World War II ended in the summer of 1945. Since then, we have been in the “postwar time.” This new era is not only marked by a conventional date, but also by new concrete factors among which there is the entity of atmospheric radioactivity and its consequences. Among the sources of natural atmospheric radioactivity, the polluting radon gas is at the top of the list. Radioactive radon is produced by the natural decaying of the uranium chain. Cosmic rays are another important source of radioactivity in the air. The artificial causes are the use of radioactive materials in healthcare, scientific research and ra...
