Detection of irradiated fish using EPR of fish bone; signal intensity and stability

Electron paramagnetic resonance determination of prior irradiation was performed upon two sets of samples of fat-free fish bone, obtained from fish irradiated at controlled doses unknown to the spectroscopist, 4 and 8 months before the spectra were taken. A definite distinction between irradiated an...

Description
Summary:Electron paramagnetic resonance determination of prior irradiation was performed upon two sets of samples of fat-free fish bone, obtained from fish irradiated at controlled doses unknown to the spectroscopist, 4 and 8 months before the spectra were taken. A definite distinction between irradiated and non-irradiated samples was detected. Despite an apparent correlation between dosage and signal intensity, the results could not give a quantitative estimate of the same. The lowest level of irradiation detectable is far above that which might prove sufficient in combination treatments.
