The radioisotopes used to test reinforced concrete were Co/sup 60/ (for material of a thickness of 25 cm and more), Cs/sup 137/, Ir/sup 192/ (for thin material), and Tm/sup 170/. Two Co/sup 60/ preparations were used to study the position of three l0 mm thick steel wires embedded in l7-cm thick reinforced concrete. This was done either by measuring the intensity of rays passing through the concrete beam, using a counter and a preparation with an activity of 2.3 mc; or, when using a preparation with an activity of 50 mc, by representing the different radiation intensities on an Agfa-Texo-S film (epiposure: 6-10 hrs) placed in a box and put on the beam. The position of the steel wires could be accurately determined in both cases. The tests will be continued with reinforced concrete floors. (OTS)
