Measurement of radioactivity in the environment - Soil - Part 7: In situ measurement of gamma-emitting radionuclides (ISO 18589-7:2013)
ISO 18589-7:2013 specifies the identification of radionuclides and the measurement of their activity in soil using in situ gamma spectrometry with portable systems equipped with germanium or scintillation detectors.
ISO 18589-7:2013 is suitable to rapidly assess the activity of artificial and natural radionuclides deposited on or present in soil layers of large areas of a site under investigation.
ISO 18589-7:2013 can be used in connection with radionuclide measurements of soil samples in the laboratory (ISO 18589‑3) in the following cases:
· routine surveillance of the impact of radioactivity released from nuclear installations or of the evolution of radioactivity in the region;
· investigations of accident and incident situations;
· planning and surveillance of remedial action;
· decommissioning of installations or the clearance of materials.
It can also be used for the identification of airborne artificial radionuclides, when assessing the exposure levels inside buildings or during waste disposal operations.
Following a nuclear accident, in situ gamma spectrometry is a powerful method for rapid evaluation of the gamma activity deposited onto the soil surface as well as the surficial contamination of flat objects.

Mesurage de la radioactivité dans l'environnement - Sol - Partie 7: Mesurage in situ des radionucléides émetteurs gamma (ISO 18589-7:2013)
L'ISO 18589-7:2013 spécifie l'identification des radionucléides et la quantification de leur activité dans le sol en utilisant la spectrométrie gamma in situ avec des systèmes portatifs équipés de détecteurs au germanium ou à scintillations.
L'ISO 18589-7:2013 est adaptée pour évaluer rapidement l'activité des radionucléides artificiels et naturels déposés ou présents dans des couches du sol d'un site soumis à l'étude.
L'ISO 18589-7:2013 peut être utilisée en relation avec les mesurages de radionucléides des échantillons de sol au laboratoire [ISO 18589‑3] dans les cas suivants pour
la surveillance en routine de l'impact de la radioactivité émanant d'installations nucléaires ou de l'évolution de la radioactivité du territoire,
les investigations en situations d'accidents et d'incidents,
la planification et la surveillance des actions de remédiation, et
le déclassement d'installations ou l'élimination de matières nucléaires.
L'ISO 18589-7:2013 peut également être utilisée pour identifier les radionucléides artificiels dans l'air, lors de l'évaluation des niveaux d'exposition à l'intérieur de bâtiments ou au cours des opérations d'élimination de déchets.
Merjenje radioaktivnosti v okolju - Tla - 7. del: Meritve radionuklidov, ki sevajo žarke gama, na kraju samem (ISO 18589-7:2013)
Standard ISO 18589-7:2013 določa identifikacijo radionuklidov in merjenje njihove aktivnosti v zemljini z gama spektrometrijo na kraju samem s prenosnimi sistemi, opremljenimi z germanijevimi ali scintilacijskimi detektorji.
