Understanding Security in Radioprotection
Germany’s regulatory landscape for ionizing radiation is comprehensive. It includes the Radiation Protection Act (Strahlenschutzgesetz), the Radiation Protection Ordinance (Strahlenschutzverordnung), DIN standards, and guidance from the Strahlenschutzkommission. These frameworks are designed to protect people and the environment from the harmful effects of radioactive substances.
However, most of these regulations focus on safe handling — from procurement and storage to processing and transport. In 2020, a new directive added a layer of security: the SEWD Directive.
What Is the SEWD Directive?
The SEWD Directive, officially titled “Guideline for Protection Against Interference or Other Third-Party Actions During Handling and Transport of Radioactive Substances”, was issued by the Federal Ministry for the Environment (BMUV).
Its purpose is clear: to prevent the criminal release or theft of radioactive materials — either on-site or during transport. It is not a public document. It is classified as VS-NfD (Verschlusssache – Nur für den Dienstgebrauch), meaning it is restricted to individuals who have passed a reliability check and completed a specialized training course.
All documents derived from the SEWD Directive are also confidential. This ensures that security measures remain protected and effective.
Does SEWD Apply to Your Facility?
If you operate with radioactive materials, you may be subject to SEWD requirements. The best approach is to proactively contact your nuclear regulatory authority. They will assess your activity inventory and determine whether SEWD implementation is necessary.
If so, they will recommend participation in a certified course. Upon successful completion, the SEWD Directive will be handed over to you — under strict confidentiality protocols.
What’s Inside the Directive?
The SEWD Directive is a structured manual for determining security classes. It evaluates:
- Activity inventory and physical form of radionuclides
- Structural features of handling areas (walls, materials, access points)
- Transport routes and security systems (locks, surveillance, fences, gates)
Each aspect is reviewed point by point. The result is a classification into security levels, which guide the necessary protective measures.
Implementation and Confidentiality
Once the security level is determined, the operator works with the regulatory authority to upgrade or adapt existing systems to meet SEWD requirements.
Operators who receive the directive are authorized to train internal personnel on handling classified information. Ideally, only a small, trusted group within the organization should be familiar with the directive and its operational implications.
