How the pacemaker contain the radioactive substances? It cannot 
be using lead right. If it does, it will be too heavy to be 
planted in the body.
How the pacemaker use the radiation to generate electric 
impulses? It is impossible to make it like a mini-nuclear power 
plant right. Otherwise, the boiling water will be too hot for 
our body and the generator will be too huge for the size of the 
pacemaker.
