Lesson 2/Practice Exercise
While assigned to an NBCE, you are in charge of developing a plan for a radiological survey.
The main area of interest is a route over which a mechanized infantry company must travel to
reach its objective. The company is to start across the route at 0700 tomorrow if the dose rates
will not be excessive. The time is now 2300. Which type of survey will you plan?
Which description best fits the course-leg survey technique?
A ground survey technique in which readings are taken at preselected dose-rates along a
An aerial survey technique in which the pilot flies a straight line between two terrain
features and readings are taken at specific intervals
A combination of the route and point techniques
An aerial survey where the pilot lands at selected points of operational interest so
readings can be taken
In which ground radiological survey technique are recordings made at selected distance intervals
between check points?
The area of interest for a radiological survey is entirely within the area of a subordinate unit.
Which method of control should be used?
Control by phases
A nuclear detonation occurred at 0700 and the unshielded ground dose rare at 1045 is 145
cGy(rad)/hr. What was the unshielded ground dose rate at H + 1 if the decay exponent is 1.0?
