10. Exposure of the Patient from SLN-Diagnostic

11. Conclusion
The dose to the personnel involved in intra- and post-operative diagnostic of the SLN is well beyond 1mSv
Instruction and training of the personnel according to method and radiation protection is nevertheless highly recommended
The dose to the patient is justified by the benefit from minimization of surgery and improved diagnostic of lymph node metastases
