A strippable film of polyvinyl alcohol (PVA) for decontamination of radioactive dusts on stainless steel (SS) device surface was developed by investigating the film-stripping ability from the SS surface and the contamination-removal efficiency of the films of various preparation parameters. They include PVA concentration of the film-making solution
and amounts of EDTA-Na-Ca as complexing agent
CMC-2Na as thickening agent
PEG-200 as plasticizer
nmCaCO3 as surfactant
and 1.85 mol/L HCl. The PVA film
which can be dried in 8 h
is capable of removing over 80% of surface contamination of 90Sr at 0.02-0.20 Bq/cm2.
