PLOT NORMALIZED DATA AND PREPARE NBC 5 (NUCLEAR)
Critical Task: 031-506-3042
In this lesson you will learn to plot normalized data and prepare NBC 5 (nuclear) reports.
TERMINAL LEARNING OBJECTIVE:
You will plot normalized data and prepare NBC 5 (nuclear) reports.
You will be given information about and illustrations of the procedures for plotting
normalized nuclear data, constructing radiological contour lines, and preparing
NBC 5 (nuclear) reports.
You will demonstrate competency of the task skills and knowledge by responding
to the multiple-choice test covering the procedures for plotting normalized data and
preparing NBC 5 (nuclear) reports.
The material contained in this lesson was derived from FM 3-3-1, STP 3-54B34-
SM-TG, and STANAG 2103.
Once reported radiation dose rates have been normalized, they must be plotted on the SITMAP. The
contour lines connecting locations of equal radiation are constructed. Where there are no dose rate
readings at a specific location, you must be able to interpolate between known dose rates. After plotting
dose rate information and constructing the contour lines, you must be able to prepare an NBC 5 (nuclear)
report that, when plotted by receiving units, will outline those areas contaminated with significant levels

6-1. General. The radiological SITMAP shows only
the minimum-essential information about detected
and identified areas of contamination necessary to allow a visual interpretation of the contamination
situation. Each contaminated area is depicted on the map by a pattern of dose rate contour lines and a few
key dose rates for points, routes, or areas of particular concern. This information is developed by plotting
monitoring and survey dose rate contour information which has been corrected to unshielded ground dose
rates at the reference time (normally H + 1) for the particular pattern. All monitoring and survey
