US 11,029,428 B1 · Radiological criticality dosimeter using nanoparticle technology in additive manufacturing

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.

Dependent claims

A nuclear criticality dosimeter, comprising:

a first neutron detection composition comprising gold nanoparticles dispersed through a polymer selected from the group consisting of acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), polyamide (PA), polycarbonate (PC), and combinations thereof, and
a second neutron detection composition comprising sulfur nanoparticles dispersed through a polymer selected from the group consisting of ABS, PLA, PA, PC, and combinations thereof,
where the nanoparticles in the first and second neutron detection compositions are activated by neutron radiation exposure during a nuclear criticality, and emit radiation corresponding to the neutron radiation exposure.
