Harmonizing chemical and radiation risk management

Article Abstract:

The necessity of resolving the discordance between the approaches of radiation and chemical risk management are discussed. This issue became evident when the EPA started to apply the same chemical risks criteria to radionuclides. A comparison of the particular framework for both issues was made to show the differences in regulatory choices for different situations. Several approaches that will enable the EPA and other regulatory agencies to adopt policies for the harmonization of these two frameworks are suggested.

Comment on 'Partide/Gas Concentrations and Distributions of PAHs in the atmosphere of Southern Chesapeake Bay'

Article Abstract:

The research of Gustafson and Dickhut on the particle/gas concentrations and distributions of polyaromatic hydrocarbons in the atmosphere of Southern Cheasapeake Bay failed to account for the potential effects of relative humidity on the slope of sorption coefficient and saturated vapor pressure. The research also erred in their conclusion stating that the slope should equal unity given that such deviations from unity are not uncommon even in the absence of artifacts.
