Types of Radiation:

Types of Radiation Alpha + charged particle (Helium nucleus) Beta - charged particle (electron) Gamma High-energy electromagnetic waves

Where does radiation come from?:

Where does radiation come from? Naturally radioactive elements Unstable nuclei Spontaneously decay Synthetic elements Transmutation – combining two elements to form one larger element
