Welcome to the ILIAS database on radiopurity of materials

This site is part of the ILIAS program, a common European project for the development of the underground science.
Data sources: UKDM Collaboration (Boulby Mine), ANAIS, CAST, ROSEBUD Collaborations (Canfranc Underground Laboratory), EDELWEISS (Laboratoire Souterrain de Modane), BOREXINO (Gran Sasso)


The database provides access to radionuclide concentration in materials commonly used in low background experimental set-ups. The measurements have been performed by groups involved in experiments which require extremely low backgrounds.


While this data is an useful guide for material selection, the radionuclide concentration may vary depending on the lot. Therefore, it is necessary to control all used materials when building low background set-ups.
