ISO 1

34、8589-1 to ISO 18589-6 concerning the measurements of radioactivity in the soil, have been prepared simultaneously. These parts are complementary and are addressed to those responsible for determining the radioactivity present in soils. The first two parts are general in nature. ISO 18589-3 to ISO 18

35、589-5 deal with radionuclide-specific measurements and ISO 18589-6 deals with non-specific measurements of gross alpha or gross beta activities. ISO 18589-7 deals with the measurement of gamma emitters radionuclides using in situ spectrometry.Additional parts can be added to ISO 18589 in the future

37、art of ISO 18589 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 pl

38、an, 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.This part of ISO 18589 is addressed to the people responsible for determining the radioactivity present in s

39、oil 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.This part of ISO 18589 is applicable to all laboratories regardless of the number of personnel or the range of the testing perfor

45、 population.2,3,4,5The main objectives of the measurement of radionuclides in soil (see ISO 18589-1) 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 rad

46、ioactivity in a region; investigations of accidents and incidents; planning and surveillance of remedial action; decommissioning of installations or the disposal of materials.Consequently, measurements of soil radioactivity are performed in a variety of situations, but a generic approach can be desc

The sampling strategy shall lead to the knowl
