The goal of this project is to determine the absorbed dose of radiation to a patient using 99mTc-MAA as a tracer for a lung scan using the MIRD formula accounting only for the radiation dose contributed by the target organ. The radiation dose for other organs to the target organ is considered negligible as the uptake of 99mTc-MAA from other organs is less than 1%. In addition to calculating the absorbed dose of radiation, the initial dose rate was also calculated by back solving to determine the total mass of the lungs. The radiation dose to the patient by the target organ was calculated to be 269.44 mrads and the initial dose rate was determined to be 156 mrads/hr.
