Radiologists and radiologic technologists were among the earliest occupational groups exposed to ionizing radiation and represent a large segment of the working population exposed to radiation from human-made sources. The authors reviewed epidemiologic data on cancer risks from eight cohorts of over 270,000 radiologists and technologists in various countries. The most consistent finding was increased mortality due to leukemia among early workers employed before 1950, when radiation exposures…

Historical Review of Occupational Exposures and Cancer Risks in Medical Radiation Workers

There is an urgent need to expand the limited information on average annual, time-trend and organ doses from occupational radiation exposures and to assess lifetime cancer risks of medical radiation workers.

Occupational radiation exposure and cancer incidence in a cohort of diagnostic medical radiation workers in South Korea

Occupational radiation doses were not significantly associated with cancer incidence among South Korean diagnostic medical radiation workers, and cautious interpretation of ERRs is needed due to the limitations of short follow-up and low cumulative radiation doses.

Risk of Occupational Exposure to Ionizing Radiation among Medical Workers in Canada

The result of an increased risk of thyroid cancer among medical workers occupationally exposed to ionizing radiation confirms previous reports.

Ionizing radiation exposure and cancer risk among Norwegian nurses

No firm evidence that nurses potentially exposed to ionizing radiation had increased risk of radiation-related cancer was found, and internal analyses performed with Poisson regression found that the most likely explanation was confounding by smoking.

Cancer Risks in U.S. Radiologic Technologists Working With Fluoroscopically Guided Interventional Procedures, 1994-2008.

Elevated risks of brain cancer, breast cancer, and melanoma among technologists who performed fluoroscopically guided interventional procedures are observed, and exposure to low-dose radiation is one possible explanation for these increased risks, although these results may also be due to chance or unmeasured confounding by nonradiation risk factors.

Radiation Risk to the Fluoroscopy Operator and Staff.

The basics of radiation dose and the potential radiation effects, particularly as they pertain to the operator, are reviewed and the data regarding the risk of each type of radiation effect to the fluoroscopy operator and staff are presented, with special attention on cancer induction, radiation-induced cataracts, and the pregnant operator.

Mortality among Medical Radiation Workers in the United States, 1965-2016.

Medical radiation workers were at increased risk for lung cancer that was higher among men than women, although this difference was not statistically significant, and combining these data with other cohorts within the MPS will enable more precise estimates of radiation risks at relatively low cumulative doses.

Risk of developing cancers due to low-dose radiation exposure among medical X-ray workers in China-results of a prospective study

A significant relationship is found between the risk of malignant tumor and occupational radiation factor in medical diagnostic X-ray workers in China and the relative risk of developing different types of cancers.

Childhood cancer in the offspring born in 1921–1984 to US radiologic technologists

It is found that there is no convincing evidence of an increased risk of childhood cancer in the offspring of RTs in association with parental occupational radiation exposure.

Mortality among United States radiologic technologists, 1926-90

The findings for breast cancer are consistent with a radiation effect, but possible misclassification in exposure (based on number of years certified) and potential confounding associated with reproductive histories preclude a causal conclusion.

Risk of melanoma among radiologic technologists in the United States

Clarifying the possible role of exposure to chronic ionizing radiation in melanoma is likely to require nested case‐control studies within occupational cohorts, such as this one, which will assess individual radiation doses, and detailed information about sun exposure, sunburn history and skin susceptibility characteristics.

There was no evidence of an effect of radiation on diseases other than cancer even in the earliest radiologists, despite the fact that doses of the size received by them have been associated with more than a doubling in the death rate among the survivors of the Japanese atomic bombings.

The study results might suggest that the chronic exposure to low-dose radiation enhanced the risk of lymphatic and hematopoietic cancers.

Cancer and other causes of mortality among radiologic technologists in the United States

The elevated mortality risks for breast cancer and for the combined group of acute lymphocytic, acute myeloid and chronicMyeloid leukemias are consistent with a radiation etiology given greater occupational exposures to ionizing radiation prior to 1950 than in more recent times.

CANCER INCIDENCE AND RISK ESTIMATION AMONG MEDICAL X-RAY WORKERS IN CHINA, 1950–1995

The patterns of risk associated with years since beginning x-ray work and with age and calendar year of initial employment suggest that the excesses of leukemia, skin cancer, and female breast cancer—and possibly thyroid cancer—were related to occupational exposure to x rays.

Breast cancer mortality among female radiologic technologists in the United States.

The high risks of breast cancer mortality for women exposed to occupational radiation prior to 1950 and the subsequent decline in risk are consistent with the dramatic reduction in recommended radiation exposure limits over time.

Does radiation exposure produce a protective effect among radiologists?

Lower radiation exposure may be one of a number of possible explanatory factors for the cross-over from "protected" to "higher risk" status as these physicians age.

Effects of radiation on incidence of primary liver cancer among atomic bomb survivors.

The radiation risk for primary liver cancers between 1958 and 1987 in a cohort of atomic bomb survivors in Hiroshima and Nagasaki, Japan is described and a paucity of cholangiocarcinoma and hemangiosarcoma cases suggested that they are not significantly associated with whole-body radiation exposure.

Several studies indicate a risk of nonmelanoma skin cancer (NMSC) following cancer therapy; however, most of the studies reporting on NMSC have not distinguished between patients who received radiotherapy versus chemotherapy.
