Cosmic-ray muography has been used for the inspection of geological and industrial structures (e.g. fuel in nuclear reactors). However, the muon imaging of small structures with low atomic number and density was not yet solved appropriately. Completely new imaging method by cosmic-ray muon s, based on the detection of secondary produced radiation in object material has been demonstrated by our research group. Taking advantage of the production rate of secondaries in the target materials, detected in coincidence with muons by plastic scintil lator detectors, together with muon tracker, the first cosmic-ray muon images of bone and soft tissue were created. These pictures represent the first radiographies of structures of organic origin ever recorded by cosmic rays. The research using Monte-Carlo (MC) simulations, done by Geant4 software, includes simulations of the interactions of cosmic-ray mu ons with different detectors and different target materials in order to optimize the experimental setups and further investigate the processes leading to image creation. In this work, we will present two experimental setups in Novi Sad (MUCA) and Budapest (COMIS), used for muography of different test materials and the obtained images via those setups. MUCA - Muon Camera setup consists of 4 plastic scintillation detectors (50 cm × 50 cm × 5 cm) and muon tracker (5 CCC boards 25 cm x 25 cm) placed above the object imaged. COMIS (Cosmic Muon Induced Secondaries) experimental setup is comprised of muon tracker (5 CCC boards 50 cm x 50 cm, with 2 mm resolution) placed below the object im aged, 4 plastic scintillation detectors (50 cm × 50 cm × 5 cm) positioned around the object and 4 plastic scintillation detectors (25 cm × 25 cm × 5 cm) under the target volume. The aim of this research is to provide imaging and composition study of various obje cts, emphasizing low atomic number and density materials, using only natural omnipresent cosmic radiation.
