Abstract

In the irradiation of products such as foods and therapeutic substances to destroy bacteria or virus therein, radiation of a frequency exceeding 107 cycles per second is applied with an intensity which if continued would produce detrimental heat effects, the radiation being however applied in pulses so short that detrimental heating does not occur. The pulses are preferably flat-topped; in the case of infrared and ultra-violet rays they may be produced by a revolving shutter and in the case of radio waves and X-rays by known modulating devices. Preferably the period of treatment exceeds the duration of the life-cycle of the organisms to be killed and the interval between pulses is shorter than that part of the cycle in which the organism is most sensitive. In an example blood serum is irradiated by a mercury vapour lamp fed with a current having a pulse length of 200 microseconds and a pulse recurrence frequency of 1,000 per second, whereby the temperature of the serum does not rise above 30 DEG C. Specification 538,361 is referred to.
