LESSON 2
PRACTICE EXERCISE
The following items will test your grasp of the material covered in this lesson. There is only one correct
answer for each item. When you complete the exercise, check your answer with the answer key that
follows. If you answer any item incorrectly, study again that part of the lesson which contains the
portion involved.
Situation: In order to accomplish your mission, you must correctly compute the total dose of radiation
in the area of concern. This will allow the crossing of the fallout area without risk of casualties.
1.
Which nuclear data is required to compute the total dose of radiation using the total dose (fallout)
nomogram?
A.
Dose rates averaged
B.
Time of burst
C.
Dose rate referenced to H + 1
D.
Yield of the weapon
2.
What is the purpose of the index scale on the total dose (fallout) nomogram?
A.
To determine the total dose for nonstandard decay radiation
B.
As a pivoting point between the Te, Ts, R1 and D scales
C.
As a conversion scale for transmission factors
D.
To compensate for decay of radiation
3.
The total dose of radiation received by personnel crossing a fallout area is calculated using the
total dose nomogram by converting the maximum dose rate to which item?
A.
A transmission factor
B.
An average dose rate
C.
An adjusted time of stay
D.
A correlation factor
