Question 1

Which of the following statements concerning the 1979 nuclear reactor accident at TMI-2 is not true?

Accepted Answer

A)  Many excess cancer deaths have been predicted to occur in the 2 million people living within 50 miles of the plant at the time of the accident.
B)  During the time of the accident,if persons living within a 100-mile radius of the nuclear power plant received an average radiation exposure of 15 microgray,and this dose is used as the population dose,then no more than two additional resulting cancer deaths can be predicted in the exposed inhabitants as a consequence of radiation exposure.
C)  The average dose received by the exposed population living within a 50-mile radius of the TMI nuclear power station at the time of the accident was determined to be 0.08 mSv,which is well below the average annual background level.
D)  No melt-through of the reactor vessel resulted during the accident.E) A) and B)
F) C) and D)
