Directional Geiger-Müller detector with improved response to gamma radiation

This work describes the advantages of using directional sheath on Geiger-Müller detector. It has been experimentally demonstrated that the response of the detector to gamma radiation in intermediate energy range 100 keV to 1.5 MeV can be significantly (by up 20 % for 137Cs and up 44 % for 60Co sources) improved by using lead sheath surrounding the detector and opened in the direction of the incident radiation due to the interaction of the incident radiation in the sheath.
