The quenching of photoluminescence in InAs/GaAs quantum dots and quantum wells by 2 MeV electron irradiation is investigated. We demonstrate a much higher radiation hardness of the quantum dots. Possible mechanisms of this phenomenon are discussed in terms of the wavefunction localization and defect reactions.
