The lowest detection limit of 0.5 mug.g(-1) was achieved by RPAA, the detection limit of the non destructive and interference-free PIGE method was by one order of magnitude higher, whereas two to three orders of magnitude higher detection limits compared to RPAA were obtained in INAA. A satisfactory agreement was found between the results obtained in this work and reference, mostly information values for several biological and environmental materials. However, higher values of two orders of magnitude were determined by RPAA and PIGE in NIST RM-8414 Bovine Muscle compared to the fluorine information value.
