ISO 51900:2009适用于进行辐射对食品和农产品影响研究所需的剂量测定的最低要求。此类研究包括建立这些产品的吸收剂量和相关效果之间的定量关系。ISO 51900:2009还描述了此类研究和结果报告中对剂量测定的总体要求。有必要将剂量测定视为实验的一个组成部分。 ISO 51900:2009适用于使用以下类型电离辐射进行的研究:伽马辐射、X射线（韧致辐射）和电子束。ISO 51900:2009的目的是确保选择辐射源和实验方法，使实验结果对其他科学家和监管机构有用和理解。 ISO 51900:2009描述了建立实验方法和常规实验的剂量测定要求；然而，ISO 51900:2009并不旨在限制实验者在确定实验方法时的灵活性。ISO 51900:2009包括注释形式的教程信息。 ISO 51900:2009不包括辐照设施安装鉴定或操作鉴定的剂量测定要求。

ISO 51900:2009 applies to the minimum requirements for dosimetry needed to conduct research on the effect of radiation on food and agricultural products. Such research includes establishment of the quantitative relationship between absorbed dose and the relevant effects in these products. ISO 51900:2009 also describes the overall requirement for dosimetry in such research, and in reporting of the results. It is necessary that dosimetry be considered as an integral part of the experiment. ISO 51900:2009 applies to research conducted using the following types of ionizing radiation: gamma radiation, X-ray (bremsstrahlung), and electron beams. The purpose of ISO 51900:2009 is to ensure that the radiation source and experimental methodology are chosen such that the results of the experiment will be useful and understandable to other scientists and regulatory agencies. ISO 51900:2009 describes dosimetry requirements for establishing the experimental method and for routine experiments; however, ISO 51900:2009 is not intended to limit the flexibility of the experimenter in the determination of the experimental methodology. ISO 51900:2009 includes tutorial information in the form of notes. ISO 51900:2009 does not include dosimetry requirements for installation qualification or operational qualification of the irradiation facility.
