Full title and description

DIN 6812:2021-06 — Medical X‑ray equipment up to 300 kV: Rules of construction for structural radiation protection. (German title: Medizinische Röntgenanlagen bis 300 kV – Regeln für die Auslegung des baulichen Strahlenschutzes). The document provides technical rules and calculation guidance for designing fixed structural shielding for medical X‑ray installations with rated voltages up to 300 kV.

Abstract

This standard specifies requirements and practical rules for the planning and dimensioning of building‑related (structural) radiation protection for diagnostic and therapeutic X‑ray equipment with nominal voltages up to 300 kV. It covers principles for barrier design, occupancy and use factors, calculation methods for transmitted dose, and provisions for alterations to existing installations to ensure protection of persons inside the X‑ray room and in adjacent areas.

Scope

Applies to the erection and structural shielding design of medical X‑ray installations with nominal voltages up to 300 kV. The standard is intended for the dimensioning of building‑integrated protective measures (walls, doors, windows, ceilings, floors) and also applies to structural changes of existing installations. Its primary focus is the protection of persons who are in the X‑ray room or in neighboring areas while the equipment is operating.

Key topics and requirements

• Principles and objectives of structural (building) radiation protection for medical X‑ray facilities.
• Calculation methods for transmitted dose through barriers and recommended safety margins.
• Occupancy and use factors for adjacent areas and zoning of controlled / supervised areas.
• Recommended barrier materials, lead equivalence guidance and minimum thicknesses for typical situations.
• Design and specification of doors, windows, penetrations and service ducts to maintain shielding integrity.
• Requirements for alterations to existing installations and verification/testing after construction.
• Alignment with applicable German radiation protection legislation and regulatory updates incorporated in the 2021 revision.

Typical use and users

Used by hospital planners, medical‑physics experts, radiation protection officers, architects and building engineers involved in healthcare facility design, manufacturers/suppliers of shielding solutions, and regulatory bodies responsible for inspection and approval of X‑ray rooms. The standard is a practical reference for designers performing shielding calculations and for project teams implementing compliant room constructions.

Related standards

Commonly used alongside international and European standards for medical equipment and protective devices, and related DIN standards for shielding and radiological practice. Examples include the IEC/EN medical equipment series (IEC 60601 family), EN/IEC standards on protective devices against diagnostic X‑radiation (IEC/EN 61331 series), and national DIN documents addressing shielding calculations and nuclear medicine practice (e.g., DIN 6844‑3 and related DIN shielding/door/glazing standards). These documents are often cross‑referenced for measurement methods, protective apparel, and device safety requirements.

FAQ

Q: What is this standard?

A: DIN 6812:2021‑06 is the DIN technical standard that sets out rules for the constructional (structural) radiation protection of medical X‑ray equipment installations with rated voltages up to 300 kV.

Q: What does it cover?

A: It covers planning and calculation methods for building‑related shielding (walls, doors, windows, ceilings, floors), occupancy/use factors, material guidance and provisions for alterations to existing X‑ray installations so that persons in the X‑ray room and adjacent areas are adequately protected.

Q: Who typically uses it?

A: Hospital planners, medical physicists, radiation protection officers, architects, building engineers, shielding manufacturers and regulatory inspectors use this standard when designing, modifying or approving X‑ray rooms.

Q: Is it current or superseded?

A: The 2021‑06 edition is the current DIN edition published on 1 June 2021 and it replaces the 2013 edition (DIN 6812:2013‑06). No later DIN replacement was published as of the 2021 edition’s distributor listings. Users should verify before use whether a newer edition or amendment exists at the time of their project.

Q: Is it part of a series?

A: DIN 6812 is a stand‑alone standard focused on structural shielding for medical X‑ray equipment; however, it is routinely used together with other medical‑equipment and radiation‑protection standards (IEC/EN 60601 family, IEC/EN 61331 series, and related DIN shielding standards) to achieve a complete compliance and safety solution.

Q: What are the key keywords?

A: Medical X‑ray, structural radiation protection, shielding design, barrier calculation, occupancy factor, lead equivalence, X‑ray room construction.
