Abstract

A method and apparatus of creating a miniaturized source of radiation and delivering radiation to a location such as a therapy location. The radiation source includes 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 a distal region thereof, and the elongated member is insertable into the body.
