The International Atomic Energy Agency initiated a program in 2001 on Radiation Protection of Patients which included many actions to reduce patient doses in computed tomography without compromising image quality. The hallmark has been international cooperation under the International Action Plan for the Radiological Protection of Patients. Specific actions included a survey of practice in developing countries in terms of justification and optimisation in CT, frequency of adult and pediatric CT examinations, availability and use of imaging protocols, dose tracking initiative, development and dissemination of training materials and activities in the area of radiation protection in new computed tomography-based imaging modalities, all on a global scale. The achievements of the International Action Plan, which include harmonised training material, guidance documents, a number of publications, a website on radiation protection of patients ( and a series of actions in developing countries that have shown positive impacts on patient protection, are summarised in this chapter. Such large-scale multi-national studies are the first of its kind and provide good insight into the situation and opportunities for improvement.
