Radiaton measuring instruments
The use of radioactive materials are unavoidable in present times. Despite their harmful properties, there are multiple beneficial uses. The amount of energy produces by nuclear power plants would be unimaginable earlier, although the storage of used fuel is a highly debated topic even today.
Modern medicine uses radioactive materials in multiple diagnostic procedures, while research in natural science utilize them too. Radiocarbon dating used by archeology is based on the radioactive decay of certain elements. Furthermore there are several industrial applications of nuclear materials, for example sterilization or fire-alarms.
