The invention relates to a beta-
ray multifunctional treatment method, which comprises the following steps: externally irradiating a diseased region for 1-30 minutes at a
short distance by utilizing beta-rays; wherein a beta-
ray multifunctional therapeutic apparatus comprises a therapeutic probe, a
therapeutic window, a
radioactive source and a protective cover, the therapeutic probe comprises a probe outer wall and a protective
bottle, the
therapeutic window is arranged in the protective
bottle, one side of the probe outer wall, one side of the protective
bottle and one side of the therapeuticwindow are flush, and a protective material layer is arranged on the outer wall of the
therapeutic window; the protective cover comprises a protective outer wall and a protective layer, the protective outer wall is correspondingly matched with the flush side of the probe outer wall, and the protective layer corresponds to the protective bottle; wherein the
radioactive source is a surface
radiation source, the number of the protective
layers is more than two, and the thicknesses of the protective
layers are gradually increased along the
irradiation direction of the
radioactive source. The method is simple in operation, quick in effect, good in
curative effect, lasting in effect, low in dosage, free of side effects and wide in application range,
nuclear medicine is extended to the aspect oftreating frequently-occurring diseases of common diseases, a
nuclear medicine treatment range is greatly extended, and the method is an important discovery and innovation of
nuclear medicine.
