Electron emission during the fracture of a rock subjected to uniaxial compression has been detected with a G-M counter and a plastic scintillation counter. The energies of the electrons detected by the two counters are estimated to be greater than 0.05 MeV and 0.35 MeV, respectively. Based on this result, a mechanism for the emission of light and other electromagnetic radiations observed during rock fracture is suggested.
