Airport Security X-Ray Course

Lesson 1 • The Screening Checkpoint Environment

Describes the physical layout, personnel roles, and workflow of a passenger screening checkpoint. Contextualizes where X-ray screening fits within the broader security process.

Lesson 2 • Aviation Security Regulatory Overview

Covers the international and national bodies that govern aviation security screening. Provides the regulatory foundation all subsequent technical training depends on.

Lesson 3 • Threat Categories in Aviation Security

Introduces the categories of prohibited items and threats relevant to aviation. Builds the conceptual threat model that guides all X-ray interpretation decisions.

Lesson 1 • Principles of X-Ray Generation

Covers the physics of X-ray production and how radiation interacts with matter. Provides the scientific basis for understanding image formation in screening systems.

Lesson 2 • Image Display and Color Coding

Explains how processed X-ray data is rendered as a color-coded image on the operator monitor. Color interpretation is the primary visual tool for material classification.

Lesson 3 • Equipment Maintenance and Calibration

Covers routine checks and calibration procedures screeners perform before and during shifts. Ensures equipment operates within performance specifications for reliable imaging.

Lesson 4 • Screening System Components

Identifies the key hardware components of a conveyor-based X-ray screening system. Understanding each component helps screeners recognize equipment faults and optimize image quality.

Lesson 1 • Passenger and Baggage Radiation Exposure

Addresses the radiation dose received by passengers and their belongings during screening. Equips screeners to answer passenger questions accurately and confidently.

Lesson 2 • Ionizing Radiation Concepts

Defines ionizing radiation types and units of measurement relevant to X-ray screening. Establishes the scientific vocabulary needed for safety training and regulatory compliance.

Lesson 3 • Personal Dosimetry and Monitoring

Explains how personal dosimeters work and how screeners use monitoring data. Connects individual monitoring to regulatory dose-limit compliance.

Lesson 1 • Shape and Density Analysis

Teaches recognition of object shapes and density signatures in X-ray images. Shape and density are primary cues for distinguishing benign items from potential threats.

Lesson 2 • Benign Item Recognition

Builds a mental library of common benign items and their X-ray signatures. Rapid benign recognition reduces false alarms and improves screening throughput.

Lesson 3 • Visual Search Strategies

Introduces structured methods for scanning an X-ray image without missing areas. Systematic search is the foundation of consistent and reliable threat detection.

Lesson 4 • Alarm Resolution and Decision Making

Covers the process of resolving an image alarm through analysis and secondary screening. Connects image interpretation to the operational decision to clear or refer a bag.

Lesson 1 • Firearms and Firearm Components

Covers the X-ray signatures of handguns, rifles, and disassembled firearm parts. Recognizing partial or concealed firearms is a critical screener competency.

Lesson 2 • Bladed Weapons and Sharp Objects

Identifies knives, blades, and improvised sharp weapons in X-ray images. Thin metallic profiles require precise visual search techniques introduced in Chapter 4.

Lesson 3 • Explosive Device Recognition

Introduces the visual indicators of improvised explosive devices and their components. Screeners learn to identify wiring, power sources, and initiators as threat indicators.

Lesson 4 • Liquids, Gels, and Aerosols

Covers the X-ray appearance of liquid containers and the threat posed by liquid explosives. Connects to regulatory liquid restrictions and secondary screening protocols.

Lesson 1 • Explosive Detection Dog Support

Covers the role of explosive detection dogs as a complementary screening layer. Screeners learn how to request, coordinate, and act on canine team findings.

Lesson 2 • Explosive Trace Detection Systems

Explains how ion mobility spectrometry and related technologies detect explosive residues. Screeners learn correct swabbing technique and alarm interpretation.

Lesson 3 • Explosive Material Properties

Covers the physical and chemical properties of common explosive materials relevant to screening. Understanding material properties informs both X-ray and trace detection decisions.

Lesson 1 • Passenger Body Screening Integration

Explains how X-ray baggage screening integrates with passenger body screening methods. Coordinated procedures prevent gaps that could be exploited by threat actors.

Lesson 2 • Throughput Management and Queue Control

Balances screening accuracy with operational efficiency to manage passenger queues. Screeners learn strategies to maintain detection standards under high-volume conditions.

Lesson 3 • Hold Baggage Screening Procedures

Covers the screening of checked baggage using high-throughput X-ray systems. Addresses the unique challenges of unattended baggage and automated alarm resolution.

Lesson 4 • Cabin Baggage Screening Procedures

Details the end-to-end procedure for screening carry-on baggage at the checkpoint. Connects image interpretation skills to standardized operational steps.

Lesson 1 • Performance Metrics and Reporting

Defines the key performance indicators used to evaluate screening operations. Accurate data collection and reporting support evidence-based quality improvement.

Lesson 2 • Recurrent Training and Certification

Outlines the recurrent training cycles and certification requirements that maintain screener competency. Connects ongoing training to regulatory compliance and operational readiness.

Lesson 3 • Continuous Improvement Processes

Introduces structured methods for identifying and addressing screening performance gaps. Screeners contribute to a culture of continuous improvement through feedback and reporting.

Lesson 4 • Covert Testing and Compliance Checks

Covers regulatory covert testing programs that assess real-world screening effectiveness. Screeners understand the purpose of covert tests and how results drive corrective action.
