This is characteristic of beta decay. In beta decay, a neutron is transformed into a proton, creating an electron and an antineutrino. The electron is emitted from the nucleus, and this is what causes the amount of undecayed sample to decrease. After two hours, roughly one-eighth of the sample will remain undecayed.
