ABSTRACT:
A method and apparatus of creating a miniaturized source of radiation and delivering radiation to a location such as therapy location. The radiation source comprises a member made of a material emitting electrons when energy is supplied to the member. There is an electron retarding member disposed opposite the electron emitting member, and the electron retarding member is made of a material emitting ionizing radiation when electrons are retarded therein. The radiation source is further provided on an elongated member in the distal region thereof, and the elongated member is insertable into the body.
