The production of aluminum nanoparticles and the determination of the size of these nanoparticles by safe and low-cost radiography through the design and construction of electrical explosion of wire and X-ray radiography equipment are among the objectives of this research. Using a wire explosion device, currents of 20, 115, and 250A were applied to the aluminum wire, and based on the results obtained, nanoparticles with dimensions of 20 to 100 nanometers were obtained. The current and electric arc force used affect the amount of aluminum nanoparticles dispersed in the solution, the clarity and width of the laser light path, and the color of the solution. For the minimum amount of current and force, the concentration of nanoparticles in the solution is lower and its color is clearer, and the width of the laser light has its lowest value. Also, for the maximum amount of current and force, the amount and concentration of nanoparticles dispersed in the solution increases and the solution has a darker color. In this case, the laser light path is clearer and its width is also the highest. The designed radiography device is equipped with an X-ray tube housing to eliminate lead contamination in the X-ray room and increase safety. Through nano-radiography, using X-ray radiation to the produced nanoparticles and considering the waves emitted from the nanoparticles and the colors observed in the radiography, the dimensions of the aluminum nanoparticles were determined and compared with the results obtained for copper nanoparticles.
