Radioactivity: What is nuclear radiation?

 

 

 

In this movie, several important characteristics of three types of nuclear radiation (alpha, beta and gamma radiation) are shown, like the penetration through (shielding) materials. Some applications are described as well. 

During the experiments in this movie, we work with low active, encapsulated, radioactive sources. Because of this, there is no increased irradiation risk and no additional safety measures are necessary.
