Why? Radiation
is like light - shine a flashlight at something

So,... radiation is not contagious :-)
Well not if you talk about irradiated people (ie one irradiated person
can't irradiate another except in specific ways). :-)
However, one radiation source can make another object radioactive (under
the right conditions). Had loads of "fun" doing this with a "neutron
cannon". You can make all sorts of stuff "radioactive" that way!
Other techniques are used (but essentially the same) for creating
radio-pharmaceuticals (ie take a material and bombard it with the
appropriate type of radiation...neutrons, alpha, gamma...and you'll end
up with a radioactive version of it...or something related).
