Aim of this work was the development of a sensitive procedure to detect low-dose irradiation in the scale of 0.5 Gy to 20 Gy in goose fat by detection of 2-dodecylcyclobutanone (2-DCB). The general procedure to detect 2-alkylcyclobutanone (2-ACB) according to EN 1785 was optimized by using acetonitrile for extraction of 2-DCB from the lipid fraction before clean-up with silica gel. Gas chromatographic separation was realized by a 15 m TG-5 HT column, and detection was done by using a triple-quad tandem-mass spectrometer in SRM-mode. At the irradiation level of 2 Gy, the optimized procedure showed high repeatability (3.9%), a good intermediate precision (20.9%) and an acceptable recovery rate of 57.8%, with 0.25 ng 2-DCB per gram of fat. With this procedure, a reliable proof of 2-DCB was possible for the irradiation intensities 20, 5 and 2 Gy for three mass transitions; for 0.5 Gy, a proof was possible for one mass transition.
