The McLaughlin Centre is involved in
three major projects aimed at radiation risk assessment: the Residential
Radon and Risk of Lung Cancer- A Global Study consists
of the pooling of data from North American and European case-control
studies of residential radon and lung cancer; theInternational
Collaborative Study of Cancer Risk among Radiation Workers in the
Nuclear Industry that examines cancer incidences
and occupational radiation exposure; 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.
International Collaborative Study of Cancer Risk among
Radiation Workers in the Nuclear Industry
This study examines a cohort of over 600 000 nuclear industry workers
in seventeen countries initiated in 1990. The objective of the
study is to estimate the effect of low-dose protracted exposure
to ionizing radiation in order to improve radiation protection
standards for environmental and occupational exposures. A sub-cohort
of nuclear industry workers from the Canadian National Dose Registry
has been analyzed for mortality as Canada’s contribution
to the IARC study. Using the National Dose Registry of Canada,
scientists at the McLaughlin Centre are examining cancer incidence
and occupational radiation exposure in Canadian Nuclear Workers.
Residential Radon and Risk of Lung Cancer- A Global Study
In addition to being present at high concentrations in many types
of underground mines, radon is found in homes and is also present
outdoors. Extensive measurements of indoor radon concentrations
in homes show that although concentrations vary widely, radon
is universally present raising concerns that radon in homes increases
lung-cancer risk for the general population, especially those
who spend a majority of their time indoors at home. According
to the report “Biological Effects of Ionizing Radiation
(BEIR) VI Report: "The Health Effects of Exposure to Indoor
Radon" radon is the second leading cause of lung cancer
in the U.S. and that it is a serious public health problem. However,
the report acknowledges that there are gaps in our scientific
knowledge about the effects at low levels of radon exposure.
Since 1995, this project has been global in scope incorporating
European and North American studies. The McLaughlin Centre, led
by Daniel Krewski, will participate in the global pooling of
the North American data and European data for a global assessment
of the risks of residential radon exposure in the development
of lung cancer.
INTERPHONE
Potential health effects of electromagnetic fields (EMF) have been
a topic of scientific interest since the late 1900s, and have
received particular attention in the last 40 years. Common sources
of these fields include power lines, household electrical wiring,
appliances and motor driven instruments, computer screens, telecommunications
and broadcast facilities, cellular telephones and their base
stations. Cellular telephone use has increased steadily in the
past few years in many countries. In 1998, an international group
of scientists, from 13 countries including Canada, convened by
the International Agency for Research on Cancer (IARC) recommended
a coordinated international study of cancer risks related to
the use of cell phones. The Canadian study focuses around three
centres – Montreal, Ottawa and Vancouver/Victoria because
of the high prevalence of cell phone use over several years in
these cities. The McLaughlin Centre is coordinating, collecting
and analyzing the data from the Ottawa cohort of patients involved
in the study. |
