<strong>INTRODUCTION</strong>

During paediatric interventional cardiology (IC) procedures, patients and medical staff can be exposed to relevant levels of radiation (Thierry-Chef <em>et al</em>., 2006; ICRP 103, 2007; ICRP 117, 2010; ICRP 120, 2013). Therefore, optimization programs on radiation safety, including the characterization of dose, x-ray image quality, imaging systems, measurement of patient doses (including the estimation of organ and effective doses), optimization audits using diagnostic reference levels (DRLs) and measurement of occupational doses should be a priority (ICRP 103).

A successful approach to reducing radiation exposure is the measurement of incident air kerma (IAK) or entrance surface air kerma (ESAK) (with backscatter) (ICRU 74, 2005) for patients, and scattered doses or dose rates at the eye’s and lower extremities for the staff, under real or simulated conditions using phantoms and defined technique factors. Applying the attenuation factors for protective devices can enable estimation of the eye lens and lower extremities doses for operators (Ubeda <em>et al</em>., 2016; 2017a).

The International Atomic Energy Agency (IAEA), from 2008 has implemented a pilot study on paediatric radiation protection in cardiology for Chile, as part of three technical cooperation projects entitled “Strengthening Radiological Protection of Patients in Medical Exposures (TSA3), RLA/9/057”, “Ensuring Radiological Protection of patients during medical exposures (TSA3), RLA/9/067” and “Strengthening National Infrastructure for End-Users to Comply with Regulations and Radiological Protection Requirements, RLA/9/075- output 4 (Sánchez <em>et al</em>., 2016).

This paper aims to show the main results achieved in Chile during the years following the Bonn Conference, on paediatric IC procedures and discuss further actions to improve radiation safety in this medical practice.
