“…For LSC measurements 55 Fe is prepared by Fe(OH) 3 precipitation (with ammonia) from its corresponding fraction, redissolving the dried precipitate in 200-300 µl HF (40%) and 5-10 ml H 2 O. The fluoride ions form a colourless complex with Fe(III) resulting in a strong colour quench suppression [25,26].…”

A pilot study to quantify 55Fe in steel from a reactor vessel of a nuclear power plant by accelerator mass spectrometry (AMS) without any chemical sample preparation was validated by liquid scintillation counting (LSC) and AMS after radiochemical separation. AMS reaches an uncertainty < 10% at the 1 kBq gFe−1 level within less than 10 min measuring time. The background was < 3 Bq gFe−1, presently limited by the short measurement time. The new instrumental AMS method for analysing 55Fe from neutron capture production is reasonable and fast compared to other analytical methods.
