesWebAs an MBA graduate honored with lifetime membership in Beta Gamma Sigma, I bring a diverse skill set and strong academic background to … imperfect knowledge examples
