Health Risk From Radioactive Iodine (RAI) Therapy And Medical Imaging- A Short Review

Different role of radioactive iodine (RAI) has a different dosage. RAI is the effective treatment for cancer but has a short or long side effects such as xerostomia and loss of taste or smell. Ablation, adjuvant and therapeutic is the role of RAI and all of it has risk. RAI tend to increase the survival for the patient on progression-free survival and disease- free survival.  Aside from that, computed tomography radiation has been associated to a small but significant increase in the chance of fatal cancer during a person’s lifetime. This review aims to promote public awareness and lead initiatives to eliminate unneeded computed tomography scans. Despite evidence of recognized hazards of radiation-related computed tomography and cancer induction, the usage of pediatric computed tomography continues to rise. In the United States of America, more than 60 million computed tomography scans are projected to be conducted each year, with 7 million of those being performed on children. To decrease radiation exposure, pediatric radiologists employ the ALARA ('as low as reasonably achievable') concept. This idea is reinforced through education and lobbying directed towards recommending physicians. Clinical strategies that restrict computed tomography scanning and encourage non-radiation imaging modalities like ultrasound and magnetic resonance imaging might help decrease radiation exposure even further. Although individual risk estimates are tiny, the widespread use of computed tomography in the community may result in future public health concerns.
