  "Description": "Process in-situ Gamma-Ray Spectrometry for Luminescence\nDating. This package allows to import, inspect and correct the\nenergy shifts of gamma-ray spectra. It provides methods for\nestimating the gamma dose rate by the use of a calibration\ncurve as described in Mercier and Falguères (2007). The package\nonly supports Canberra CNF and TKA and Kromek SPE files.",
