DETECTION OF IRRADIATED CHICKEN AND DOSIMETRIC PROPERTIES OF DRUMSTICKS BONES

Electron spin resonance (ESR) spectroscopy was used to detect irradiat ed chicken and to investigate the dosimetric properties of chicken dru mstick bones. A model of two different radicals was used to determine the ESR parameters of the radiation-induced radicals. Dose-response cu rves for drumstick bone irradiated with its surrounding meat and irrad iated bone powder were constructed in the dose ranges of 0-10 and 0-22 kGy, respectively. It was found that both of these curves increase li nearly with dose over the likely commercial range (0-10 kGy), and that the dose-response curve of irradiated bone powder shows a biphasic ch aracter in the applied dose range (0-22 kGy). Long-term (5 months) sta bility studies on a sample stored at 4 degrees C showed a decline in t he ESR signal intensity by about 10% over the first 10-12 days of stor age.
