in a floor or other nearby material that could cause constant alarms unless the 

detector’s sensitivity is turned down.

• The body scan should be performed each time in the same pattern so 

that the operator always knows what parts of the body still need scanning. A 

sample routine is illustrated on page 18.

1. Ask the scannee to place all carried items, plus any caps or headgear on 

a table (procedures for manual search of baggage are not covered in this text). 

The scannee should stand with his or her feet about 18 inches apart, facing 

away from the table and about 2 feet in front of it. Footprints outlined on the 

floor or drawn on a mat can greatly help position the scannee properly. Ask the 

scannee to hold his or her arms out to the sides, parallel to the floor.

2. Quickly run the handheld detector across some piece of conductive 

material on your own body, such as a belt buckle. The ensuing squeal of the 

detector will assure you that the scanner is still operating properly.

3. Start at the top of one shoulder of the scannee. With the paddle of the 

detector held horizontally and parallel to the front of the body, sweep down 

one side of the front of the torso, down the leg to the ankle, then move to the 

other ankle and sweep back up the front of this opposite leg and torso, ending 

with the opposite shoulder. (If a particular detector’s detection paddle is less 

than half the width of the average body, or if a particular body is wider than 

twice the width of the detection paddle, the pattern will have to be modified to 

achieve adequate coverage).

4. Sweep the detector paddle over the outside top of the arm from the top 

of the shoulder to the bottom of the wrist, then up the inside of the arm to the 

armpit. Sweep down that side of the body to the ankle, then up the inside of 

that leg and down the inside of the opposite leg, then back up the other leg 

from the ankle to the underarm. Repeat the sweep of the inside and outside of 

this arm. Note that it would be particularly important to avoid touching the 

paddle up against the scannee’s body when scanning up and down between 

the legs.

5. Ask the scannee to turn around. (Arms can be put down now). The 

pattern used to scan the front of the body should now be repeated over the 

back of the body.

6. Ask the scannee to grab the edge of the table for support, then to lift 

one foot up in back of him or herself. Scan across the bottom of the shoe. 

Repeat for the other foot. The operator should expect to hear a short squeal 

from the detector when scanning the bottom of shoes or boots with steel 

shanks or steel toes. Both shoes should cause equivalent squeals.

7. For the head area, start at the top of the forehead and scan  

around the top of the head down to the back of the neck.
