Measurement of mass attenuation coefficient and its photon interaction derivables in some skeletal muscle relaxants

We have measured the mass attenuation of some commonly used skeletal muscle relaxants such as tubocurarine chloride, gallamine triethiodide, pancuronium bromide, suxamethonium bromide and mephenesin for various gamma sources of energy ranging from 84 keV to 1330 keV (¹⁷⁰Tm, ⁵⁷Co, ¹⁴¹Ce, ²⁰³Hg, ⁵¹Cr, ¹¹³Sn, ²²Na,¹³⁷Cs, ⁶⁰Co,²²Na and ⁶⁰Co). The measured values agree with the theoretical values. The effective atomic numbers (Z_eff) and electron density (N_e) of commonly used skeletal muscle relaxants for total and coherent, incoherent, photoelectric absorption, pair production in atomic and nuclear field photon interaction have been computed in the wide region 1 keV to 100 GeV using an accurate database of photon-interaction cross sections and the WinXCom program
