Determinación de la dosimetría de radiación externa en pacientes con hipertiroidismo y cáncer de tiroides tratados con IODO-131 en el Área de Medicina Nuclear del Hospital “Carlos Andrade Marín” IESS – Quito.

Abstract

The aim of the titling work was to determine the external radiation dosimetry in patients with Hyperthyroidism and Thyroid Cancer treated with iodine-131 in the Nuclear Medicine Area of the "Carlos Andrade Marin" IESS-Quito Hospital (HCAM) period October 2017 to February 2018. For this purpose, the Geiger Muller Thermo Scientific detector, located one meter away from the neck, abdomen and lungs, was used. The patients under study were classified into two groups: group I corresponded to patients with hyperthyroidism and group II patients with thyroid cancer. In the case of patients with thyroid cancer, the medical procedures carried out were taken into account. Almost total thyroidectomy, Total thyroidectomy and the stage of the disease. The results show that the values obtained from dose rate for stage of the disease. The results show that the values obtained from the dose rate for both groups of patients do not exceed 35 microsievert/h recommended by international organizations for radiological discharge. These dose rate values are suggested to be analyzed and considered by the radiological safety and security office of HCAM.
