ABSTRACT

In the present work ayurvedic drug Tamra bhasma (TB) of different brands were procured, the pellets of different thickness of TB was prepared, by employing the non destructive technique, X-ray mass attenuation coefficients of Tamra bhasma have been measured using the variable energy X-ray source Am 241 as a source of characteristic X-rays of low energy (17.781, 22.581, 32.890 and 44.216 keV). These X-rays were used for interaction process with the sample (Tamra bhasma) and incident and transmitted photons are collected by a NaI(Tl) scintillation X-ray detector. The mass attenuation coefficients values are determined by following all procedure such as counting times, background intensities, error involved in counting statistics and good geometry is maintained for the counting of photon beams. The experimentally obtained values are compared with the theoretically calculated values, using the WinXcom data program. From obtained results, it reveals that, the variation in percentage deviation (PD) of experimental and theoretical calculated values of mass attenuation coefficient corresponds to the amount of bioenhancers, incorporated in Tamra bhasma during preparation process. Here variation in percentage deviation reflects drugs as the admixture of elements other than the pharmaceutical active ingredients (here in Tamra bhasma Cu is the Active Pharmaceutical Ingredient) which focuses on the purity and also change in quality of medicines.
