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]

Which of the following statements regarding embryo and fetus irradiation exposure are true? Prenatal death and Neonatal death is a common outcome when irradiated during the 6th week post conception Severe CNS related abnormalities are possible outcomes during irradiation during the 3rd 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 pre-implantation stage will have many major congenital malformations
