A large percentage is fallout. But by bombardment with neutron radiation, and to a lesser degree some others, it is possible to creat radio-isotopes within the material being bombarded. the amount should vary according to the degree of bombardment and duration as well as intensity of the exposure. The half lives vary as well according to the type of isotope created and the base material being bombarded.
so, you don't want to get "hot" stay as far away as possible for as long as posible and since nice "dense" materials like lead tend to stop radiation or prevent full exposure stay behind something nice and solid too.
