Which of the following statements regarding embryo and fetus irradiation exposure are true?    Severe CNS related malformations are possible outcomes during irradiation  during the 5th week post conception    Prenatal death and Neonatal death is a common outcome when irradiated  during the 11th week post conception    Permanent growth retardation may be an outcome seen later in life due to exposure during the fetal stage   An embryo that survives irradiation during the preimplantation stage will have many major congenital malformations

Which pair of human gestational stage and radiation induced effects at 1 Sv is CORRECT?

For a given biological system, the Do in the presence of O2 was determined to be 1 Gy for specific energy A and 2.5 Gy for the same particle with energy B.  Under hypoxic conditions, the Do was 4 Gy for A and 5 Gy for B.    The OER for energy A is  [OERA]   The OER for energy B is  [OERB]   Radiation A has a lower LET than energy B [LET]
