In a system and method for disinfecting a surface of an object with iodine-laden gas, a carrier gas generation means generates a gas stream, which is then directed into a chamber that includes an iodine source. As the gas stream enters and passes through the chamber, iodine is drawn and absorbed into the gas stream, creating an iodine-laden gas that exits the chamber. The carrier gas stream is humidified prior to or after its interaction with the iodine source. In some embodiments, the iodine-laden gas then travels from the chamber and is directed into an enclosure when it interacts with microbes contained on a surface of an object housed within the enclosure or otherwise engaged by the enclosure. In other embodiments, as the iodine-laden gas exits the chamber, it is directed to a nozzle, via which the iodine-laden gas is applied to the surface of the object to be disinfected.
