Multiple indicators of ambient and personal ultraviolet radiation exposure and risk of non-Hodgkin lymphoma (United States) (2010)
 The role of ultraviolet radiation (UVR) exposure in the occurrence of 137 first primary non-Hodgkin lymphoma (NHL) cases among 64,102 radiologic technologists was examined. NHL risk was not associated with self-reported time spent outdoors in the summer; however, risk was non-significantly lower with higher average annual and winter ambient UVR. Findings are consistent with previous reports of a protective effect of UVR on risk of NHL.
Incidence of haematopoietic malignancies in US radiologic technologists (2005)
 In a study of 41 cases of leukemia other than chronic lymphocytic leukemia (CLL), radiologic technologists who worked 5 or more years before 1950 and those who held patients 50 or more times for x-ray examination appeared to have a higher risk of leukemia. Leukemia risk was not related to year or age first worked, number of years worked in more recent periods, total number of years worked, specific procedures performed or equipment used, or personal radiotherapy. Working as a radiologic technologist was not linked with risks for multiple myeloma, non-Hodgkin's lymphoma, Hodgkin's lymphoma, or CLL.
