The purpose of this project is to generate refined leukemia risk estimates and risk assessment results to serve as the basis for evaluating the adequacy of occupational exposure for ionizing radiation standards.
The long-term goal of the project is to ensure that the cancer risk associated with occupational exposure to radiation is managed using standards based on health effects observed from workplace exposure conditions. The overall objective is to assess the adequacy of current occupational radiation exposure limits using the most precise and relevant estimates of cancer risk from epidemiologic studies. This objective will be achieved through development of improved, occupationally-based quantitative risk estimates for leukemia radiogenicity. The project will improve leukemia risk estimates by using a large base cohort and adjusting for benzene exposure for most study subjects. These estimates will be used in conjunction with appropriate occupationally-based risk estimates for other radiogenic cancers derived from the International Agency for Research on Cancer (IARC) 15-country study of nuclear workers to assess the adequacy of occupational exposure standards. The overall objective is critical to 1) establishing occupational ionizing radiation exposure standards that adequately protect workers and 2) facilitating appropriate decisions for workers who apply for compensation under existing Federal programs.
According to estimates by the National Council for Radiation Protection, approximately 1.5 million United States workers across numerous occupational sectors are occupationally exposed to ionizing radiation each year. Affected sectors include manufacturing, health care, transportation, and services. Financial costs to these sectors from worker illnesses associated with occupational exposures include sick leave and disability pay, loss of trained personnel to disability or death, and worker compensation awarded under federally mandated programs for those deemed likely to have developed malignancies as a result of their occupational radiation exposures.
