Since their discovery, radioactivity has been researched and used in many different ways. They have been used to generate electricity, to identify and cure diseases, or to look deep into things\/objects. Many scientific discoveries, advanced practical applications and positive effects have been discovered, and we use and benefit from them every day. However, we must not forget the downside of radioactivity: human nature, the constant state of war and the ever-increasing arms race have led to the production of nuclear bombs and the (violent) use of various isotopes and radiation for political purposes. In this course, we would like to present a brief overview of the phenomenon of radioactivity, the various defence options and the composition of background radiation of natural and artificial origin. We will review the extent of our exposure to radiation, where we will find out what is more dangerous for our exposure: working in a radiological workplace, flying, collecting minerals\/rocks or perhaps smoking?<\/p>\n\n\n\n
We recommend the performance for pupils in years 7-8 of primary school and for secondary school students.<\/p>","protected":false},"excerpt":{"rendered":"
