Neutrongraphy of several materials have been obtained at the IEA-Rl Nuclear Research Reactor by making use of two experimental arrangements. The first one installed in a beam-hole tube and the second in the bottom of the reactor pool. The film and converter screens used were the nuclear solid state track detector (N.S.S.T.D.) CN-85-2B coated with a lithium tetraborate and the Kodak Industrex T-5 with a dysprosium foil. We have obtained good results and this work is the first step of the plan to develop the neutrongraphy technique in our Institute.
