Ne. Whitehead, A STUDY OF CORROSION PRODUCTS USING A COCKTAIL OF RADIONUCLIDES, Journal of radioanalytical and nuclear chemistry, 185(1), 1994, pp. 45-55
A method of detecting inaccessible metallic corrosion is proposed, in
which a gamma-emitting radionuclide added in aqueous solution to the c
ontents of a pipe or vessel attaches itself selectively to corrosion p
roducts, and then may be detected from outside using a hand-held gamma
detector. This was simulated in the laboratory in preliminary studies
. Corrosion products studied were oxidised iron, FeS, goethite, magnet
ite, spinel and oxidised stainless steel. K-d values were derived for
various radionuclides. Of the radionuclides studied, Co-60, Eu-152, Pb
-214, Bi-214 and Ra-226 potentially useful, but not Na-22 or Cs-137.
