A reactor system for decontamination of water by photolytic oxidation utilizing near blackbody radiation, the system comprising (1) a reaction chamber defining an internal space with an inlet and an outlet; and (2) a broadband radiator for generating radiant energy with wavelengths between about 150 nm and about 3 .mu.m, the broadband radiator disposed within the reaction chamber, such that a sufficient dosage of broadband radiation irradiates the contaminants and/or the oxidant within the internal space of the reaction chamber thereby causing photolytic oxidation of the contaminants by direct action of the radiation on the contaminants to break chemical bonds by sustaining a free radical chain reaction of oxidizing components, thus breaking down the contaminants by way of atomic abstraction of the components of the contaminants. In preferred embodiments, at least a portion of the radiant energy is generated in a pulsed mode, such as between about 1 and about 500 pulses per second. In preferred embodiments, the broadband radiator generates radiant energy at a rate of between about 1 kW and about 10 MW., and the resultant dosage rate of broadband radiation is between 1 joule/cm.sup.2 and about 5000 joules/cm.sup.2. In preferred embodiments, the radiant energy is produced by at least one gas filled flashlamp having a gas plasma temperature of between about 9,500.degree. K and about 20,000.degree. K.
