Description	Proceedings of the Joint IGORR and IAEA technical meeting, October 13-18, 2013, Daejeon, Korea. The LVR-15 research reactor, situated at the site of the Research Centre Řež near Prague, is equipped with ten horizontal channels. In 2012, into one of them a special filter was mounted and a radiation shielding box was established around the channel in order to take preparations for a future neutron transmission radiography and tomography facility. Basic beam parameters comprise neutron fluence rate and spectrum, and spatial thermal neutron distribution (beam divergence). These parameters were measured with activation detectors and a silicon detector with a 6Li converter. In addition, the gamma dose rate at the channel outlet was measured using TLD dosimeters. The measured thermal neutron fluence rate was determined at the value of about 2x108 cm-2.s-1 and beam homogeneity was proclaimed acceptable at a diameter of 100 mm for the future neutron radiography facility. The results were discussed in relation to neutron radiography requirements, where the ideal case is a purely thermal homogenous parallel neutron beam.
