The radiological parameter mass attenuation and atomic cross section with biological material is essential in radiation dosimetry, medical therapy and radiobiology. Use of radioactive material such as; isotopes is increasing in the field of medical field specially in; diagnostics, research and development, bio-technology, pharmaceutical, agriculture etc. The attenuation parameters are the basic quantities required for determining the energy deposition and penetration in a given material. Here undecylic acid are play an essential role in human health society. So, this work focus on the absorption of gamma active radiation for fatty acid. The effect of gamma active radiations on absorption in undecylic acid are shown using attenuation parametrs which will be essential photon energy region of interest (500keV- 1500 keV) in many medical and biological applications. By performing transmission experiments using 137Cs, 54Mn, and 22Na gamma active sources with gamma ray spectrometry, The measured experimental data were compared against NIST-Xcom program and It has been found that the variations of observed values are decreasing with increasing photon energies.
