“…For elements leading to short-lived activation products the samples are each packed and sealed in 7 cm 3 rabbit capsules and sent for irradiation in turn in an outer irradiation channel B 4 where the neutron spectrum is "soft", the choice of the outer irradiation channel is to eliminate corrections, notably Mg in the presence of P. This is due to the proximity of the inner channels of MNSRs to the core leading to relative higher ratio of fast-to-thermal neutron 9 .…”

“…Under these conditions the reactor can operate with the same fuel loading for over ten (10) years with a burn up of <1%. Neutron flux parameter of MNSRs are known to be stable, thus permitting the use of semi absolute Neutron Activation Analysis (NAA) [5][6][7][8][9] . NAA in its instrumental form, has some unique features which makes it attractive to use for routing analysis.…”

Chrome tanned leather shavings collected from the federal college of chemical and leather technology (CHELTECH) Zaria, Nigeria's tannery were analyzed using centre for energy research and training (CERT), Zaria Nigeria's miniature neutron source reactor (MNSR). The main aim of this work was to determine the concentration of chromium and other constituents of the shavings. Chromium is known for its human toxicity which includes skin irritation, lung cancer, as well as Kidney, liver and gastric damages. The disposal of this waste without treatment will constitute a serious impact on the environment. The result obtained indicates that Chromium is as much as 1%. The analyzed concentrations of As, Ba, Br, Co, Fe, La, Na, Sb, Sc, Sm and Zn in the sample are also presented. The results obtained were validated with the data obtained from the analysis of certified reference materials, IAEA-336 (Lichen) and IAEA 359 (Cabbage).

“…Neutron Activation Analysis in its instrumental form (INAA), especially with research reactors, has some unique features, which makes it attractive to use for routine analysis. These are multielement capability, rapidity, reproducibility of results, complementary to other methods, freedom from analytical blank and independence of chemical state of elements (Jonah et al, 2006). These techniques can be used in qualitative as well as in quantitative analysis.…”

Laboratory study was carried out to determine some physicochemical properties and elemental composition of soil sample from Rijiyar determine its nutrient value and fertility. The elemental composition was determined using Neutron Activation Analysis (N.A.A.). After activation the sample was analyzed using a high efficiency high-purity germanium dete determined by employing gamma spectrometry. Mn, and Zn were obtained as 1.04±0.1%, 5±0.1%, 1.2±0.06%, 0.0749±0.0022%, 0.58±0.05%, 0.0004±0.00007%, 0.0139±0.000 below detection limit. The concentration of Al in the soil sample indicates that the soil is mineral, the low Na content implies it is non Cl -that indicated that the soil sample is neither saline nor purely acidic.

Soil serves as a major reservoir for contaminants as it posseses an ability to bind various chemicals together. To safeguard the members of the public from an unwanted exposure, studies were conducted on the sediments and soil from water bodies that form the major sources of domestic water supply in northern peninsular Malaysia for their trace element concentration levels. Neutron Activation Analysis, using Nigeria Research Reactor-1 (NIRR-1) located at the Centre for Energy Research and Training, Zaria, Nigeria was employed as the analytical tool. The elements identified in major quantities include Na, K, and Fe while As, Br, Cr, U, Th, Eu, Cs, Co, La, Sm, Yb, Sc, Zn, Rb, Ba, Lu, Hf, Ta, and Sb were also identified in trace quantities. Gamma spectroscopy was also employed to analyze some soil samples from the same area. The results indicated safe levels in terms of the radium equivalent activity, external hazard index as well as the mean external exposure dose rates from the soil. The overall screening of the domestic water sources with relatively high heavy metals concentration values in sediments and high activity concentration values in soil is strongly recommended as their accumulation overtime as a consequence of leaching into the water may be of health concern to the members of the public.
