Airport X-Ray Screening Course

Lesson 1 • Regulatory Framework and Standards

Introduces the global regulatory environment governing airport screening. Students identify how international standards translate into operational requirements.

Lesson 2 • Aviation Security Overview

Covers the history and rationale of aviation security screening programmes. Connects threat evolution to the development of modern screening protocols.

Lesson 3 • Screening Checkpoint Layout

Describes the physical design and workflow of a standard screening checkpoint. Students understand how layout influences screening efficiency and security outcomes.

Lesson 1 • Principles of X-Ray Imaging

Explains how X-ray radiation interacts with matter to produce screening images. Provides the physics foundation needed to interpret image characteristics accurately.

Lesson 2 • Radiation Safety for Operators

Addresses occupational radiation exposure limits and protective measures for screeners. Ensures students apply safe working practices around X-ray equipment at all times.

Lesson 3 • Equipment Controls and Interface

Trains students on operator controls, display settings, and image manipulation tools. Proficiency with the interface directly supports accurate and efficient image analysis.

Lesson 4 • Equipment Maintenance and Serviceability

Covers daily checks, fault recognition, and escalation procedures for X-ray equipment. Students learn to confirm equipment is fit for operational use before each shift.

Lesson 1 • Colour Coding in X-Ray Images

Explains the standard colour palette used to represent material categories in X-ray images. Students associate colours with organic, inorganic, and metallic material types.

Lesson 2 • Density and Penetration Cues

Teaches how image brightness and darkness indicate material density and X-ray penetration. Students use density cues to distinguish between benign and potentially threatening items.

Lesson 3 • Superimposition and Clutter

Addresses the challenge of interpreting images where objects overlap or obscure each other. Students apply systematic viewing strategies to resolve cluttered image areas.

Lesson 1 • Categories of Prohibited Items

Defines the classification of prohibited items by threat level and item type. Students understand which items are absolutely prohibited versus conditionally restricted.

Lesson 2 • Firearms and Weapons Recognition

Develops recognition of firearms, ammunition, and improvised weapons in X-ray images. Students identify key visual signatures regardless of orientation or partial concealment.

Lesson 3 • Concealment Techniques and Countermeasures

Examines methods used to hide prohibited items within baggage and on persons. Students develop strategies to detect items despite deliberate concealment attempts.

Lesson 4 • Explosive Device Recognition

Covers the visual components of improvised explosive devices and their X-ray signatures. Students learn to identify power sources, initiators, and main charge indicators.

Lesson 1 • Decision-Making Under Time Pressure

Addresses the cognitive demands of making accurate screening decisions within operational time limits. Students apply decision frameworks that balance speed with thoroughness.

Lesson 2 • Threat Image Projection Training

Explains the use of threat image projection systems to maintain and measure screener detection performance. Students understand TIP protocols and performance feedback loops.

Lesson 3 • Managing Cognitive Bias in Screening

Identifies common cognitive biases that degrade screener detection accuracy over time. Students apply bias-mitigation strategies to maintain consistent performance.

Lesson 1 • Passenger communication during alarms

Addresses professional communication with passengers during alarm resolution to reduce tension. Students apply de-escalation language whilst maintaining security control.

Lesson 2 • Physical bag search techniques

Trains systematic hand-search methods for carry-on and checked baggage following an alarm. Students apply search sequences that ensure thorough coverage without damage.

Lesson 3 • Explosive trace detection integration

Explains how explosive trace detection complements X-ray screening during alarm resolution. Students apply ETD swabbing protocols to confirm or rule out explosive residue.

Lesson 4 • Alarm classification and prioritisation

Teaches students to classify alarms by threat level and determine the appropriate response. Correct prioritisation prevents both under-reaction and unnecessary disruption.

Lesson 1 • Continuous training and recertification

Outlines ongoing training requirements and recertification cycles for certified screeners. Students understand how continuous training maintains and advances their competency level.

Lesson 2 • Covert testing and compliance checks

Explains the role of covert testing in validating real-world screening effectiveness. Students understand testing protocols and how results drive corrective action.

Lesson 3 • Performance standards and metrics

Defines the key performance indicators used to evaluate screener and checkpoint effectiveness. Students interpret performance data to identify strengths and improvement areas.

Lesson 1 • Screening passengers with special needs

Covers adapted screening procedures for passengers with disabilities, medical devices, and mobility aids. Students apply respectful, compliant procedures without compromising security.

Lesson 2 • High-risk and selectee screening

Addresses enhanced screening procedures applied to selectee and high-risk passengers. Students execute additional screening measures with precision and professionalism.

Lesson 3 • Screening cargo and oversized items

Extends screening skills to non-standard items including cargo, sports equipment, and large bags. Students adapt search techniques to items that challenge standard equipment limits.

Lesson 4 • Responding to security incidents

Prepares students to respond effectively when a genuine threat is identified at the checkpoint. Students follow emergency protocols whilst maintaining checkpoint control and safety.
