A 41-year-old man who is employed in a nuclear power plant was accidentally exposed to 35 cGy 8 days ago. As you examine him now, what clinical symptoms do you expect to observe?

(A) acute radiation syndrome
(B) cerebral syndrome
© GI syndrome
(D) hematopoietic syndrome
(E) none

Explanation:

(E) Individuals exposed to acute radiation doses between 0 and 50 cGy do not show any immediate clinical symptoms. However, lowlevel exposure may increase the likelihood of neoplasia in the future. Exposures betwee 50and 200 cGy usually produce acute radiation syndrome (choice A) characterized by fatigue, nausea, and vomiting. Hematopoietic syndrome (choice D) is characterized by leukopenia and thrombocytopenia, in addition to the clinical findings of acute radiation sickness. Exposure dosages are usually between 200 and 600 cGy. The acute mortality rate is between 20% and 50%. Exposures of 600–1000 cGy may produce mucosal ulceration, diarrhea, and electrolyte loss as part of the GI syndrome (choice C).Acute mortality rates are between 50% and 100%. The cerebral syndrome (choice B) has a 100% mortality rate and is seen with acute doses above 1000 cGy.
