TL;DR: The attenuation of gamma rays in some fatty acids, viz formic acid (CH 2 O 2 ), acetic acid (C 2 H 4 O 2), propionic acid, butyric acid, n -hexanoic acid, lauric acid and myristic acid have been measured at the photon energies 81, 356, 511, 662, 1173 and 1332,keV Experimental values for the molar extinction coefficient, effective atomic number and the electron density have been derived and compared with theoretical calculations as discussed by the authors.

TL;DR: In this paper, the current state of knowledge of experimental and theoretical gamma-ray and X-ray attenuation coefficients in aqueous solutions of salts is presented and exemplified by recent work.
Abstract: Accurate values of X-ray and gamma-ray attenuation coefficients of different chemicals are required in spectrometry as well as in many other scientific, engineering and medical disciplines involving photon radiation. The current state of knowledge of experimental and theoretical gamma-ray and X-ray attenuation coefficients in aqueous solutions of salts is presented and exemplified by recent work. The results presented provide a basis for studying X-ray and gamma-ray photon interactions with ions in solution (hydrated ions) rather than ion compounds in solid form.
