Lesson 2/Learning Event 1
LEARNING EVENT 1:
RECEIVE AND PROCESS
NBC 4 (NUCLEAR) REPORT
Radiological dose rates collected from radiological monitoring and surveys are forwarded to higher
headquarters and the NBCE using the NBC 4 (Nuclear) Report. The data contained in the NBC 4
(Nuclear) Report is raw data and must be processed before it is plotted on the radiological contamination
overlay or situation map. In the processing correction factors are applied as appropriate and the data is
normalized to a standard reference time.
Receive NBC 4 (Nuclear) Reports
The primary purposes of monitoring are to allow warning of all personnel of the arrival or presence of a
radiological hazard and to provide a basis for prompt action by the commander to minimize the hazard.
Warning is provided when the monitor detects the presence of a radiological hazard and reports this
information to the next higher headquarters.
The urgency of the battlefield situation will in most cases dictate how the report will be received at the
NBCE. Methods of submitting an NBC 4 (Nuclear) Report include:
Field radio.
Field telephone.
Radioteletype communications (RATT).
Courier.
Format for NBC 4 (Nuclear) Reports
The format for NBC 4 (Nuclear) Reports follows the format established in the International
Standardization Agreements (STANAG 2103 - The NBC Warning and Report System). Within this
reporting system, the NBC 4 (Nuclear) Report is used to report radiation dose-rate measurements. The
NBC 4 report is not used for chemical or biological reporting.
The NBC 4 (Nuclear) Report consists of the heading and lines QUEBEC, ROMEO, and SIERRA in the
body of the message. The information contained in each line of the body of the NBC 4 (Nuclear) Report
is as follows:
Line QUEBEC: This line contains the location where the reading was taken. The unit SOP may
require, under certain conditions, that this line be encoded.
