“…The finding of toxic and trace constituents in cigarette tobacco is important both from the perspective of health studies connected with smoking and, more generally, aspects of the uptake of trace elements by plants. The results for the Egyptian tobacco (Table 2) were compared with analyses of Turkish [19], Iranian [20], Mexican [21] and Brazilian tobacco [22]. Table 4 compares the results of studies of trace element contents of cigarettes in various countries.…”

The Instrumental Neutron Activation Analysis (INAA) technique was used to analyse 10 cigarette brands sold in the Egyptian market. The concentrations of trace and major constituents were measured to better understand the hazardous effects of smoking Egyptian cigarette tobacco. The samples were irradiated at the core of the Second Research Egyptian Reactor ET-RR-2, and the induced activities were counted by -ray spectrometry using an efficiency-calibrated High Purity Germanium (HPGe) detector. The NAA k0-standardization method was used to determine the concentrations of 14 elements (Ba,

“…The contribution of the cigarette~paper elements to smoke is extremely difficult to evaluate because the elements found to be present in the paper all exist in higher concentrations in the tobacco, and the contribution of the paper cannot be tested directly by insuu~ mental neutron-activation analysis. Calcium is one ele~ ment in cigarette paper (usually as a whitening agent) whose contribution to smoke has been studied by jEN~ KINS et al (107) and AHMAD (105), ABEOINZADEH et al (102) determined 20 elements in the paper of an Iranian cigarette and they noted only a small, if any, contribu~ cion of these elements to the total-mass concentration in the smoke. Some laboratories, in an attempt to correlate the transfer rate of inorganic components to smoke, have analyzed the cigarette ash.…”

In summary, nuclear radiation has been widely used to elucidate many aspects of the mechanisms of tobacco being converted to smoke. In addition, the mechanisms of smoke transfer, tobacco inorganic chemistry and smoke filtration have been clarified by many authors worldwide. The newer techniques now being developed, using radiation detection coupled with the enhanced use of electronic-data reduction and interpretation, promise to continue the important role these techniques have played in understanding smoke-formation mechanisms.

Nowadays, there are many elemental analysis methods that use chemical, physical and nuclear characteristics. However, a particular method may be favoured for a specific task, depending on the purpose. Neutron activation analysis (NAA) is very useful as sensitive analytical technique for performing both qualitative and quantitative multielemental analysis of major, minor and traces components in variety of terrestrial samples and extra-terrestrial materials. In addition, because of its accuracy and reliability, NAA is generally recognized as the "referee method" of choice when new procedures are being developed or when other methods yield results that do not agree. It is usually used as an important reference for other analysis methods. Worldwide application of NAA is so widespread it is estimated that approximately 100,000 samples undergo analysis each year. The method is based on conversion of stable atomic nuclei into radioactive nuclei by irradiation with neutrons and subsequent detection of the radiation emitted by the radioactive nuclei and its identification. The basic essentials required to carry out an analysis of samples by NAA are a source of neutrons, instrumentation suitable for detecting gamma rays, and a detailed knowledge of the reactions that occur when neutrons interact with target nuclei. Brief descriptions of the NAA method, reactor neutron sources, and gammaray detection are given below.
