Large-scale using of ionizing radiation for medical investigations has benefits and risks. Every country has national standards for radiation protection, defining responsibilities of individuals and organizations for radiation control. In spite of the rich legislation, the total cumulated dose absorbed by a patient during medical investigations is not cumulated or established in a unified manne...

Thermoelectric phenomena in photoexcited graphene have been the topic of several theoretical and experimental studies because their potential usefulness optoelectronic applications. However, available descriptions thermoelectric effect terms Seebeck coefficient do not take into account role electron density. In this work, we adopt concept effective [G.D. Mahan, J. Appl. Phys. 87, 7326 (2000)] e...
