Method of manufacturing a nanofluid and a system used in the manufacturing of the nanofluid

A system for use in the manufacture of a nanofluid, the system comprising:

• a frame having a first end wall defining;
• an opening through which a gamma ray emitter extends inwardly for emitting gamma rays along a beam path;
• a bridge fixed between opposite elongate side walls;
• a container for containing a mixture of a precursor of metallic nanoparticles and a base fluid;
• a gamma rays irradiator facing a side of the container for emitting gamma rays through the container;
• a second end wall which is arranged opposite to the first end wall, wherein the opposite side walls and the second end wall define an enclosure for shielding the environment surrounding the frame from the gamma rays;
• and
• a rotatable platform or turntable, fitted to the bridge, supporting the container such that the rotational axis of the container is arranged substantially perpendicular to the direction of travel of the gamma rays arranged to be emitted by the gamma rays irradiator, the rotatable platform being arranged to rotate the container during irradiation such that mixture held in the container is rotated relative to the gamma radiation beam rays thus substantially uniformly irradiating the mixture.
