AbstractAbstract
[en] The first neutron radiography facility in Malaysia was constructed in 1984 and completed in 1985 at one of the radial beam ports of MINT TRIGA MARK II research reactor. The facility is known as NUR-2 and has been used as a basic R and D and inspection tool for archaeological and biological objects, aircraft and industrial components. However, this facility has low thermal neutron intensity at the sample position, which leads to long irradiation times; it gives many limitations for the industrial applications. The collimator used for this facility is based on step divergent collimator type. The best exposure technique established with this facility was a direct exposure technique, using a combination of Gadolinium (Gd) 25 μm converter and Kodak SR45 (SR5) film. The characteristics of the beam and image quality were studied by using a beam purity indicator (BPI) and sensitivity indicator (SI). The results obtained for image quality were quite good, and comparable with other facilities in the world, where all seven gaps and six holes were visible on the radiograph. A new neutron radiography facility called NUR-3 has been planned and designed, which will be set up at the Tangential Beam Port of RTP. In addition, the new facility will consist of a new collimator design, new imaging system using CCD camera. We present here some information on development of the MINT neutron radiography activities and the current status of the improvement. (author)
