Discovering the causes of cancer and the means of prevention

Environmental Radiation Exposures

DCEG is investigating cancer risks among populations exposed to radiation from environmental sources, such as nuclear reactor accidents and fallout from weapons testing.  

Atomic Bomb Survivors
Studies of atomic bomb survivors in Hiroshima and Nagasaki, including updates to cancer incidence, radiation dose risk assessment, and molecular genetics studies.

Childhood Leukemia and Background Radiation
A record linkage study designed to investigate the association of childhood leukemia with natural background radiation exposure.

Radiation Dosimetry Research to Support Epidemiological Studies
DCEG dosimetry researchers are developing methods for more accurate dose estimates and for reducing uncertainty in epidemiological studies of thyroid cancer and other thyroid diseases in persons exposed to radionuclides from the Chernobyl accident and to fallout from nuclear weapons testing.

Semipalatinsk Nuclear Test Site, Kazakhstan
A study of thyroid disease prevalence and radiation dose in a cohort of subjects exposed to radioactive fallout from the Semipalatinsk Nuclear Test Site in northeastern Kazakhstan.

Thyroid Disease in Young Persons Near Chernobyl
Long-term studies of thyroid cancer among children and adolescents exposed to radioiodines in Ukraine and Belarus following the Chernobyl nuclear accident.

Techa River
