Fоr а given biоlоgicаl system, the Do in the presence of O2 wаs determined to be 2 Gy for specific energy A and 1 Gy for the same particle with energy B. Under hypoxic conditions, the Do was 6 Gy for A and 1.5 Gy for B. Which of the following statements best describes the relationship between the two radiations? The OER for energy A is : [energyA] The OER for energy B is: [energyB] Radiation A has a higher LET than energy B [LET] For a given dose of radiation B, fractionating the dose would not differ markedly in the amount of cell killing as a that produced from a single dose of radiation [fractionation] Radiation B will cause greater cell damage than Radiation A [damage]
