ABSTRACT
Interventional radiology and interventional cardiology are important in the diagnosis and treatment of many diseases. Both disciplines involve working in a unique medical environment that involves exposure to ionising radiation. This chapter provides an overview of radiological protection practices, including the principles applied to the use of radiation and measurement of radiation dose. Basic information required to protect patients and staff in the cardiac catheterisation laboratory, along with some practical limitations of radiation dose monitoring, are also provided. Natural and artificial sources of radiation are discussed, including the typical radiation doses expected from each source, plus an outline of radiation effects and safety measures for the operator, assistants, and the patient. A summary of recommendations for safe fluoroscopy practice is included.
