Roger D. Caldwell Archives 

*	Roger Dale Caldwell, Ph.D., was a pioneering health physicist

who worked in the Health and Safety Group at the Nuclear Materials and

Equipment Corporation (NUMEC) in Apollo, Pennsylvania, during the 1960s

and into the 1970s. Roger struggled with the challenges of protecting

workers from intakes of uranium and plutonium and measuring how well

protection had succeeded using bioassay, air samples, and workplace

indicators. He showed that traditional indicators were not adequate, and

developed new means to monitor workers that were adequate. 

*	He received the Health Physics Society's Elda E. Anderson Award

in 1973. 

*	Roger Caldwell left NUMEC in the early 1970s and joined the

faculty of the Department of Radiation Health at the University of

Pittsburgh Graduate School of Public Health. Some of the papers linked

below were salvaged from the trash at Pitt in the early 1990s when the

department began relocating off-campus. Others listed can be found in

publications. The unpublished papers are reproduced here out of respect

for the legacy of this forward-thinking individual. 

*	Roger Caldwell died in 1974 at the age of 39.
