This work provides a dosimetric study in radioiodine therapy in a patient with DTC for absorbed dose estimation in bone marrow post therapeutic treatment. The objective concerns the provisional dosimetry suitable for administering patient-specific activities. According to the Medical Internal Radiation Dose schema, whole-body measurements with a ionization chamber, and blood samples measurements using an activity calibrator, after therapeutic administration, in different times were performed. Considering our results, the patient could have received an activity of I-131 at least four times higher than the given one, while respecting the maximum adsorbed dose to the blood, that does not exceed 2 Gy.
