What is the difference between nuclear radiation and
electromagnetic radiation?
Nuclear radiation is any energy or particle that is emitted from the nucleus of an atom.
EM radiation is an electromagnetic wave capable of transferring energy through space.
Some forms of nuclear radiation are EM

True or false: Substances that exhibit fluorescence are
radioactive.
True or false: Substances that exhibit fluorescence are
radioactive.
False – Fluorescence is the
emission of light when exposed to radiation. Sometimes this is due to gamma emissions but ultraviolet light can elicit the
same results in some materials.
