Aircraft bomb frag patterns

Am trying to find some info to help accurize (a somewhat outdated)
Vietnam era flight sim - Janes Fighters Anthology. Can any of you
military folks remember any numbers about the blast frag distances for
various aircraft bombs - 500/750/2000/3000 lb? How about
nape/CBUs/2.75 in FFARs? What would be the safe release heights for
each or any of these before you can expect to be affected by your own
ordnance? I don't have access to an F-105 or F-4 dash 34 manual, but I
bet that would answer my questions.
Thanks,
Mike Druzolowski
