One of the primary challenges faced by operational personnel at the Tehran Research Reactor (TRR) is the handling and management of spent fuel assemblies. Estimating the radiation dose from these fuels in the air is crucial for assessing risks and implementing necessary safety measures during transportation. Due to the high radiation intensity and dose rates of spent fuels, direct measurement of their airborne dose rate is impractical. Instead, the dose rate is measured within the reactor pool water and then converted to an estimate for the air using conversion factors. This research focuses on estimating the dose conversion factor from water to air for gamma rays emitted by spent fuels at TRR. Experimental data from a fission molybdenum source and Monte Carlo simulations using the MCNP code were utilized to determine this conversion factor. The results obtained from both methods demonstrate relatively good agreement with each other.
