ENABLING LEARNING OBJECTIVE A
Action
Supervise radiation monitoring.
Conditions
Given commander's OEG and a scenario where nuclear warfare is
described, or a scenario describing DULLRAM.
Standard
IAW STP 21-24-SMCT and unit SOP.
Learning Step/Activity
a. Area Radiological Monitoring
(1)
Radiological monitoring is done routinely to determine the presence and intensity of
the residual radiation hazard. Monitoring is performed while in a stationary position.
The radiation may be from fallout or neutron-induced areas. There are two types of
radiological monitoring - periodic and continuous.
(2)
Periodic monitoring - Periodic monitoring consists of frequent checks of the unit area
for radiation. Periodic monitoring is initiated after the first use of nuclear weapons in
theater, when a unit is out of contact with higher headquarters, when ordered by
higher headquarters, or when the unit stops continuous monitoring.
(3)
(a)
During periodic monitoring, take a reading with an AN/VDR-2 RADIAC set
at least once each hour.
(b)
Unit SOPs may require more frequent readings and should provide detailed
information on monitoring procedures.
(c)
When a unit has more than one dosimeter, only one is required for periodic
monitoring.
Continuous monitoring - Continuous monitoring is the surveillance for radiation in
the unit area or position. It is an around-the-clock check for radiation in the unit’s
area. Units will initiate continuous monitoring when:
(a)
Nuclear detonation is observed, heard, or reported in their area of operations.
(b)
An NBC 3 Nuclear Report is received and the unit is in the predicted area of
contamination.
(c)
A dose rate of 1 cGyph is recorded during periodic monitoring.
60
B-6
(d)
Ordered by the unit commander.
b. Radiation Monitoring Techniques
(1)
Direct monitoring - Direct monitoring is the simplest and most precise of the
techniques.
(a)
Procedures:
 A dosimeter is used to get an unshielded dose rate.
 Determine the unshielded (outside) dose rate by standing with the
AN/VDR-2 held waist high, or 1 meter off the ground, and rotating your
body 360 degrees.
 The highest reading observed is recorded as the dose rate.
(b)
Direct monitoring is used:
 While monitoring for the initial detection or arrival of fallout.
 When in low dose rate areas.
 When determining unshielded (outside) ground dose rates for transmission
or correlation factors.
 When verifying the contamination status of a new position.
 While moving through a contaminated area on foot.
NOTE:
(2)
Computing correlation factors will be covered in ELO C of this lesson.
Indirect monitoring - Indirect monitoring is done inside shelters or vehicles. This
allows the unit to measure radiation levels and still keep exposure to a minimum.
Indirect monitoring is the preferred technique when operating in a contaminated area.
(a)
Procedure:
 At least one outside reading is necessary to determine the correlation
factor.
 Both the inside and outside readings must be taken within three minutes of
each other.
 Both readings must be taken after fallout is complete.
 Calculate the correlation factor.
(b)
Indirect monitoring is used whenever dose rates are high enough to be read
inside the shielded location. This technique reduces the exposure the operator
would get using the direct method in a high dose rate area (when dose rates
are detectable inside a shelter).
61
B-6
c. Radiation Monitoring Reports
(1)
Radiation monitoring is reported using either automatic or directed NBC 4 Nuclear
Reports. The information contained in these reports will vary depending on the word
or words included with line item ROMEO which indicates the dose rate reading.
(a)
Automatic reports - All units in the contaminated area submit certain
monitoring reports automatically.
These provide minimum essential
information for warning, hazard evaluation, and survey planning. The
purpose of establishing automatic reports is to prevent overload of
communications. In this way, units are obligated, yet limited, to certain types
of reports.
(b)
Directed reports - Selected units in contaminated areas will be directed to
submit additional reports.
NOTE:
(2)
(3)
Preparing NBC 4 Nuclear Reports will be covered in ELO B of this lesson.
There are three types of automatic reports: initial, peak and special.
(a)
An initial report is the first report sent when the unit monitor records an
outside dose rate reading of 1 or more cGyph. The word “Initial” is included
with line item ROMEO of the report.
(b)
Peak reports are sent because radiation levels will rise, peak, and then
decrease. The monitor records the highest outside dose rate reading along
with location of readings, times of readings, inside dose rate, and outside dose
rate. The information is calculated and sent as an NBC 4 Nuclear Report with
the word “Peak” included with line item ROMEO.
(c)
Special reports - These reports invite command attention to areas or
conditions of serious concern. The operational situation, unit radiation status,
and similar considerations determine the criteria for these special reports.
There are several types of directed reports.
(a)
A Series report consists of dose rate readings taken at the same location at 30minutes intervals for 2 ½ hours followed by hourly reports. Requests for these
reports come through intelligence channels. The information is sent as an
NBC 4 Nuclear Report with the word “Series” included with line item
ROMEO.
(b)
A Summary report shows the radiation distribution throughout a unit’s area of
responsibility. The locations for readings are selected by the reporting unit
according to the distribution of its elements and the extent or variety of the
area’s terrain. The defense team organizes the data into the NBC 4 Nuclear
Report with the word “Summary” included with line item ROMEO.
(c)
The Verification report is a unit’s response to a direct request from the NBCC.
