BS EN 1786:1997 PDF

Scope: This European Standard specifies a method for the detection of meat containing bone and fish containing bone, which have been treated with ionizing radiation, by analysing the electron spin resonance (ESR) spectrum (also called the electron paramagnetic resonance (EPR) spectrum) of the bones, see [1] to [11]. Inter-laboratory studies have been successfully carried out with beef bones, trout bones and chicken bones, see [12] to [18]. Since the radiation-induced ESR signal is attributed to hydroxyapatite (see 7.1), which is the principal component of bones, it is expected that application of the method can be extended to all meat and fish species containing bones. These expectations are consistent with laboratory experience (see annex B). The detection limit depends on the state of mineralization of the bones, which is usually lower for small species (see clause 8).
