21/30441990 DC

This standard 21/30441990 DC BS ISO 18589-2. Measurement of radioactivity in the environment. Soil is classified in these ICS categories:

• 13.080.01 Soil quality and pedology in general
• 17.240 Radiation measurements

This document 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 rock from bedrock and ore, construction materials and products, potery, etc. using NORM or those from technological processes involving Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM) e.g. the mining and processing of mineral sands or phosphate fertilizer production and use, as well as of sludge and sediment.

For simplification, the term “soil” used in this document covers the set of elements mentioned above.

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.

This document is applicable to all laboratories regardless of the number of personnel or the range of the testing performed. When a laboratory does not undertake one or more of the activities covered by this document, such as planning, sampling, or testing, the corresponding requirements do not apply.
