The Nuclear Analysis and Imaging Group has two major research areas: macroscopic material structure and composition research, with the following topics:

• Research in material sciences focuses mainly on porous materials (building materials).
• Monitoring real-time processes by dynamic imaging and PGAA, main focus: fuel cells, batteries, equipment using hydrogen-containing filling material.
• Biological research focuses on drought-tolerant plants.
• ⁵⁷Fe and ¹¹⁹Sn Mössbauer spectroscopy focusing on interdisciplinary materials research, including the study of various functional glasses, magnetic materials, minerals, and molecular systems, addressing scientific problems in both fundamental and applied research.
• ¹⁹⁷Au Mössbauer spectroscopy focusing on characterization of gold oxidation states and ligand environments in Au complexes.
•  Environmental safety studies byinvestigation of electrical and electronic waste for circular economy.
• Natural and artificial radioactivity assay by quantitative determination of the activity of radionuclides applying gamma spectroscopy.
• Computer simulation: MCNP and FISPACT case studies

The NAI Group utilizes the neutrons produced at the Budapest Research Reactor while operates five large-scale facilities of the BNC:

• Prompt Gamma Activation Analysis (PGAA)
• Neutron Induced Prompt-gamma Spectrometry (NIPS) station/facility.
• Neutron Optics and Radiography for Material Analysis (NORMA) station/facility
• Prompt Gamma Activation Imaging (PGAI), when NIPS and NORMA used jointly
• Neutron Activation Analysis (NAA) laboratory
• Neutron- and X-Ray-Radiography (RAD)  facility
• In-beam and conventional Mössbauer Spectroscopy (MS) measuring stations.

The NAI group has also complementary techniques like X-ray for nondestructive element analysis, imaging and macroscale structure analysis.

Besides the large-scale facilities the group operates and applies:

• two handheld X-ray fluorescence equipment (Delta Premium Innov-X/Olympus, and Bruker Tracer 5g/Bruker Handheld LLC.),
• a handheld Raman spectrometer with a microscope (BWTEK i-Raman Plus 785H, Raman Video Micro-Sampling System), and
• a 3D scanner (RANGEVision SMART 3D scanner).

NAI Group also deals with user measurements through excellence-based proposals.
