Carcinogenic Properties of Ionizing and Nonionizing Radiation Volume I - Optical Radiation
Silba Cunningham-Dunlop, Bruce H. Kleinstein · 1977
Government scientists were studying cancer risks from non-ionizing radiation including optical sources back in 1977.
Plain English Summary
This 1977 NIOSH technical report examined the carcinogenic properties of both ionizing and non-ionizing radiation, with this first volume focusing specifically on optical radiation (visible light, infrared, and ultraviolet). The research aimed to assess cancer risks from various forms of electromagnetic radiation across the spectrum. This represents early government recognition that radiation health effects extend beyond just nuclear sources.
Why This Matters
This NIOSH report marks a pivotal moment in radiation health research - 1977 was when federal health agencies first systematically examined cancer risks from the full electromagnetic spectrum, not just nuclear radiation. What makes this significant is the inclusion of non-ionizing radiation alongside ionizing sources, acknowledging that lower-energy EMF could potentially cause biological harm through mechanisms beyond direct DNA damage.
The focus on optical radiation is particularly relevant today as we're surrounded by LED screens, laser devices, and intense artificial lighting. While we often think of EMF health concerns as starting with cell phones, this research shows government scientists were investigating non-ionizing radiation effects decades earlier. The science demonstrates that official awareness of potential EMF health risks has a much longer history than most people realize.
Finding
Skin cancer accounts for about 40% of all malignant lesions in the United States (Urbach, 1977) and for approximately 50% of all cancer in Australia (Belisario, 1972 a). It is the most common form of cancer occurring in light-skinned populations (Emmett, 1973; Urbach, 1971; Elwood et al., 1974; Macdonald, 1975).

Exposure Information
Specific exposure levels were not quantified in this study.
Study Details
to identify and document radiation types which have been shown to be actual or potential carcinogens; to review recent findings regarding current substantive issues and impressions of distinguished investigators regarding the types of cancer induced by radiation, carcinogenic dose-response relationships, radiocarcinogenic mechanisms, and synergistic (co-carcinogenic) effects; to predict the expected excess of cancers (or, for potentially carcinogenic types of radiation, the potential risk of cancer) either under commonly encountered conditions of occupational exposure or at the currently accepted maximum permissible dose limits; and to identify specific gaps in the present knowledge of radiation carcinogenesis, and to recommend specific areas in need of further investigation.
