Overview
EN 12198-3:2002+A1:2008 - Safety of machinery: Assessment and reduction of risks arising from radiation emitted by machinery - Part 3: Reduction of radiation by attenuation or screening (CEN) provides a structured design strategy to help manufacturers reduce radiation flux from machines by means of attenuation and screening. It complements Part 1 (general risk assessment) and Part 2 (measurement procedures) and applies to machinery as defined by EN 292. This Type B standard supports essential requirements of relevant EU machinery directives and is intended to be used where radiation emissions present a hazard.
Key Topics and Requirements
- Design strategy & procedure: An 11‑step iterative process for reducing radiation emissions, including setting design targets, source characterization, shield design, prototyping, measurement (per EN 12198-2), verification and user documentation.
- Shield types and definitions: Clarifies terminology such as shield / attenuator, protection shield (for people/equipment), selective shield (filters by energy/kind) and shadow shield (partial enclosure to block specific directions).
- Source characterization: Requirements to assess number of sources, spectra, intensity, geometry (point, linear, cylindrical, spherical), enclosure state, functional life, and mixed radiation types.
- Beam geometry and access control: Guidance to minimize field size and beam path, enclose beams where possible, design access points to avoid leakage, and consider guards that both attenuate and prevent access.
- Material and environmental review: Selection criteria for attenuating materials (chemical composition, stability under irradiation, toxicity, machinability, flammability, weight, mechanical properties) and assessment of environmental/operational conditions (temperature, humidity, dust, vibration, atmospheres).
- Design requirements: Considerations for source positioning, mounting, penetrations, movements, interlocks, and maintenance accessibility to ensure shielding remains effective throughout machine life.
- Verification and documentation: Prototype manufacture, measurement verification per Part 2, iteration if targets are not met, and preparation of user documentation and safety information.
Practical Applications & Who Uses It
- Machine manufacturers and designers developing equipment that emits radiation (e.g., industrial radiography, lasers, high‑voltage equipment, certain diagnostic/processing machinery).
- Safety and compliance engineers conducting risk assessment, selecting shielding solutions, or preparing CE conformity documentation.
- Maintenance teams and integrators who implement access points, interlocks and shielding components safely.
- Notified bodies and regulators verifying compliance with EU machinery directives and national radiation protection limits.
Keywords: EN 12198-3, safety of machinery, radiation shielding, attenuation, screening, CEN standard, machine design, radiation protection, risk assessment.
