There are four (4)  four  main sections under NAC which include the Non-destructive  Testing  (NDT) , Radioisotope  based  Technology  (RBT),  the Solid-State Nuclear Track Detection (SSNTD)  and the X-ray Fluorescence(XRF) Spectrometry sections.

The NDT and the radioisotope based technology (RBT) sections both offer non destructive evaluation services (NDES).NDES provides consultancy and inspection services for some types of engineering materials, components, assemblies and installations. NDES also provides a number of non-destructive examination services which includes trouble shoot problems in industrial process plants and certification of welders which can be undertaken in-house or at remote locations.

Some of the services provided by the NDT include Radiographic Testing (RT), Ultrasonic Testing (UT), Magnetic Particle Inspection (MPI) and Penetrant Testing (PT).

In RBT, process anomalies such as channelling and stagnancy are diagnosed with unsealed sources (radiotracers) using residence time distribution (RTD) techniques. Distillation columns are gamma scanned to locate collapsed trays, blockages, flooding and other process upsets.

The SSNTD laboratory is involved in mapping out levels of Radon-222 concentrations to determine the risk due to radon exposure, map out radon prone areas in Ghana and determine the fault lines associated with earthquake. This will be used to seek legislative backing from Environmental Protection Agency (EPA) on the control of hazards due to radon gas emissions.

XRF laboratory at NAC is involved in elemental analysis and simulations. It is engaged in  air monitoring of total suspended particles(TSP) and Particulate matter size 10(PM10), noise levels, black carbon analysis, nitrogen oxides(NOx) and sulphur oxide (SOx). XRF staff carry out environmental impact assessment for quarries, mines and industries.
