ISO 27048:2011规定了职业暴露于放射性物质内部污染风险的工人监测数据评估的最低要求。它提出了监测数据标准化解释的程序和假设，以达到可接受的可靠性水平。这些程序允许对暴露进行量化，以记录是否符合法规和辐射防护计划。在剂量水平方面，为程序的适用性设定了限值，超过该限值，必须采用更复杂的方法。 ISO 27048:2011阐述了以下内容:基于常规和特殊监测计划参考水平的剂量评估程序；选择剂量临界参数值的假设；确定监测结果重要性的标准； 解释工作场所监测结果；取样、测量技术和工作条件引起的不确定性；专题:解释不同时间不同测量方法产生的多个数据，处理低于决策阈值的数据，恶意数据，以及计算胚胎/胎儿和婴儿的剂量；报告/文件；质量保证 它不适用于以下情况:诉讼案件的剂量测定；改进内部剂量学的建模；非公司化措施的潜在影响（例如使用螯合剂）；调查接触的原因或影响；污染伤口的剂量测定。

ISO 27048:2011 specifies the minimum requirements for the evaluation of data from the monitoring of workers occupationally exposed to the risk of internal contamination by radioactive substances. It presents procedures and assumptions for the standardised interpretation of monitoring data, in order to achieve acceptable levels of reliability. Those procedures allow the quantification of exposures for the documentation of compliance with regulations and radiation protection programmes. Limits are set for the applicability of the procedures in respect of the dose levels above which more sophisticated methods will have to be applied. ISO 27048:2011 addresses the following: procedures for dose assessment based on reference levels for routine and special monitoring programmes; assumptions for the selection of dose-critical parameter values; criteria for determining the significance of monitoring results; interpretation of workplace monitoring results; uncertainties arising from sampling, measurement techniques and working conditions; the special topics of interpretation of multiple data arising from different measurement methods at different times, handling data below the decision threshold, rogue data, and calculation of doses to the embryo/foetus and infant; reporting/documentation; quality assurance. It is not applicable to the following: dosimetry for litigation cases; modelling for the improvement of internal dosimetry; the potential influence of decorporation measures (e.g. administration of chelating agents); the investigation of the causes or implications of an exposure; dosimetry for contaminated wounds.
