Daniel Krewski Projects

Radiation Risk Assessment
The widespread use of wireless telecommunications devices, particularly cellular telephones, has resulted in increased human exposure to radiofrequency fields (RF) also referred to as non-ionization radiation. Occupationally exposed populations to ionizing radiation and individuals exposed to residential radon coming from the soil are also groups at-risk for adverse health outcomes, including cancer. Dr. Krewski is involved with three major projects aimed at radiation risk assessment: the Combined Analysis of North American Case-Control Studies of Residential Radon and Lung Cancer; the National Dose Registry of Canada which will assess the cancer risks associated with occupational ionization radiation of Canadian Nuclear Workers; and the INTERPHONE study, an international collaborative case-control study investigating whether cellular telephone use is associated with an increase risk of tumours of the brain and salivary glands.

Air Pollution
Hazardous chemicals released by such agents as exhaust from cars, industrial plants and homes have been shown to contribute to negative health outcomes such as asthma, stroke, and heart attack. The concentration and composition of air pollution varies between urban centers and rural areas and between regions and climates, making national and international analysis of air pollution necessary for better risk management decisions. The McLaughlin Centre is active in the NERAM Colloquia Series on Air Pollution Health Effects. This is a series of conferences aimed at advancing research in evidence-based policy analysis to guide air quality objectives, standard setting, clean air implementation plans and urban planning decisions.

Prion Diseases
In recent years, Canada along with many other countries has faced a growing number of crises related to the safety of agricultural products including mad cow disease (BSE). Recent scientific analysis has linked eating infected beef with the disease variant CJD, which is incurable and therefore the need to prevent mad cow disease has become an important health issue. As part of the PrioNet Network, Dr. Krewski is developing a conceptual integrated risk management framework; extending models projecting risks of prion disease to include more current information, which is both population and laboratory based, to achieve more accurate estimates of risk; and applying our risk management framework to the analysis of BSE risks in Canada, using the new information developed in this project.

Radon
In an effort to reduce the rate of lung cancer around the world, the World Health Organization (WHO) launched the International Radon Project to help countries reduce the health risks associated with radon gas. The goal of the project is to identify effective strategies for reducing the health impact of radon, promoting sound policy options for countries and increasing public and political awareness about the consequences of exposure to radon.

In addition, in order to communicate the nature of residential radon as a population health risk to the Canadian public, Dr. Krewksi developed a Radon Handbook for Canada with funding from Health Canada. Information: Dr. Daniel Krewski
