Environmental Risk Assessment at a Gas Utility
Over the past 10 years, Southern California Gas Company (SoCalGas) has developed an environmental risk management program to mitigate or eliminate the potential health risks to employees,...
Monte Carlo Simulations of Uncertainties in Risk Assessments of Superfund Sites Using Crystal Ball?
Most health risk assessments for Superfund sites combine a series of worst case assumptions to derive a 'point estimate' of risk that is 'conservative,'...
Occupational and Environmental Exposures to Radon: A Perspective for Mitigators
Occupational exposures to radon and radon decay products and the associated high incidence of radiation induced lung cancer form the basis for our present-day concern for limiting exposures...
Technical Issues Related to Emission Releases from Subslab Radon Mitigation Systems
Surveys of government and private sector radon mitigation activities indicate that subslab radon mitigation systems account for more than 50 percent of all installed systems. Such systems...
