Nuclear Medicine Laboratories – Procedures and Security Requirements

Nuclear Medicine Facilities in Germany: Procedures and Security Requirements

What is Nuclear Medicine? Nuclear medicine is a medical specialty that uses radioactive substances to diagnose and treat diseases. A patient receives a small amount of a radiopharmaceutical, and its distribution in the body is tracked using imaging devices such as SPECT or PET-CT.

Key examinations performed in nuclear medicine facilities:

• PET-CT: Early cancer detection and assessment of spread

• Thyroid scintigraphy (Schilddrüsenszintigraphie): Evaluation of thyroid function

• Bone scintigraphy (Knochenszintigrafie): Detection of bone metastases

• Myocardial scintigraphy (Myokardszintigrafie): Assessment of cardiac perfusion

Strict safety requirements under German Radiation Protection Law (Strahlenschutzgesetz):

1. Radiation protection: Lead-shielded rooms, radiation detectors, limited exposure time for patients and staff

2. Medical staff training: Certified radiation protection courses, regular medical check-ups

3. Handling radioactive waste: Temporary storage until safe decay, disposal via approved environmental methods

4. Patient monitoring after therapy: Isolation in certain treatments (e.g., Iod-131), detailed instructions after discharge

Legal and regulatory aspects: Facilities are monitored by the Federal Office for Radiation Protection (BfS), local health authorities, and nuclear agencies in special cases. Each center requires an operating license specifying materials, quantities, and safety systems.

Important notes for patients:

• Inform doctor if pregnant, breastfeeding, with kidney failure, or recent radiation exam

• May need to stop certain medications or arrive fasting depending on test type
