The power of gamma ray transmission installations may not necessarily be high. For example, the experience of flaw detection of welded joints has shown that low-power portable gamma installations can also be used. To make the reinforced concrete structure transparent, the container is mounted on it, and a photographic film is placed on the other side of the structure. The film shows the location and diameter of the reinforcement and the location of cracks in the concrete. The use of portable gamma installations provides significant economic benefits. However, currently gamma-ray transmission has a serious competitor - thermal imaging, which gives very good results "intra-vision&without the danger of being irradiated by penetrating rays. Passing through a material, gamma rays are absorbed by it, and the thicker the material and the higher its density. And how do you know how many gamma rays have passed through the material? After all, a person does not feel the penetrating rays and cannot quantify the intensity of radiation. And counters with an indicator — gamma ray recorders - come to his aid. But you also need to know exactly the thickness of the material. This is helped by preliminary etching on plates of known sizes made from the same batch as the controlled product.



This method is much more effective than any method of controlling geometric dimensions. But in construction practice, it is often necessary to measure the thickness of concrete slabs or roadways when access is possible to them only from one side. There is a device that will help in this. The principle of operation of such a device is based on measuring the energy of gamma radiation scattered in the opposite direction in the thickness of the material. The device diagram is simple. A narrow beam of gamma rays from the source is directed at a certain angle onto a slab or road surface. The reflected (scattered) rays are picked up by the counter, which is also located at a certain angle. The gamma ray source and the radiation meter are placed in lead containers, between which a lead shield is placed, protecting the meter from possible extraneous radiation. To increase the accuracy of measurements, the angle of inclination, intensity and energy of the source are selected. The measurement accuracy in this way is very high. The described principle is the basis for several variants of gamma density meters developed by the domestic industry.
