Atmospheric Radiation Environment Analyses Based-on CCD Camera at Various Mountain Altitudes and Underground sites

International audienceThe purpose of this paper is to discriminate between secondary atmospheric particles and identify muons by measuring the natural radiative environment in atmospheric and underground locations. A CCD camera has been used as a cosmic ray sensor.The Low Noise Underground Laboratory of Rustrel (LSBB, France) gives the access to a unique low-noise scientific environment with a depth enough great to ensure the screening from the neutron and proton radiative components. Analyses of the charge levels inpixels of the CCD camera induced by radiation events and cartographies of the charge events versus the hit pixel are proposed
