The electronic equilibrium spectra created by cobalt-60 gamma-rays in some media (water, polystyrene, aluminum, iron, copper and lead) and in a LiF dosimeter placed in the media are calculated. The average electron mass attenuation coefficients and stopping powers are calculated over the spectra obtained. The Burlin general cavity theory is applied to obtain the response of LiF to cobalt-60 gamma-rays in the media considered using two different methods: considering the electron full spectrum or its maximum energy. Results are obtained using both methods for practical dimensions of LiF dosimeters and compared with experimental results from other authors. One can conclude that: considering the estimated upper limit (4%) of the relative error in the calculated ƒ values by both methods, these values agree in case of the first method (full spectrum) with the experimental results; in the second method (spectrum maximum energy), the existence of agreement depends on the expression used to define the electron attenuation coefficient as a function of the maximum energy.
