Part 11:  Radiation Dosimetry

1.      Marie Curie's Professor proudly carried in an inside pocket of his coat a glass vial containing the first sample of radium-226 ever produced; shortly thereafter, the first radiation burn was documented. This skin burn was caused by

a.      The potent 4.8 MeV alpha particles emitted by this isotope

b.      The gamma rays accompanying the alpha decay

c.      Cerenkov Radiation

d.      0.005 keV X-rays

2. Irradiation of the juvenile thyroid has been associated with an increased risk of developing

a.      thyroid carcinoma and parathyroid adenomas

b.      hypothyroidism

c.      hyperthyroidism

d.      aplastic anemia

3. The ALARA Concept, implemented in the late 1970's, has contributed to

a.         A reduction in the cost of radiopharmaceuticals

b.         An overall reduction in dose to radiation workers.

c.         Increased compliance with continuing education requirements

d.         Increased availability of new radiopharmaceuticals

4. In any given year, a radiation worker may receive a whole body dose of

a.      0.5 R

b.      1 R

c.      5 R

d.      10 R

e.      50 R

5. In any given year, family members of a radiation worker may receive a whole body dose of

a.      1 R

b.      0.5 R

c.      5 R

d.      10 R

e.      50 R
