Abstract

An apparatus decontaminates a radioactively contaminated surface region of a pipe, connector or vessel being open at one end, with a dry mechanical blasting medium. The apparatus includes a processing bell to be mounted on the open end of the pipe, connector or vessel. A flexible dustproof duct is connected to the processing bell. A retaining device protrudes into the duct and is movable from outside in the interior of the pipe, connector or vessel. A blasting head is disposed on the retaining device. A blasting system is connected to the blasting head and has a continuous circulation of the blasting medium.
