Metrologia das Radiações Ionizantes na Saúde e Indústria

Objectives

To acquire knowledge on ionizing radiation metrology related to: dosimetry (health sector) and radionuclides (industrial sector). Regarding the health sector, to understand the fundamentals of the most relevant primary standards. In what regards the industrial sector, to understand the basic principals for the detection of radioactivity and for the measurement of radionuclides activity. To understand the metrological pyramid, the concept of traceability and the different approachs for uncertainty calculation. The metrology from the institutional point of view.
