Treatment Summary: | A total of 17 seven-week-old C57BL/6 female mice were randomly grouped before total body being exposed to gamma irradiation using a high activity gamma source (1250 keV 60Co). The linear energy transfer (LET) associated with these fields is in the range of 0.2-2 keV/?m. For the total body gamma radiation, the animals were isolated to the corner of their polymer cages, placed at a minimum of 100 cm from the collimated 6000 Ci 60Co source, and then irradiated to the proposed dosage. The resulting absorbed dose rate at approximately 600 mg/cm2 depth was 0.83Gy/min relative to tissue. Groups of mice were exposed to radiation doses of 0Gy (control, n=8), 3.0Gy (n=5) and 7.8Gy (n=4). After 4 days post exposure, mice were sacrificed with 70/30 CO2/O2 . |
