Radiation Safety Course

Lesson 1 • Radiation Sources and Origins

Identifies natural and artificial radiation sources encountered in occupational settings. Contextualises source types for later hazard assessment.

Lesson 2 • Types of Ionizing Radiation

Distinguishes alpha, beta, gamma, X-ray, and neutron radiation. Links each type to its penetration depth and biological relevance.

Lesson 3 • Atomic Structure and Radioactivity

Covers atomic nucleus composition, isotopes, and decay processes. Provides the physical basis for understanding why radiation is emitted.

Lesson 1 • Absorbed Dose and Dose Rate

Introduces absorbed dose in gray and rad, and dose rate calculations. Connects energy deposition to measurable physical quantities.

Lesson 2 • Collective Dose and Dose Limits

Explains collective dose and regulatory occupational and public dose limits. Prepares students to evaluate compliance with exposure standards.

Lesson 3 • Equivalent and Effective Dose

Applies radiation and tissue weighting factors to derive biologically meaningful dose. Enables comparison of doses from different radiation types.

Lesson 1 • Cellular Mechanisms of Radiation Damage

Describes direct and indirect DNA damage pathways and repair mechanisms. Grounds biological risk assessment in molecular radiobiology.

Lesson 2 • Radiosensitivity and Modifying Factors

Examines how age, cell type, oxygen level, and dose rate alter radiation response. Enables risk stratification for diverse worker populations.

Lesson 3 • Deterministic Radiation Effects

Covers threshold-dependent tissue reactions including erythema, cataracts, and acute radiation syndrome. Identifies dose thresholds for clinical significance.

Lesson 1 • Principles of Radiation Detection

Explains ionization, scintillation, and solid-state detection mechanisms. Provides the physical basis for choosing instruments in specific scenarios.

Lesson 2 • Measurement Quality and Uncertainty

Addresses calibration, background correction, and statistical uncertainty in measurements. Ensures students produce defensible, traceable measurement results.

Lesson 3 • Personal Dosimetry Devices

Describes thermoluminescent, optically stimulated, and electronic personal dosimeters. Links dosimeter selection to regulatory dose record requirements.

Lesson 1 • Workplace Zoning and Access Control

Establishes supervised, controlled, and exclusion zone classifications and their requirements. Prepares students to design and enforce area access programmes.

Lesson 2 • Internal Contamination Control

Covers inhalation, ingestion, and wound pathways for internal dose and their prevention. Connects contamination control to committed effective dose reduction.

Lesson 3 • Justification and Optimisation Principles

Defines justification of practices and optimisation of protection using ALARA. Establishes the ethical and regulatory framework for all protection decisions.

Lesson 1 • Regulatory Framework Overview

Surveys international and national regulatory bodies, licensing, and authorisation systems. Positions students to navigate regulatory requirements in their work context.

Lesson 2 • Incident Reporting and Investigation

Defines reportable events, investigation methods, and corrective action documentation. Prepares students to respond to and learn from radiation incidents.

Lesson 3 • Radiation Safety Programme Elements

Identifies mandatory programme components including written procedures, training, and audits. Enables students to build or evaluate a complete safety programme.

Lesson 1 • Emergency Planning and Preparedness

Covers emergency plan components, roles, and exercise requirements. Establishes the organisational foundation for effective emergency response.

Lesson 2 • Protective Actions for Workers and Public

Applies sheltering, evacuation, and stable iodine distribution as protective actions. Trains students to select and implement actions based on dose projections.

Lesson 3 • Emergency Dose Assessment

Uses field measurements and source term data to estimate doses during emergencies. Supports real-time protective action decision-making.

Lesson 1 • Radioactive Waste Classification

Defines low-, intermediate-, and high-level waste categories and their regulatory criteria. Enables correct waste stream segregation from the point of generation.

Lesson 2 • Waste Packaging and Transportation

Covers waste packaging standards, labelling, and transport regulations for radioactive materials. Ensures safe and compliant movement of waste off-site.

Lesson 3 • Waste Minimisation and Segregation

Applies source reduction, segregation, and volume reduction techniques. Reduces disposal costs and regulatory burden through proactive waste management.
