    5gy 500 rad
  6. How long does the prodromal stage of acute radiation syndrome generally last?
    A few hours to several days
  7. What can happen to individuals who survive acute radiation syndrome?
    Selected Answer: The effects of radiation exposure can result in both cancers and genetic damage
  8. How does a very high radiation dose affect stem cells?
    Selected Answer: Permanent decrease
  9. What happens to the recovery rate of bone marrow as the dose of radiation increases?
    Selected Answer: The recovery time increases
  10. How does the size of a radiation dose affect mean survival time?
    As the dose increases, the mean survival time decreases
  11. At what dose does hematopoietic syndrome begin?

  12. What generally happens to bone marrow when it is exposed to a radiation dose of less than 1 Gy (100 rad)?
    Short-term damage, with recovery within a few weeks
  13. What are the most radiosensitive white blood cells in the human body?
  14. What is the length of time between radiation exposure and death from cerebrovascular syndrome?
    From hours up to 2 to 3 days
  15. If someone is exposed to a 1 Gy (100 rad) whole-body dose of ionizing radiation, what will be the result?
    Illness, but death will not normally occur
  16. What syndrome most likely occurs when a person is exposed to 1 to 10 Gy (100 to 1000 rad) of ionizing radiation?
    Hematopoietic syndrome
