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.

SIST EN 12198-3:2003+A1:2008 표준은 기계에서 발생하는 방사선 위험을 평가하고 줄이는 데 필요한 중요한 지침을 제공하는 유럽 표준이다. 이 표준의 주요 목적은 방사선 위험에 노출될 수 있는 기계 제조업체들이 방사선을 효과적으로 차단하거나 검출할 수 있는 안전 장치 설계를 가능하게 하는 것이다. 이 표준은 EN 292에 따라 정의된 기계에 적용되며, 방사선 방출에 대한 위험 평가의 일반 원칙을 포함한 1부와 방사선 방출 측정에 대한 세부 정보를 제공하는 2부로 구성되어 있다. 이는 기계 내에서 발생할 수 있는 방사선의 종류에 따라 적절한 설계 전략을 수립하고, 기계와 그 사용 환경에서 방사선의 발생을 최소화하기 위한 실질적인 기준을 제시한다. SIST EN 12198-3:2003+A1:2008의 강점 중 하나는 다양한 유형의 방사선과 기계에 맞춰 방사선을 감소시키기 위한 차폐 및 감쇠를 통한 설계 전략을 제공한다는 점이다. 이를 통해 제조업체들은 자신의 기계에서 발생하는 방사선의 위험을 보다 효과적으로 관리할 수 있으며, 궁극적으로 작업자의 안전을 보장할 수 있는 제품을 설계할 수 있게 된다. 방사선 차단 및 감쇠와 관련된 기술적 세부 사항은 다른 표준에서 제공되지만, 이 표준은 기계의 설계 및 제조 단계에서 방사선에 대한 고려가 중요한 이유를 잘 설명하고 있다. 따라서, SIST EN 12198-3:2003+A1:2008 표준은 기계 안전성 및 방사선 위험 관리를 위한 필수적인 참고 자료로 간주된다.
The standard EN 12198-3:2002+A1:2008 addresses an essential aspect of machinery safety, specifically focusing on the assessment and reduction of risks associated with radiation emitted by machinery. This document provides a vital framework that enables manufacturers to design and implement effective safeguards against radiation hazards, ensuring both compliance with safety regulations and the protection of personnel. One of the notable strengths of this standard is its comprehensive scope, providing a clear foundation for manufacturers concerned with radiation risks. By outlining general principles of risk assessment related to radiation emission in Part 1, it establishes a methodical approach that can be adapted to various machinery types as defined by EN 292. This systematic methodology is crucial for workplaces where machinery operates in the presence of radiation, as it shows a clear commitment to safety and risk management. Part 2 of the standard enhances its relevance by offering specific details on measuring radiation emissions, while Part 3 delves into effective design strategies for reducing radiation exposure through attenuation or screening. The focus on design strategy not only aligns with modern engineering practices but also encourages innovation in creating machinery that minimizes radiation risks. Furthermore, the standard's emphasis on tailoring specific technical details for different types of radiation and machinery-in conjunction with guidance from other related standards-demonstrates an integrated approach to machinery safety. Such an approach ensures that manufacturers can develop suitable solutions that address various radiation concerns, thus enhancing workplace safety across multiple sectors. Overall, EN 12198-3:2002+A1:2008 stands out as a crucial standard in the realm of machinery safety, providing manufacturers with the necessary tools and strategies to effectively manage radiation risks through design and engineering. Its relevance is underscored by its structured method of risk assessment and its commitment to the reduction of radiation through innovative safety measures.
