  1. The
    dose-response relationship for radiation-induced cataracts is_____,
    threshold
    nonlinear
  2. threshold dose for radiation
    induced cataracts is 200 rad or ___ Gy
    2
  3. most radiosensitive area of head is the eyes – is the
    cornea
  4. Studies of large numbers of people exposed to a toxic substances
    Epidemiologic studies
  5. Epidemiologic studies of people exposed to radiation are difficult because
    (1) the dose usually is not known but is presumed to be low, and
    (2) the frequency of response is very low. Consequently, the results of radiation epidemiologic studies do not convey the statistical accuracy associated with observations of stochastic radiation effect
    (3) Both
    3
  6. The study of chromosome damage from radiation exposure is called
    cytogenetics.
  7. What
    is the dose response relationship for radiation induced leukemia
    linear and nonthreshold
  8. Radiation
    induced skin cancer is not a threshold dose relationship
    True or false
    False
  9. Low-dose, chronic irradiation impairs fertility.
    True or False
    False
  10. When is the most
    radiosensitive time of pregnancy?
    the first trimester
  11. What is the all or nothing
    response in regards to exposure during pregnancy?
    Either a radiation-induced abortion occurs, or the pregnancy is carried to term with no ill effect.
  12. …as dose increases, the severity/harshness/seriousness of a specific effect increases this is what kind of effect
    Non-Stochastic effects 
  13. The stochastic dose-response relationship is linear.
    True or False
    True
  14. What
    are the 4 somatic and genetic damage factors?
    • 1- the quantity of iodoizing radiation patient is exposed to
    • 2-the ability of ionizing radiation to cause ionization of tissue
    • 3- Amount of body area exposed
    • 4- BODY PART EXPOSED
  15. Late effects that can be directly related to the dose received and occur months or years after a high-level radiation exposure are classified as
    late nonstochastic (deterministic) somatic effects.
  16.  ______are those observed within 3 months of exposure and are associated with relatively high radiation doses (greater than 50 cGy).
    Short-term effects 
  17. ______ effects are those that affect the body of the irradiated individual directly
    Somatic
  18. ______ effects occur as a result of damage to the reproductive cells of the irradiated person and may be observed as defects in the children or grandchildren of the irradiated individual.
    genetic
  19. ________ effects occur only after a certain amount of exposure has been received, and the severity of the effect depends on the dose.
    Nonstochastic
  20. _______ radiation effects are short-term somatic effects associated with high-dose exposure. They are predictable and their severity is dose dependent.
    Nonstochastic
  21. _______ radiation effects are random long-term effects associated with low-dose exposure. Likelihood is dose dependent, and the severity of the effect is random.
    Stochastic
