Independent evaluation of optically stimulated luminescence (OSL) 'dot' dosemeters for environmental monitoring.

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...
