This paper presents dose calculations due to oxidation-driven mobilization of a vanadium alloy, V-4Cr-4Ti, exposed to air. We concentrate on air because it is highly unlikely that the vanadium alloy will be used with a water coolant. We calculate the offsite dose using data from transpiration tests together with information from activation calculations and the radiological hazard of the material from a dose code. We compare the early dose as a function of temperature from V-4Cr-4Ti with the early dose from tungsten, copper, 316SS, and a low activation ferritic steel. The vanadium alloy dose is almost an order of magnitude lower than the dose from the other materials for the entire temperature range examined, 600-1200°C.
