A shielded X-ray radiation apparatus is provided comprising an X-ray source, an X-ray attenuation shield including an elongate cavity to house the X-ray source and incorporating a region to accommodate a sample, a neutron attenuation shield, and a gamma attenuation shield. The neutron attenuation shield is situated adjacent to and substantially surrounds the X-ray attenuation shield and the gamma attenuation shield is adjacent to and substantially surrounds the neutron attenuation shield. In some embodiments a removable sample insertion means is provided to insert samples into the elongate cavity and which is composed of adjacent blocks of material, each respective block having a thickness and a composition which substantially matches the thickness and a composition of one of the X-ray attenuation, neutron attenuation and gamma-ray attenuation shields.

Disclosed is a method for building a nuclear reactor installation including a containment chamber surrounded by a protective casing. The method is characterised by the following essential construction phases: finding or preparing a cavern (2) in rocky ground or a mountain (3) which is connected to the outside world via a tunnel or shaft (4), constructing or introducing a sealed protective casing (5) made of steel which delimits the containment chamber (1) forming an enveloping intermediate chamber volume (6) between the protective casing (5) and the cavern walls (2′), and, filling the intermediate chamber (6) with concrete or cement (6′), with the exception of the tunnel or shaft (4).
