You can't.
::iwidgets::menubar does a [subst] in an [uplevel] on the value that is
supplied for the -menu option.

the way to go would be build the -menu argument
with foreach:

foreach rng 1 {
        append menuarg "radiobutton $f.range -label \"$rng\" -command {puts hello} ;"
}
menubutton $f.range -text "VALUE" -menu $menuarg

or thereabouts.

++++++++++++++++++++++++++
i get this as error output:

Error in startup script: can't read "rng": no such variable
     while executing
"subst {
   menubutton $f.range -text "VALUE" -menu {
     foreach rng 1 {
       radiobutton $f.range -label "$rng" -command {puts hello}
     }
   }
}"
