Abstract

Compositions including additive manufacturing materials incorporating radiological detection materials therein are provided. Also provided are apparatus and methods, which may be utilized to monitor and measure nuclear criticality events, and determine if personnel have been exposed to ionizing radiation. The compositions, apparatus, and methods beneficially improve accuracy in assessing radiation exposure, particularly neutron exposure, and reduce degradation of the radiological detection materials.
