In this work, we studied $^{13}$C($\\alpha,n)^{16}$O reactions induced by $\\alpha$-particles emitted within the calibration sources of the \\textsc{Majorana Demonstrator}. These sources are thorium-based calibration standards enclosed in carbon-rich materials. The reaction rate was estimated by using the 6129-keV $\\gamma$-rays emitted from the excited $^{16}$O states that are populated when the incoming $\\alpha$-particles exceed the reaction Q-value.
