Exposure to ionizing radiation is a consequence of many diagnostic and interventional cardiac procedures. Radiation exposure can result in detrimental health effects because of deterministic (eg, skin reaction) and stochastic effects (eg, cancer). However, with the levels experienced during cardiac procedures these risks can be difficult to quantify. Healthcare providers and patients might not fully appreciate radiation-related risks. Though in many cases radiation exposure cannot be avoided, a practice of minimizing exposures to levels "as low as reasonably achievable" (ALARA principle) without compromising the utility of the procedure is encouraged. The purpose of this document is to inform health care providers on the key concepts related to radiation risk from common cardiac procedures and provide specific recommendations on ensuring quality of care.
接触电离辐射是许多诊断和介入性心脏程序的后果。由于确定性（例如皮肤反应）和随机性效应（例如癌症），辐射暴露可能会导致有害的健康影响。然而，由于在心脏程序中经历的水平，这些风险很难量化。医疗保健提供者和患者可能不完全了解与辐射相关的风险。尽管在许多情况下无法避免辐射暴露，但鼓励在不影响程序效用的情况下，将暴露水平“尽可能低”（ALARA 原则）降至最低。本文件的目的是向医疗保健提供者通报与常见心脏程序相关的辐射风险的关键概念，并就确保护理质量提供具体建议。
