Radiation Exposure Risks Associated with Medical Imaging
Radiation Exposure Risks Associated with Medical Imaging is a Continuing Professional Development (CPD) course designed for healthcare professionals working in radiology, nursing, general practice, emergency medicine, medical imaging, oncology, paediatrics, and community healthcare settings. The course provides an evidence-based overview of ionising radiation exposure related to medical imaging, associated health risks, patient safety considerations, and informed clinical decision-making. Medical imaging plays an essential role in modern healthcare by supporting diagnosis, treatment planning, and disease monitoring. However, certain imaging modalities such as X-rays, computed tomography (CT), fluoroscopy, and nuclear medicine expose patients to ionising radiation, which may contribute to cumulative health risks over time. Understanding the balance between clinical benefit and radiation exposure is critical for safe and effective patient care.

Frequently Asked Questions
Ionising radiation is energy that can remove electrons from atoms and potentially damage human tissue.
X-rays, CT scans, fluoroscopy, and nuclear medicine procedures commonly involve ionising radiation.
Children have rapidly developing tissues and a longer lifespan during which radiation effects may develop.
No. Ultrasound and MRI do not use ionising radiation.
Repeated imaging over time may increase long-term health risks, including cancer risk.
Radiation safety focuses on justification of imaging and minimising exposure while maintaining diagnostic quality.
