pollutants,   etc   ; humans; regression analysis;     Show all 3 Subjects
Abstract:
... The concentrations of a pollutant in people or in the environment are often changing as a function of time. In many cases, this rate of change may be relatively constant as a function of time; thus, first-order kinetics can be applied to these data. In other cases, the rate at which the concentrations of a pollutant are changing may be different before and after some event, for example before and ...

Abstract:
... Radiological atmospheric releases require population dose calculation for proper determination of preventive measures. The old concept of relative concentrations requires long lasting constant emission which is not realistic.The proposed concept of the “relative doses” is the generalization and expansion of the known concept of relative concentrations. Relative doses allow an evaluation of the gen ...
