US Radiologic Technologists Cohort
Initiatives
-
The key goal of the study is to understand how repeated low-dose occupational ionizing radiation exposures, such as those potentially experienced by radiologic technologists, are related to cancer and other health conditions. The study objectives are:
1. Assess risks for cancer and other diseases from long-term low-dose occupational and personal medical ionizing radiation exposures;
2. Assess risks for cancer and other diseases from occupational exposures among technologists who perform nuclear medicine and fluoroscopically guided diagnostic interventional procedures;
3. Assess risks for skin and other cancers from solar ultraviolet radiation exposures;
4. In pooling studies with other epidemiologic studies replicate main genotype effects for breast cancer reported from genome-wide association studies

Design
- Study design
- Population cohort
- Follow Up
- The study conducted four major surveys during 1983-2014. Additionally, follow-up questionnaires were sent to Fourth Survey responders who reported working with radioisotope or fluoroscopically-guided procedures to obtain more detailed information about work practices and exposures related to these procedures.
