In nuclear medicine, the dose received by the critical organs becomes important due to the
radioisotopes placed inside the body. Medical applications are among the main causes of radiation
exposure to the general population. In these applications, Computed Tomography (CT) scans are the
primary source, while nuclear medicine is the second largest. The informed decisions that must be
made regarding the use of nuclear medicine procedures require a better understanding of the absorbed
radiation dose and the associated risks. In this study, when iodine radioisotope I-131 inserted into the
thyroid gland of boys aged 0, 1, 5, 10 and 15, change of the absorbed dose of the thyroid gland, thymus
and lymph nodes was investigated by the Monte Carlo based NCINM (National Cancer Institute
Dosimetry System for Nuclear Medicine) code.
