Lesson 2/Learning Event 8
The NBC 5 (Nuclear) Report is a report of known actual radiological contamination. The report consists
of two parts, the heading and the body. The body of the report consists of lines ALFA, OSCAR,
TANGO, UNIFORM, VICTOR, WHISKEY, and XRAY.
The information in the heading of the NBC 5 (Nuclear) Report consists of the following
PRECEDENCE: The precedence of the NBC 5 (Nuclear) Report is IMMEDIATE.
DATE/TIME: The date/time group in the heading is the date and time that the message is sent. It must
be designated whether local or ZULU time is used.
SECURITY CLASSIFICATION: Normally the NBC 5 (Nuclear) Report will be UNCLASSIFIED.
FROM: This line will identify the agency that prepared the report.
TO: This line will identify those agencies designated to receive the report.
TYPE OF REPORT: This line will identify this report as an NBC 5 (Nuclear) Report.
The body of the NBC 5 (Nuclear) Report contains the following information by line.
ALFA: This line contains the strike serial number assigned by the NBCE to the nuclear burst that
created the contamination.
OSCAR and TANGO: These lines contain the date and time of the appropriate reference time used.
When the contamination arises from a single enemy or unidentified burst the dose rate always refers to
H + 1 hour, and line TANGO is used. When there have been several detonations at different times or on
different days and no single H + 1 hour is possible, the dose rates are reported as at a specified time,
using line OSCAR. Lines OSCAR and TANGO are, therefore, alternative and cannot both be used in
the same report.
UNIFORM: 1,000 cGy(rad)/hr contour line co-ordinates.
VICTOR: 300 cGy(rad)/hr contour line co-ordinates.
WHISKEY: 100 cGy(rad)/hr contour line co-ordinates.
XRAY: 20 cGy(rad)/hr contour line co-ordinates.
