Cell suspensions of S. aureus and B. cereus and spore
suspension of C. sporogenes were irradiated in a Gamma
Cell 220 at a dose rate of 0.014 kGy/min. Maximum
dose employed for S. aureus and B. cereus was 2.5 kGy
whereas that for C. sporogenes was 14 kGy. IM mutton
kababs inoculated with test organisms were also subjected
to radiation treatment as described above. Irradiation
was carried out at 28 ± 2 C. Non-irradiated
samples were also stored at same temperature till irradiation
was over.
