Nuclear fallout survival information?

Ive been searching around about fallout survival, just a time waster. I found this site and was wondering whether it is reliable? a href="http://www.ki4u.com/survive/index.htm" rel="nofollow"http://www.ki4u.com/survive/index.htm/a Is the information about radioactive decay correct? Do the household steps to protecting yourself that they show really work?
