ESTIMATIVA DE DOSE ABSORVIDA PELO PACIENTE RELACIONADA À ANATOMIA IRRADIADA
Brazilian Journal of Radiation Sciences, 2016 Desenvolveu-se uma equação direta para estimar a dose absorvida pelo paciente em exames radiográficos, utilizando parâmetros elétricos, geométricos e de filtragem combinados com dados da anatomia irradiada. Para determinar a dose absorvida em cada exame,

A generalized definition of dosimetric quantities [PDF]
, 1990 The current definitions of microdosimetric and dosimetric quantities use the notion of 'ionizing radiation'. However, this notion is not rigorously defined, and its definition would require the somewhat arbitrary choice of specified energy cut-off values
