The natural radioactivity is very important factor of the environment and building of course. Our world is radioactive and has been since it was created. Over 60 radionuclides can be found in nature. Natural radioactivity is common in the rocks and soil, in air, water and oceans, and in our building materials and objects. There is no where on Earth that you can not find the natural radioactivity. As mentioned before, building materials and the different kinds of raw and waste materials have some natural radioactivity in them. The natural radioactivity of these must be evaluated before their application. The rational processing by liquidation or by purposive utilisation of waste is a question of the interest for all over world. The problem of real utilisation of waste in building is a matter of interest since long time, from side of the producers and also from side of building praxis. In the paper will be discussed the question of concrete utilisation of waste materials for building purpose in Slovak building conditions. The Gamaspectrometric method accomplished with apparatus JAK 202 was used to the determination of natural radioactivity of all samples of the building materials. The distribution of radionuclides in waste materials is non-homogenous, so the accuracy and precision of this determination might be problematic some times. The contents of natural radioactivity of products are influenced by the several factors for instance: structure, chemical composition of raw and waste materials, technological procedures of their production There are the present results of the evaluation of different samples of ash, stones, slag's and other materials published in the papers. The special approaches of the choice of composition building products are required from radioactivity point of view.
