Reactor Safeguards Licensing Branch FROM:
Robert A. Clark, Chief Reactor Safeguards Licensing Branch, DDR
SUBJECT:
PERFORMANCE OF METAL DETECTION DEVICES - REVIEW GUIDELINES #3, REVISION 1 All licensees are required to search individuals entering the protected area for firearts.
This search is normally conducted by electronic metal detection devices.
Enclosed is an acceptable standardized procedure utili:ing four specified tett weapons.
However, this is not to imply that this is the only acceptable test rethod that can be used to assure proper operation of the devices and that the licer,see must purchase four weapons of the type listed. This procedure is designed to detect those weapons most c0cconly found anc covers the spctrum of metal, weight, density, plating, size and shape found in those types of handguns.
Other test procedures using test samples other than the type of handgun listed that can demonstrate they can_de_tect_the.. minim _um standard of 8 oz.,1/2 lb., or 227 arams of nonferrous metal at the same detection rate for walk-tNough Tnd hand-held d Wices as with test weapons will be ac:eptable.

Ea:h time tne devi:e is turned off er maintained it must be tested a.

If the unit is never turned off, it must be tested at least once every seven cays.

a.
Assure tnat ne dete: tion device is in proper working order._
b.
With the devi:e appr:ximately two to four in:nes from the sebject, sloily pass tne devi:e Over tne entire body with the detect on loop parallel with the body, front and back. Then pass the cevice l,
slowly ever the ar s and legs, front, back anc sides. Farticu.x-attention sh uld be paid to asist, groin, armoit, and ankle area.
With practice, a thcrougn search can be made in one minute. Hand-carried outer garments will be sear:hed by hand.
Sags and parcels of any si:e will not te searched using a hard-held weapon detection
[
device.
If unit alacs, it ir.dicates that retal is resent in a given area.
