Building Trades National Medical Screening Program

BTMed video screen shotThe Building Trades National Medical Screening Program (BTMed) provides free medical screening services to construction workers formerly employed at Department of Energy (DOE) nuclear weapons sites, who may be at risk for occupational illnesses.

Since 1996, BTMed has provided nearly 40,000 medical screening exams and 6,400 low-dose CT scans to these workers. It offers conventional screenings, as well as an early lung cancer detection (ELCD) program. BTMed screens workers from 35 DOE sites through a network of more than 225 specially credentialed health clinics across the country.

Workers at these sites may have been exposed to occupational hazards such as radiation, asbestos, beryllium, cadmium, chromium, lead, silica, and solvents, which can cause cancer and other serious, even fatal, health problems. The medical screening exams are designed to identify work-related health conditions at an early, more treatable stage and provide information that improves the workers understanding of their health and well-being. Ongoing medical surveillance can also identify trends and benefit the occupational health and safety of future workers.

BTMed is part of the Department of Energy’s Former Worker Program (FWP) and is administered by CPWR.
