[[Radiation monitoring]] involves the measurement of radiation dose or radionuclide contamination for reasons related to the assessment or control of exposure to radiation or radioactive substances, and the interpretation of the results. The methodological and technical details of the design and operation of environmental radiation monitoring programmes and systems for different radionuclides, environmental media and types of facility are given in IAEA Safety Standards Series No. RS–G-1.8 <ref>{{cite book |title=Environmental and Source Monitoring for Purposes of Radiation Protection, IAEA Safety Standards Series No. RS–G-1.8 |last1=International Atomic Energy Agency |authorlink= |year=2005 |publisher=IAEA |location=Vienna |isbn= |pages= |url=http://www-pub.iaea.org/MTCD/publications/PDF/Pub1216_web.pdf |accessdate=}}</ref> and in IAEA Safety Reports Series No. 64.<ref>{{cite book |title= Programmes and Systems for Source and Environmental Radiation Monitoring.

==MeasurementUkuran==
Pencemaran radioaktif mungkin wujud di permukaan atau dalam isipadu bahan atau udara. Dalam logi kuasa nuklear, pengesanan dan pengukuran sering kali merupakan tugas utama Ahli Fizik Kesihatan yang Disahkan.
Radioactive contamination may exist on surfaces or in volumes of material or air. In a [[nuclear power plant]], detection and measurement of radioactivity and contamination is often the job of a [[Certified Health Physicist]].
