STANDARD:

Identify steps to follow to supervise periodic monitoring to include ensuring operators take readings at least once per hour and recording the reading on the appropriate forms.

Area Monitoring

Monitoring provides the following:

Early warning and useful radiological information to units at all levels

Warning of hazards that might otherwise go undetected (e.g., monitoring alerts the unit to the arrival of fallout)

Information to the unit commander about the degree of hazard in the unit area

Data for development of the radiological contamination overlay at the division level

7031-503-3006 VG

Periodic Monitoring

The recurring check of a unit’s area for radiation.

Assures commander that the unit area is not contaminated.

Warns the unit if contamination arrives.

8031-503-3006 VG

Continuous Monitoring

The surveillance for radiation in the unit area or position.

An around-the-clock check for radiation in the unit’s area.

9031-503-3006 VG

Direct Monitoring

The simplest and most precise type of monitoring.

Consists of unshielded dose rate readings.

Used when conditions and operational exposure guidance (OEG) permit.

10031-503-3006 VG

Direct Monitoring Procedures

Step 1 (b)

360°

10 Meters

11031-503-3006 VG

Indirect Monitoring

Measures dose rates within an area shielded from radiation.

Allows the unit to measure radiation levels and still keep exposure to a minimum.

The preferred method when operating in a contaminated area.

Indirect Monitoring Procedures

Step 2 (b)

360°

Center

13031-503-3006 VG

Automatic Reports

All units in the contaminated area submit certain monitoring reports automatically.

Provide the minimum essential information for warning, hazard evaluation, and survey planning.

Sent through specified channels to reach the NBC Center (NBCC).

Nondivisional and corps units in a division area submit reports to the division NBCC.

Corps units send reports to corps NBCC.

14031-503-3006 VG

Additional Reports

In addition to automatic reports, units may be required or directed to submit other reports.

15031-503-3006 VG

Special Reports

Field standing operating procedures (FSOP)/ operations plan (OPLAN)/operational order (OPORD) and other standing instructions may establish the requirement for special NBC 4 Nuclear Reports.

16031-503-3006 VG

Increasing and Decreasing Reports

Dose rates reported on NBC 4 Nuclear Reports (line item ROMEO) followed by the words increasing or decreasing are never sent unless requested.

17031-503-3006 VG

Directed Reports

Selected units in the contaminated area will be directed to submit additional NBC 4 Nuclear Reports.

The NBCC uses these reports to evaluate a radiological contamination hazard, the decay rate of fallout, and how long this decay rate (and contamination overlay) will remain valid.

Used to determine the H-hour (if unknown) and the soil type in induced area.

18031-503-3006 VG

Series Report

Consists of dose rate readings taken at the same location at 30-minute intervals for 2 hours followed by hourly reports.

Begins after a peak dose rate has been noted at the monitor’s location.

19031-503-3006 VG

Summary Report

A Summary Report shows the radiation distribution throughout a unit’s area of responsibility.

20031-503-3006 VG

Verification Report

A unit’s response to a direct request from the NBCC.

Requested by NBCC if data are lacking from a specified location near or in the unit area.

Can be used to recheck an unusually high dose rate, a zero reading, or other abnormalities.

21031-503-3006 VG

Verification Report (cont.)

The NBCC is aware that the previously reported dose rate is no longer valid because radioactive decay will have taken place.

Not a retransmission of previously reported readings, but a check of the actual condition of the area.

22031-503-3006 VG

Correlation Factor

CF data are computed so that shielded dose rate readings can be converted to unshielded dose rate readings.
