Marshall Islands
CDC received a request from the Republic of the Marshall
Islands to conduct an epidemiologic study of thyroid disease in the Marshall
Islands. If conducted, such a study would be the first at tempt to conduct a
nationwide assessment in the Marshall Islands of the relationship between
thyroid disease and radiation exposures from U.S. nuclear weapons tests in
the 1940s and 1950s. To date, a draft protocol for an epidemiologic study
has been developed. An important component of this proposed study is to
first determine the radiation doses to people who lived throughout the
atolls during the weapons testing period of the 1940s and 1950s.
Note: The proposed Marshall Islands
epidemiologic study would be the first nationwide evaluation of both thyroid
neoplasia and estimated radiation exposure from all nuclear weapons tests
conducted in the Marshall Islands.
Studies in the Former Soviet Union
CDC routinely provides technical assistance and expert
consultation to ongoing dose reconstruction and epidemiologic studies of the
effects of exposure to radionuclides released from nuclear facilities in the
former Soviet Union. CDC works with other U.S. and international agencies to
determine analytic studies of interest. CDC has also cooperated with the
International Atomic Energy Agency and other interested countries on
dose-reconstruction model-validation studies based on environmental data
collected in the aftermath of the Chernobyl event in 1986. The purpose of
this project is to use these data to evaluate the strengths and weaknesses
of various environmental transport and dosimetry models that may be useful
in dose reconstruction.
International Data Sets for Use in Testing
Environmental Transport Models
This collection includes
a number of environmental data sets that have become available through
environmental monitoring and dose reconstruction activities at various sites
throughout the world. The purpose of the collection is to assure the
long-term availability of high-quality data sets for use in development and
testing of environmental transport models, especially those used in dose
reconstruction activities. The present collection includes data sets
previously used in model validation exercises; several additional data sets
from the former Soviet Union that have not been previously used in test
exercises will be made available at a later date.
