Certainly. Almost every synthetic material seems to be disposed to building
static charge on its surface and becomes a candidate for attracting
radioactive material.

The most extreme case of this that I have seen is the person carrying a
plastic bag of non-rad trash through a nuclear plant. It seems that a hot
particle in a nearby contamination area jumped onto the bag and was carried
a considerable distance before the bag was put down on a metal grating.
This discharged the accumulated static charge, and the particle fell off,
leaving the particle in a location far from any possible point of origin.
It is just this phenomenon that led nuclear plants staffs to refer to hot
particles as fleas.
