Abstract
Abstract The invention relates to a method and an ap- p aratus for frequency selective irradiation of biological materials and particularly tissues, cells and/or cell components of living organisms, in particular of human and animals, by irradiating a component element of the target material at the corresponding Mossbauer absorption frequency. The component radiation absorption at the Mossbauer absorption frequency is thus enhanced many times over the absorption of the surrounding material having a different Mossbauer absorption frequency. The energy thusly absorbed by the target material component is converted to and remitted as Auger electrons, which provide intranuclear radiation resulting in lethal double strand breaks in the DNA molecules of the target tissue. The irradiation is administered in frequency and material selective modes of treatment, and may be combined with conventional chemotherapeutic agents to provide a further enhanced treatment modality. Moreover, the source frequency can be adjusted to enhance the killing effect. The method of apparatus according to the present invention are useful in combination with naturally occurring or administered pharmaceutical stable isotope absorbers, having significantly reduced side effects by comparison to conventional chemotherapy or radiation therapy. The method and apparatus according to the invention can be applied for selective radiation therapy providing selective tissue damage or necrosis, in particular for cancer therapy, and for differentiating between diseased and normal tissues.
