Coordinating office for medicinal products and their starting materials as well as commodities
- The radioecology laboratory measures the radioactive contamination in foods and environmental media, conducts field investigations and laboratory experiments and develops radiochemical methods for the quick determination of alpha and beta emitters in foods and environmental media.
- Scientific investigations and measurements are the foundation for understanding the fundamental processes responsible for the dispersal and the accumulation of radioactive substances in the environment and for describing them by radioecological models. They also help in making recommendations for the protection of the population when large amounts of radioactive substances are released into the environment.
- The radioecology laboratory is also the Coordinating Office for medicinal products and their starting materials and commodities.
Coordinating Office for pharmaceutical products and their starting materials and consumer goods
The aim of field investigations, laboratory experiments and method development is to
- determine the radioactive contamination of environmental media,
- understand the fundamental processes responsible for the dispersal and the accumulation of radioactive substances in the environment and to describe them by radioecological models,
- develop or optimize radiochemical methods for the determination of alpha and beta emitters in foods and environmental media,
- develop quick methods to be used in emergency preparedness or in cases of defense against nuclear hazards
- codify analytical methods in guidelines and procedure manuals.
Measurements: foundation for recommendations for the protection of the population
When large amounts of radioactive substances are released into the environment, for example after a nuclear power plant accident, the corresponding Land (federal state) authorities of the Länder (federal states) concerned, are mainly responsible for radioactivity measurements.
In addition, the radioactive contamination of environmental samples and foods samples is also measured in the radioecology laboratory of the Federal Office for Radiation Protection (BfS). The aim is to determine the radiological situation as quickly as possible.
Based on the data reported by the Länder and their own measurement results, BfS experts can make timely recommendations on effective measures for the protection of the population to political decision-makers.
Monitoring of the radioactive contamination after the Chernobyl reactor accident
The focus is especially on foods from the forest, such as mushrooms, which, even today, can still have increased contents of the radionuclide caesium-137.
Development of radiochemical methods
Another focus of the radioecology laboratory is the development and optimization of radiochemical methods for the determination of alpha and beta emitters in foods and environmental media. Here, quick methods used within the context of emergency preparedness or in cases of defense against nuclear hazards are of particular interest.
The radioecology laboratory is also the Coordinating Office for medical products and their starting materials and commodities. Within the scope of its function, for example teas, herbs and spices are randomly tested.
Among other things, the following is available for the preparation and radiochemical processing of the samples:
- mills and grinders,
- drying cabinets
- microwave digesters,
- refrigerated centrifuges as well as
- chemical fume hoods.
The instrumental equipment of the radioecology laboratory also includes high-purity germanium detectors as well as several measuring systems for the determination of alpha and beta emitters.
Quality assurance and quality management
As in all laboratories of the Federal Office for Radiation Protection a high value is placed on quality management and quality assurance.
The radioecology laboratory participates regularly in comparative measurements (interlaboratory comparisons and proficiency tests). Moreover, the radioecology laboratory is working towards accreditation according to DIN EN ISO/IEC 17025 (DAkkS (German accreditation body)) to prove its high-level technical and professional expertise.
The radioecology laboratory is a member of the international laboratory network ALMERA (Analytical Laboratories for the Measurement of Environmental Radioactivity) of the IAEA.
