Dear Katsuya,
   I think we have to go out of the confusion a bit...
   You have a primary beam of 440 GeV protons hitting a target containing
several radioactive materials. Therefore you have to use the card BEAM 
*only* to describe the impinging protons  (maybe you were confused because
FLUKA has the possibility to model radioactive beams, but this is a
*completely* different case!). Then you build your geometry and you assign
to the modeled regions all the materials/compounds you have. 
Please find help in the online material of the FLUKA courses... (

Here what you need first:

After that, in order to be able to evaluate the residual dose rates, give a
look at the activation lecture:

Hope it helps,
