Abstract
The results of radioactivity measurements in the environment are mainly used for dosimetric purposes. However, knowing the exact concentration of different radioactive isotopes can help us to understand the world around us. The concentrations of Ra-226, Pb-210 can be used to study the effects of the last 200 years, e.g. by studying the sediments of lakes, we can trace the ef fects of anthropological activity on nature1, 2).
By studying the ratios of different artificial isotopes, we can find out the properties of nuclear accidents and explosions. By measuring the isotopes released into the atmosphere, we can determine the location and radiological properties of contaminating sources3). By studying different plants, fungi and animals, we can better understand nature’s response to the effects of radiation4).
