# Health Physics & Radiological Shielding

ALARA principles, linear no-threshold (LNT) models, point-kernel gamma/neutron attenuation ($I = I_0 e^{-\mu x}$), and dosimetry.

## Standard Operating Procedure & Methodology

### 1. Requirements Formulation & Physical Principles
Establish the mathematical and physical foundations of health physics & radiological shielding:
- Identify relevant governing standards, equations, and operational constraints.
- Formulate the system state, boundary conditions, and performance objective functions.
- Specify rigorous tolerance bands, diagnostic thresholds, and verification criteria.

### 2. Analytical & Algorithmic Workflow
1. **Input Verification**: Ingest system specifications, baseline measurements, and operational bounds.
2. **Computational Modeling**: Execute closed-form or numerical evaluations per standard engineering methodologies.
3. **Sensitivity & Stress Assessment**: Evaluate parameter variations, perturbation response, and failure modes.
4. **Safety & Compliance Check**: Validate output states against applicable industry and safety regulatory codes.

### 3. Implementation Verification Contract
Every operational execution must verify:
- Complete parameter determinism and absence of unverified assumptions.
- Boundary adherence across nominal, peak, and failure envelope states.
- Traceable audit records conforming to relevant international standards.

## Reference Architecture & Formulas
Standard governing equations, reference architectures, and diagnostic matrices are applied systematically to ensure fail-safe operational behavior and reproducible engineering outcomes.
