DIN EN ISO 18589-2:2024-12

This standard specifies the general requirements, based on ISO 11074 and ISO/IEC 17025, for all steps in the planning (desk study and area reconnaissance) of the sampling and the preparation of samples for testing. It includes the selection of the sampling strategy, the outline of the sampling plan, the presentation of general sampling methods and equipment, as well as the methodology of the pre-treatment of samples adapted to the measurements of the activity of radionuclides in soil including granular materials of mineral origin which contain NORM or artificial radionuclides, such as sludge, sediment, construction debris, solid waste of different type and materials from technologically enhanced naturally occurring radioactive materials (mining, coal combustion, phosphate fertilizer production etcetera). This document is addressed to the people responsible for determining the radioactivity present in soil for the purpose of radiation protection. It is applicable to soil from gardens, farmland, urban, or industrial sites, as well as soil not affected by human activities. The main objectives of the measurement of radionuclides in soil are the following: - characterization of radioactivity in the environment; - routine surveillance of the impact of radioactivity released from nuclear installations or of the general evolution of the radioactivity in a region; - investigations of accidents and incidents; - planning and surveillance of remedial action; - decommissioning of installations or the disposal of materials.
