Neoplastic transformation of a human hybrid cell line by alpha particles in relation to mammography X rays.

abstract：:There is a preoccupation with linearity and absorbed dose as the basic quantifiers of radiation hazard. An alternative is the fluence approach, whereby radiation hazard may be evaluated, at least in principle, via an appropriate action cross section. In order to compare these approaches, it may be useful to discuss th...
