| description | The Analytical Chemistry Laboratory at MINT is using the NAA technique since 1980s and is the only laboratory in Malaysia
equipped with a research reactor, namely the TRIGA MARK II. Throughout the years the development of NAA technique has been
very encouraging and was made applicable to a wide range of samples. At present, the k0 method has become the preferred
standardization method of NAA (k0-NAA) due to its multi-elemental analysis capability without using standards. Additionally, the k0
method describes NAA in physically and mathematically understandable definitions and is very suitable for computer evaluation.
Eventually, the k0-NAA method has been adopted by MINT in 2003, in collaboration with the Nuclear Research Institute (NRI),
Vietnam. The reactor neutron parameters (a and f) for the pneumatic transfer system and for the rotary rack at various locations, as well
as the detector efficiencies were determined. After calibration of the reactor and the detectors, the implemented k0 method was validated
by analyzing some certified reference materials (including IAEA Soil 7, NIST 1633a, NIST 1632c, NIST 1646a and IAEA 140/TM). The
analysis results of the CRMs showed an average u score well below the threshold value of 2 with a precision of better than 710% for
most of the elemental concentrations obtained, validating herewith the introduction of the k0-NAA method at the MINT. |
