Radiation Protection of Patients

Radiation Protection Of Patients

Patients are exposed to ionizing radiations when they undergo diagnostic examinations using x rays or radiopharmaceuticals, therapy of cancer or benign lesions using radiations emitted by radioisotopes or those by radiation generators; and in interventional procedures using fluoroscopy. There is a tremendous increase in use of ionizing radiation in medicine during the past two decades. Health professionals and patients are concerned about harmful effects of radiation. International Atomic Energy Agency (IAEA) has established a programme on radiological protection of patients in recognition of increasing importance of this topic. The emphasis in the past had been on radiation protection of staff and this emphasis has helped to reduce radiation doses to staff to levels much below the dose limits prescribed by the International Commission on Radiological Protection (ICRP) and accepted by most countries. The recent emphasis on radiation protection of patients is helping in developing strategies to reduce radiation doses to patient without compromising on diagnostic or therapeutic purpose.
