US 11,456,147 B2 · Shielded X-ray radiation apparatus

Abstract

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.

Dependent claims

A shielded X-ray radiation apparatus for analysis of materials via gamma activation analysis, the apparatus comprising:

an X-ray conversion target, wherein, when an electron accelerator directs an electron beam having an electron beam direction at the X-ray conversion target, the X-ray conversion target generates X-rays;
an X-ray attenuation shield including an elongate cavity to house the X-ray conversion target and incorporating a region to accommodate a sample;
a neutron attenuation shield;
a gamma attenuation shield;
and
a support casing housed within the X-ray attenuation shield and configured to support the X-ray conversion target and the sample,
wherein the neutron attenuation shield is adjacent to and substantially surrounds the X-ray attenuation shield;
and
wherein the gamma attenuation shield is adjacent to and substantially surrounds the neutron attenuation shield.
