Scientific data on natural occurring radioactive materials (NORMs) is available in unknown quantities and the data is fragmented over several different sources. The new EU-BSS is regulating the use of NORM in building materials, however a large scale database with country specific information that can support legislators and industry in the assessment of the radiological impact of the use of by-products in construction is missing. Currently the COST Action ‘NORM4BUILDING’ (2014–2017) is creating such a database using a semi-automated datamining approach. In this paper radiological aspects on by-products that can find application in concrete are discussed based on the database.

有关天然放射性物质（NORM）的科学数据数量未知，并且数据分散在几个不同的来源上。新的欧盟BSS正在规范建筑材料中NORM的使用，但是缺少一个具有国家特定信息的大型数据库，该数据库可以支持立法者和行业评估建筑中使用副产品的放射学影响。目前，COST行动“ NORM4BUILDING”（2014-2017年）正在使用半自动数据挖掘方法来创建这样的数据库。在本文中，基于数据库讨论了可以在混凝土中找到应用的副产物的放射学方面。
