Irradiator apparatus and method

An irradiator of the type using a radioactive material as a source of radiation is combined with a gaseous liquid contact chamber. The irradiator has a casing having an input and output therefrom and a plurality of connected chambers formed in the casing and separated by walls having an opening therethrough. A plurality of gamma radiation sources are located in a plurality of the chambers, thus forming a plurality of irradiation chambers. At least one of the chambers is a gas treatment chamber having a gas input line connected thereto to provide gas liquid contact in the gas treatment chamber. The walls between the irradiation chambers and the gas treatment chambers are made of a gamma radiation blocking material, such as lead or concrete. Gas escape lines are provided for preventing the build up of gas in the chambers, so that a fluid can be treated through a series of irradiation gas contact treatments. Gas lines can also be provided directly into the irradiation chambers. Gases such as ozone, oxygen, air and chlorine may be utilized for the liquid gas contact treatment. A method is provided for the irradiator to irradiate fluid from an output of an industrial process to produce gas and liquid streams from the molecular dissociation of a portion of the waste fluid, then to collect the streams from the molecular dissociation of the waste and feed the collected streams from the molecular dissociation back into the production chain process of the industrial plant producing the waste, so that a portion of the waste can be reused by the industrial plant
