Alpha particles have been used for the first time in order to characterize the transport properties of polycrystalline CVD diamond films. Advantages with respect to other techniques which make use of alpha particles or light are that it is easier to discriminate between holes and electrons, localization of deposited energy is more precise and the value of deposited energy is not subjected to Landau fluctuations
