The electron spin resonance (ESR) technique was tested for the identification and dosimetry of irradiated chicken eggs by ESR measurements of the shell. the spectrum of powdered egg shells was interpreted as the superposition of three signals due to long‐lived CO 3 , ‐ CO 3 3‐ and CO 2 ‐ ions of the calcium carbonate matrix. Taking the amplitude of the central peak as the dose‐dependent parameter, a linear dose‐effect relationship was obtained up to 10kGy. the results obtained suggest the use of EPR for qualitative and quantitative analysis of irradiated fresh eggs.
