Air dried-microbial cells were irradiated with high-dose X-ray for 0 to 66,500 Gy and high-energy Fe ions for 0 to 2,000 Gy to examine their survivability based on the biological \"energy currency\", i.e., adenosine 5'-triphosphate(ATP), and the Most probably number (MPN). The well known radiation-resistant bacteria such as genus Deinococcus and Rubrobacter radiotolerans, highly stress-resistant spore former family Bacillaceae and radiation-sensitive Escherichia coli strains were used for this experiment. Irradiation of synchrotron X-ray (0.2 nm) at a high dose rate of 4.4 Gy/s (500 R/s) was done at KEK Photon Factory. All species showed exponential decrease in MPN against total dose. However, celluar ATP showed little decrease at low dose and linear (or exponential) decrease at high dose. Genus Deinococcus and Rubrobacter radiotolerans showing survival at 67 kGy, was more than 60 times resistant compared with normal E. coli. Irradiation of 500 MeV Fe ion at a dose rate of 0.172 Gy/s (2.5 x 10(exp 8) particles/s) was done at NIRS HIMAC. Generally similar results to X-ray irradiation were observed, but some genus Deinococcus and Rubrobacter radiotolerans showed no decrease at total dose 2000 Gy. And celluar ATP showed no decrease against to the dose. More biomacromolecule should be used in future study.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
