A look inside
Nondestructive investigation of metal objects with neutron tomography and gamma spectroscopy
This is a NWO-NICAS project. This project integrates technical research on sculpture and archaeological metal objects at the Rijksmuseum with neutron-based analyses at the TU Delft Reactor Institute, in order to characterize interior structures, composition and condition.
About the project
Cooperating with scientists at the Reactor Institute at TU Delft, we are developing new neutron-based examination techniques to gather information that cannot be obtained through more traditional methods of technical study such as x-radiography. Neutrons and gamma-rays penetrate metals easily and are capable of generating quantitative information throughout the entire bulk of a statue non-destructively. By developing algorithms to fuse data from neutron and gamma-ray tomography, we aim to quantify the elements present in the alloy and corrosion, and to reveal structures hidden in the interior of metal objects.
Aim of the project
The goal of the project is to fully exploit the non-destructive technique of neutron tomography by fusing the data with those from gamma spectroscopy, in order to ascertain the structure and composition of the object (alloy composition, corrosion, crystal structure, core material). At the same time, we will establish a protocol for the use of neutron-based methods for cultural heritage objects and demonstrate their safety and effectiveness.

Beeldvorming is a project funded by NWO from a budget earmarked for NICAS (Netherlands Institute for Conservation+Art+Science+).
For this project we work together with the TU Delft, the University of Amsterdam and the RCE.
