ZPE is also the total energy of every photon that fits within any given finite 
space, limited by it's wave length. In any volume you will find at least one 
photon for every wave length that is less or equal than the dimentions of that 
volume.
Now, how much energy does a single gamma ray photon cary? And now, how many 
times it's wave length fits within an hydrogen atom?