62
B-6
If data is lacking from a specified location near or in the unit area, the NBCC
requests this type of report. A unit tasked with submitting a Verification
report will receive specific instructions. These will include the exact location
for the readings, why the report is requested, and details about
communications. The team will format the NBC 4 Nuclear Report with the
word “Verification” included with line item ROMEO.
d. Supervise Radiation Monitoring
(1)
Determine whether to use periodic or continuous monitoring.
(2)
Select a central point in your area where you want the operators to take readings.
Locate the grid coordinates on the map and have dosimeter operators record the
location on DA Form 1971-R or paper, whichever will be used to record the readings.
NOTE:
Recording data on DA Form 1971-R will be covered in ELO D.
(3)
Ensure the operators perform preventive maintenance checks and services (PMCS) on
the AN/VDR-2 RADIAC Set.
(4)
Determine whether operators should use the direct or indirect technique while
monitoring. The indirect method is always preferred.
(5)
For periodic monitoring direct the operators on how often to take readings (at least
once per hour or as stated in the unit SOP). Remind the operators to zero their
dosimeters before each reading to prevent significant errors caused by electronic
fluctuations.
(6)
Make sure the operators have a means of recording locations, readings, and time (DA
Form 1971-R, Radiological Data Sheet Monitoring and Point Technique, or on plain
paper). Tell the operators to record the readings and report them to you.
(7)
Spot check the operators to make sure the or AN/VDR-2 RADIAC Set are being used
correctly.
(8)
Report the data as an initial, peak or special report. For the peak reports, report other
dose rates along with CF data in accordance with the unit SOP. Put the data in the
NBC 4 Nuclear Report.
63
B-6
ENABLING LEARNING OBJECTIVE B
Action
Prepare and submit NBC 4 Nuclear Report.
Conditions
Given monitoring/survey readings, completed DA 1971-series Form
(monitoring, survey and reconnaissance data), paper, pencil, and report
format (GTA 3-6-8 or FM 3-3).
Standard
Prepare and submit NBC 4 Nuclear Report IAW FM 3-3 and unit SOP.
Learning Step/Activity
a. NBC 4 Nuclear Report
(1)
When any unit detects NBC hazards through monitoring, survey or reconnaissance,
this information is reported using an NBC 4 Report.
(2)
Separate NBC 4 Nuclear Reports are consolidated and then plotted on the tactical
map to show where the hazard exists.
(3)
The reports will contain only correlated data. The raw readings must be correlated
and reflect the true hazard (outside) for that time.
NOTE:
(4)
Correlation factors will be covered in ELO C of this lesson.
The precedence of an NBC 4 Report depends on the urgency of the report. It is
usually sent IMMEDIATE, but may be upgraded or downgraded as the situation
dictates.
b. Prepare an NBC 4 Nuclear Report
(1)
Report the heading information.
(a)
Determine precedence of report as appropriate. Precedence is usually
IMMEDIATE or according to the unit standard operating procedure (SOP).
(b)
Report date time group of message.
(c)
Report security classification as directed (normally unclassified).
64
B-6
(d)
Report your unit as sender (FROM).
(e)
Report receiving unit designation (TO).
(f)
Report type of NBC 4 as nuclear.
(2)
Report location of reading (grid coordinates) as line QUEBEC.
(3)
Report dose rate (in centigray per hour) as line ROMEO.
(4)
Certain words may be used with the dose rate on line ROMEO to describe the
circumstances. These words include Initial, Peak, Summary, Series, and Verification,
and determine what type of dose rate reading is being reported.
NOTE:
More than one word may be used on a single report.
(5)
In reconnaissance, the first contact with radiation is reported immediately.
(6)
Report the date time group of reading as line SIERRA.
c. Submit an NBC 4 Report
(1)
Submit the completed NBC 4 Nuclear Report as directed or IAW unit standard
operating procedure (SOP).
(2)
An NBC 4 Nuclear report may submitted by computer database update, electronic
facsimile, messenger, or liaison officer.
ENABLING LEARNING OBJECTIVE C
Action
Compute correlation factors.
Conditions
Given inside and outside or air and ground dose rate readings.
Standard
Compute correlation factors to the nearest hundredth IAW FM 3-3-1.
65
B-6
Learning Step/Activity
a. Purpose of Correlation Factors
Correlation factors are used to convert the reported readings taken inside the vehicle or
shelter to ground dose rates existing outside the vehicle or shelter.
NOTE:
The forward slash (/) will be used in formulas to indicate that division must take
place.
b. Calculate Correlation Factor (CF)
(1)
During radiological monitoring or survey operations, take shielded readings. At
certain locations, also take unshielded readings within three minutes of the shielded
readings. Record this information on DA Form 1971-R or 1971-1-R or as
appropriate.
NOTE:
DA Form 1971-R and DA Form 1971-1-R will be covered in ELO D of this
lesson.
(2)
Use the following formula to compute the correlation factor (CF):
OD / ID = CF
Outside dose (OD) divided by inside dose (ID) equals correlation factor (CF).
Round the answer to the nearest hundredth.
Example: A reading of 3cGyph is taken inside an M113 armored personnel carrier. Within
three minutes, an outside reading of 10cGyph is taken at the same location. What is
the correlation factor of the vehicle?
OD / ID = CF
10cGyph / 3cGyph = 3.333 = 3.33 (rounded)
The correlation factor is 3.33.
