This report has as an objective to assess the activation problem of the thorium target irradiation experiment at FNAL. The results presented are not activation calculation per se, but they provide guidelines to assess any possible impact on the beam stop surroundings due to the irradiation of the target with the low pulse rate 8 GeV proton beam. The average beam intensity is assumed to be 1.32 x10 11 protons per second and a full week of irradiation is assumed.
