For today's episode I am joined again by Professor Gobeille to talk more things physics.  This time we're covering nuclear energy.  Is it safe?  Is it dangerous?  If a nuclear power plant were attacked with conventional weapons, would we be safe?  Also, what is radiation?  What is nuclear radiation?  These terms tend to evoke fear from many and I think it's time we clear the air about what these things are and what they are not.
