Specialty	Typical Occupational Dose Range (per year)	Main Cancer Signals	Key Citations
Interventional Radiology (IR)	Low-to-moderate; varies with shielding and case complexity	No strong increase in modern cancer mortality; modeled lifetime cancer risk small but nonzero	[1,3,4]
Interventional Cardiology (IC)	Higher cranial dose due to operator positioning	Reports of left-sided brain tumors; elevated head/neck scatter exposure	-6
Radiologic Technologists (RTs)	Variable; cumulative dose may be substantial	Increased brain cancer mortality; increased melanoma; increased breast cancer	[2,5]
Vascular Surgery	Variable depending on shielding and OR layout	Limited epidemiologic data; chromosomal or DNA damage reported in some studies	-
Nursing / Anesthesia Personnel	Generally lower than physician operators; varies with proximity during monitoring	Limited epidemiologic data; early biomarkers of DNA or chromosomal damage	-

Exposure categories are qualitative and synthesized from published dosimetry and epidemiologic literature rather than direct numerical dose measurements.

Figure 1: Conceptual Diagram of Scatter Radiation during Fluoroscopy

Figure illustrating the primary X-ray beam directed from the X-ray tube toward the patient, along with concentric rings representing decreasing scatter radiation intensity as distance increases. The operator stands in the typical position adjacent to the patient, showing how proximity influences exposure. Ceiling-suspended shielding and other barriers (not shown) can further reduce scatter dose. This conceptual schematic emphasizes the principle that scatter radiation decreases with distance from the patient.

Figure 2: Relative Occupational Radiation Exposure across Fluoroscopy-Guided Specialties

Bar graph comparing approximate exposure levels among interventional radiologists, interventional cardiologists, radiologic technologists, vascular surgeons, and peri-procedural nursing/anesthesia staff. Values were derived qualitatively by synthesizing exposure trends reported in Lee et al. (1), Rajaraman et al. (2), Niklason et al. (3), Fetterly et al. (7), and Rozgaj et al. (10). These relative exposure categories reflect qualitative comparisons and are not intended to represent exact numerical dose values. Exposure categories are illustrative and intended for comparative purposes rather than representing precise dose measurements.
