Which of the following items would most likely NOT trigger a standard walk-through magnetometer alarm?
Answer: Ceramic handgun
Ceramic handguns contain minimal metal components and may not trigger a standard magnetometer, making secondary screening methods critical.
During X-ray screening, an operator notices an image that appears to show overlapping items making a suspicious area difficult to interpret. What should the operator do?
Answer: Use image enhancement tools and/or request the bag be opened for physical inspection
When X-ray images are unclear due to overlapping items, operators should use enhancement tools and request a physical inspection to resolve the ambiguity.
What is the primary purpose of conducting a 'resolution search' after a walk-through magnetometer alarm?
Answer: To determine whether the alarm was caused by a prohibited item or innocent metal object
A resolution search determines whether the alarm source is a legitimate prohibited item or an innocent object like jewelry, keys, or a medical implant.
Which factor would MOST likely cause an increase in false alarms on a walk-through magnetometer?
Answer: Sensitivity set too high
Setting magnetometer sensitivity too high increases false positives as it detects smaller and less threatening metal objects like underwire bras, snaps, and coins.
A subject passes through the magnetometer without alarming, but an officer observes a suspicious bulge in the subject's waistband. What should the officer do?
Answer: Conduct additional screening including a wand check or pat-down of the area
A visual observation of a suspicious bulge warrants additional screening even after the magnetometer clears, because non-metallic weapons won't trigger the device.
Which action is considered a best practice when a subject claims a magnetometer alarm is caused by a medical implant?
Answer: Use a handheld wand or alternate screening method to clear the subject while being sensitive to their condition
Medical implant claims should be handled with sensitivity, using alternate screening such as a wand check or pat-down to clear the subject without requiring documentation.
In courthouse X-ray screening, what does a dense black image area typically indicate about an object's material?
Answer: Highly dense metal such as lead or steel
Very dense materials like lead, steel, and thick metal components appear as nearly black or very dark areas in X-ray images due to high X-ray absorption.
