Sample interview questions: Can you explain the concept of nuclear forensics and its role in security and law enforcement?
Sample answer:
Nuclear forensics is the application of nuclear science and technology to investigate and attribute the source of nuclear materials involved in illicit activities, such as nuclear proliferation or nuclear terrorism. It plays a crucial role in security and law enforcement by providing valuable information to identify the origin and intended use of nuclear materials, assisting in the attribution of responsibility, and deterring future illicit activities.
Nuclear forensics involves a range of techniques and methodologies, including:
- Radioactive Isotope Analysis: Identifying the specific isotopes present in the nuclear material and determining their ratios can provide insights into the material’s source and processing history.
- Trace Element Analysis: Identifying and measuring trace elements in the nuclear material can help establish its origin and identify any potential links to specific nuclear facilities or geographic locations.
- Particle Accelerator Mass Spectrometry (PAMS): This technique allows for ultra-sensitive detection and quantification of specific isotopes, providing valuable information about the material’s age and source.
- Neutron Activation Analysis (NAA): Irradiating the nuclear material with neutrons activates specific isotopes, which can then be identified and quantified to provide information about the material’s composition and origin. Read full answer
