Dr. Ulrich Stöhlker has a nuclear physics PHD from University of Gießen, Germany and was delegated to the Insitut Laue-Langevin in Grenoble, France.from 1982 until 1987. In 1987 he joined the federal office for civil protection which was later transformed to the federal office for radiation protection in 1997.
From 1997 until today he is head of the radiation monitoring unit with main responsibility in the management of the German external dose rate monitoring network with 1800 gamma dose rate measurement posts, 12 on-line aerosol monitors and 6 mobile in-situ measurement vehicles, equipped with high purity Germanium detectors. This includes:
• The organization and management of staff and laboratories at 6 different locations in Germany with 46, scientists, enginieers and technicians.
• Continuous operation of the network and monitoring systems, maintenance, calibration and QA operations.
• The design, implementation and operation of dedicated application software.
• Development of gamma analysis and nuclide identification software also suitable for embedded systems.
• Development of detectors, data loggers, communication procedures maintaining contact with several organizations.
• Development of new spectrometric gamma dose rate probes based on room temperature scintillation and semi conductor detectors in co-operation with University of Freiburg.
• Development of a low cost high performance digital multi channel analyzer in co-operation with University of Freiburg.
• Introduction of new technologies including testing and enhancement of automated and interactive procedures.
• Management and member of the on-call duty service of the German radiological surveillance system in Freiburg connected to national and international organizations.
• Between 1997 and 2001 responsible for the operation of the noble gas and trace analysis laboratories in Freiburg.
From July 2010 until July 2013: Senior radionuclide officer at the International Data Centre (IDC) of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) in Vienna:
• Responsible for development and operation of gamma spectrum analysis and beta-gamma coincidence analysis software at the IDC of CTBTO.
• Responsible for the development and operation of two mobile container-based on-line noble gas monitoring systems funded by the European Unit (EU) with masurement campaigns in Jakarta, Indonesia and Kuwait.
• Development and operation of stack monitoring system installed at the medical isotope production facility in Serpong, Indonesia.
