Knowledge of Radiation Hazards and Attitude toward Radioprotection among Radiography Healthcare Professionals

Abstract

Diagnostic and interventional imaging are essential to modern care but expose staff to ionizing radiation. International guidance emphasizes justification, optimization, and dose limitation; however, practical knowledge and routine monitoring among healthcare workers often remain suboptimal. This study assessed knowledge of radiation hazards and attitudes toward radioprotection among radiography healthcare professionals at a large tertiary centre in Karachi. Methods: We conducted a descriptive cross-sectional study in the Radiology Department of Jinnah Postgraduate Medical Centre over a three-month period. A structured questionnaire captured demographics, training, knowledge of dose limits and signage, availability and use of protective equipment, personal dosimetry, and attitudes toward safety policies. Descriptive statistics were computed, and associations were tested using the chi-square test (α = 0.05). Results: Of 101 respondents, most were early‑career. While bare shielding (lead apron/thyroid collar) was widely available and used, formal training on radioprotection was uncommon, and over half did not use a personal dosimeter. Knowledge of annual occupational dose limits was moderate, but many were uncertain about how exposure and dose are measured. Staff working in operating and endoscopy suites reported more frequent fluoroscopy exposure than those in radiology suites. Attitudes were positive, with a strong willingness to adopt additional safety measures if training and institutional support were provided. Conclusions: Gaps in practical knowledge, formal training, and routine exposure monitoring persist despite positive attitudes toward these areas. Institutional priorities should include mandatory periodic training, universal personal dosimetry with review and feedback, and robust policy enforcement.
