RADIATION TREATMENT SYSTEM AND METHOD

摘要

A radiation treatment unit having an elongated shape and a central longitudinal axis comprising: (a) a first pipe assembly comprising: a first coiled pipe for passing therethrough a fluid to be treated and having a first coil inner cylindrical surface defining a first cylindrical cavity; a first radiation source disposed within the first cylindrical cavity; and a first support assembly supporting at least said first coiled pipe, and (b) a second pipe assembly comprising: a second coiled pipe for passing therethrough a fluid to be treated and having a second coil inner cylindrical surface defining a second cylindrical cavity, a second radiation source disposed within the second cylindrical cavity; and a second support assembly supporting at least said second coiled pipe; said second pipe assembly being configured to be coaxially inserted within said first cylindrical cavity so that the second coiled pipe is disposed between said first radiation source and said second radiation source, so that a fluid passing through the first coiled pipe is exposed to an inside radiation of the first radiation source and a fluid passing through the second coiled pipe is exposed to an outside radiation from the first radiation source and an inside radiation from the second radiation source.
