Examines low-yield battlefield weapons, enhanced-radiation designs, and experimental configurations tested outside standard programs. Broadens understanding of test diversity.

Lesson 2 • Thermonuclear Weapon Principles

Explains fusion boosting and staged radiation implosion that enable megaton-class yields. Connects design evolution to the need for large-scale atmospheric tests.

Lesson 3 • Gun-Type and Implosion Devices

Compares the two primary fission weapon architectures, their efficiency trade-offs, and material requirements. Provides the design vocabulary used throughout testing history.

Lesson 1 • Testing Nations and Test Counts

Presents verified test totals for each nuclear state and the periods of peak activity. Establishes the quantitative baseline for comparative analysis.

Lesson 2 • Test Environments and Configurations

Distinguishes atmospheric, underground, underwater, and high-altitude test modes and their technical purposes. Explains why environment selection changed over time.

Lesson 3 • Chronology of Testing Moratoriums

Traces voluntary pauses, negotiated moratoriums, and treaty-driven test bans that punctuated the testing era. Connects political events to shifts in test frequency.

Lesson 1 • Fireball and Mushroom Cloud Dynamics

Describes thermal, blast, and radiation phases of an atmospheric burst and cloud formation mechanics. Provides the physical foundation for understanding fallout generation.

Lesson 2 • Fallout Particle Formation and Transport

Explains how soil, weapon debris, and fission products combine into fallout particles and travel globally. Links particle size to deposition timing and geography.

Lesson 3 • Historical Fallout Events and Measurements

Reviews documented high-fallout incidents, monitoring network data, and population dose reconstructions. Demonstrates how scientific understanding evolved from real events.

Lesson 1 • Transition to Underground Testing

Explains the political and scientific drivers that shifted programs from atmospheric to underground environments. Contextualizes the engineering challenges that followed.

Lesson 2 • Containment Design and Venting Events

Details stemming column design, canister placement, and the causes of accidental radioactive venting. Provides a basis for evaluating legacy contamination at test sites.

Lesson 3 • Geology and Site Selection Criteria

Covers rock type, water table depth, fault proximity, and cavity collapse risk as site selection variables. Connects geology to containment success rates.

Lesson 1 • Radiation Biology Fundamentals

Covers ionizing radiation interaction with DNA, deterministic vs. stochastic effects, and dose-response models. Provides the biological framework for interpreting health study findings.

Lesson 2 • Environmental Contamination and Site Remediation

Surveys soil, groundwater, and marine contamination at legacy test sites and the remediation approaches applied. Evaluates long-term monitoring requirements.

Lesson 3 • Military Personnel Exposure Studies

Reviews cohort studies of soldiers, sailors, and aircrews present at tests and the cancers and mortality outcomes documented. Highlights methodological challenges in occupational dose reconstruction.

Lesson 4 • Indigenous and Displaced Community Impacts

Documents forced relocations, subsistence diet contamination, and multigenerational health effects on communities at Pacific and continental test sites. Frames environmental justice dimensions.

Lesson 1 • Underground Test Limitation Agreements

Examines bilateral yield-threshold treaties, their verification protocols, and the seismic exchange arrangements that accompanied them. Connects technical verification to political trust-building.

Lesson 2 • Treaty Compliance and Verification Challenges

Reviews disputed events, ambiguous seismic signals, and the limits of remote monitoring in detecting low-yield or evasive tests. Prepares students for current nonproliferation debates.

Lesson 3 • Comprehensive Test Ban Treaty Architecture

Details the four-technology verification system, the international monitoring network, and the on-site inspection regime of the comprehensive ban. Evaluates entry-into-force challenges.

Lesson 1 • Commemoration, Memorialization, and Justice

Surveys survivor advocacy movements, compensation legislation, and memorial sites as expressions of historical accountability. Connects memory politics to ongoing policy debates.

Lesson 2 • Current Nonproliferation and Disarmament Policy

Connects testing history to active debates on stockpile modernization, new nuclear states, and disarmament obligations. Students apply historical lessons to contemporary policy scenarios.

Lesson 3 • Declassification and Historical Record

Examines the declassification process for test records, the gaps that remain, and how released documents have reshaped historical understanding. Equips students to use primary source archives.
