![]() Validation of NAA Method for Urban Particulate Matter International Nuclear Information System (INIS) Woro Yatu Niken Syahfitri Muhayatun Diah Dwiana Lestiani Natalia Adventini Nuclear analytical techniques have been applied in many countries for determination of environmental pollutant. The analysis results are in agreement with the certified results in the scope of uncertainties and the f and α values at the irradiation site in the UZrH pulse reactor are 36.6 and 0.044 respectively. Using this system, three gamma-ray spectra for NAA of Au, Zr samples and GBW07107 rock standard sample have been analyzed. The analytical methods used in this system include absolute method, relative method and K 0 -method. The system has functions of radionuclide identification, f and α calculation, K 0 -value calculation, quantitative calculation of elemental concentrations, nuclides' data management, experiment design, computer simulation etc. An analytical software for NAA by using K0-method International Nuclear Information System (INIS) A Jingye Chen Da Tu Jing Chenweishi Zhang Wenshou Wang Daohua An analytical software has been designed for a personal computer in DOS environment to do reactor NAA by using K 0 -method. When the same sample was analyzed by ICP-AES, Al amounts in all the samples were 13% lower than those measured by NAA. To calibrate the fluorescence intensity from Allumogallion complex, Al amount in the cell was determined by NAA. The fluorescence intensity from the cell was increased rapidly between 4 and 8 hours of 1 mM Al treatment. The way how Al is taken up by tobacco cells through lumogallion staining method developed is presented. To study aluminum toxicity for plant, it is important to analyze the behavior of Al in cells. Al behavior in tobacco cells by NAA and staining method International Nuclear Information System (INIS) Iikura, H. Keywords: reactor parameter, Kartini reactor, k0-NAA, neutron flux 2. The value of f and α obtained can be used a database for the application of k0-NAA method for sample analysis in the laboratory NAA – CAST. The results of measurements for the f and α with the Cd-ratio method, providing more stable value than the triple bare method. Differences of measurement results obtained parameter values are significant in each channel irradiation, the value of Æ’ ranged from 13.713 to 22.128 and the value of α ranged from -0.060 – 0.068. The parameter value has been measured in three channels in the irradiation facilities Lazy Susan. The methods used include Cd-ratio and triple bare methods. ![]() In the application of k0-NAA method needed valuea of reactor parameters (f and α, then the purpose of the research would be conducted meaasurement parameter values f and α in the Lazy Susan Kartini reactor facilities. Kata kunci: parameter reaktor, reaktor Kartini, k0-NAA, fluks neutron  The k0-NAA method is an analysis method that widely used by many of the advantages. Nilai f dan α yang diperoleh dapat dijadikan basis data pada penerapan metode k0-NAA untuk analisis sampel di laboratorium AAN – PSTA. Hasil pengukuran f dan α dengan metode Cd-ratio, memberikan nilai yang lebih stabil dibandingkan metode triple bare. ![]() Diperoleh perbedaan hasil pengukuran nilai parameter yang signifikan pada setiap lubang iradiasi, nilai Æ’ berkisar 13,713 - 22,128 dan α berkisar -0,060 – 0,068. Telah diukur nilai parameter tersebut pada tiga lubang iradiasi di fasilitas Lazy Susan. Metode yang digunakan meliputi metode Cd-ratio dan triple bare. Dalam penerapan metode k0-NAA diperlukan nilai parameter reaktor (f dan α, maka tujuan penelitian ini adalah akan dilakukan pengukuran nilai parameter f dan α di fasilitas Lazy Susan reaktor Kartini. ANALISIS DAN PENGUKURAN PARAMETER REAKTOR KARTINI UNTUK PENERAPAN METODE K0-NAA Directory of Open Access Journals (Sweden) Sri Murniasih Full Text Available Metode k0-NAA merupakan metode analisis yang banyak digunakan dengan berbagai keunggulan.
