Abstract

Radioactivity accompanied by ionizing radiation has always existed on the Earth, as well as in space, and so in every living tissue there are traces of radioactivity. With the discovery of the said radiation and identifying its effects on the human body, the fear of this phenomenon appeared. At high doses radiation causes serious tissue damages, while at small doses it can cause cancer and induce genetic defects. The best antidote for fear is knowledge. It is important to know the margins safety of radiation for human life. As a result, the topic of radioactive contamination of the environment has now become one of the most significant. In recent years the radon problem is a subject of a wide debate of geologists, geophysicists, ecologists, physicians, specialists in radiometry, and, of course, philosophers and sociologists, since the need for assessing the potential radon danger concerns human lives, human functions in society, and human future.
