21、1-09-17/19, Paris 2002-01-15/16, Paris 2002-03-26/27, Ringhals 2002-05-27/29, Paris 2002-10-14/15, Paris 2003-03-03/04, Paris 2003-06-16/17 and Paris 2003-12-08/09. This part of ISO 18589 has been prepared simultaneously with five other parts concerning the measurements of radioactivity in the soil

22、environment, and is complementary to the latter documents. ISO 18589 Parts 1 to 6 are addressed to those responsible for determining the radioactivity present in soils. This International Standard is published in several parts to be used jointly or separately according to needs. Parts 1 and 2 are ge

23、neral in nature. Parts 3 to 5 deal with nuclide-specific measurements, Part 6 with non-specific measurements of gross alpha or gross beta activities. Further parts may be added to this International Standard in the future if the standardization of measurements of other radionuclides becomes necessar

24、y. 1 Scope This part of ISO 18589 specifies the general requirements to carry out radionuclides tests on soil sample, including sampling. This part of ISO 18589 is addressed to people responsible for determining the radioactivity present in soils for the purpose of radiation protection. This may con

25、cern soils from gardens and 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 extent of the scope of testing activities. When a laboratory does not undertake one

26、 or more of the activities covered by this part of ISO 18589, such as planning, sampling or testing, the requirements of those clauses do not apply. This part of ISO 18589 is to be used in conjunction with other parts of ISO 18589 that outline the setting up of programmes and sampling techniques, me

27、thods of general processing of samples in the laboratory and also methods for measuring the radioactivity in soil. Its purpose is the following: define the main terms relating to soils, sampling, radioactivity and its measurement; describe the origins of the radioactivity in soils; define the main o

28、bjectives of the study of radioactivity in soil samples; present the principles of studies of soil radioactivity; identify the analytical and procedural requirements when measuring radioactivity in soil. This part of ISO 18589 is applicable if radionuclide measurements for the purpose of radiation p

29、rotection are to be made in the following cases: initial characterization of radioactivity in the environment; DIN ISO 18589-1:2009-02 7 routine surveillance of the impact of nuclear installations or of the evolution of the general territory; investigations of accident and incident situations; plann

30、ing and surveillance of remedial action; decommissioning of installations or clearance of materials. This part of ISO 18589 is not intended to cover scientific investigations of soil radioactivity and therefore does not apply to aspects of such measurements. 2 Normative references The following refe
