1) Primary dosimeters should be worn on the chest area. This area is on or

between the neck and the waist. Radiological control procedures or work

authorizations may also identify proper placement.

2) Supplement dosimeters are worn in accordance with site policy. This includes

pocket, electronic dosimeters, extremity dosimetry, or multiple dosimeter sets.

c. Take proper actions if dosimeter is lost, damaged, contaminated, or off-scale. If in

an area controlled for radiological purposes, take the following actions:

1) Place work activities in a safe condition.

2) Alert others.

3) Immediately exit the area.

4) Notify radiological control personnel.

d. Store the dosimeter in the proper storage location.

dosimeters may be restricted from continued radiological work.

Dosimeters issued from the permanent work site cannot be worn at another site.

B. Internal Monitoring

Whole body counters, chest counters, and/or bioassay samples may be used to monitor

may be determined. An internal dose estimate may be performed based on these

measurements.
