Relative implications of protective responses versus damage induction at low dose and low-dose-rate exposures, using the microdose approach.

abstract：:The substantive safety of radiological and other medical procedures can be radically reduced by unconscious factors governing scientific thought. In addition, the historical exclusion of women from these disciplines has possibly skewed their development in directions that now need to be addressed. This paper focuses o...
