US 2013/0240761 A1 · SELF-FOCUSING RADIOACTIVE SOURCE DEVICE AND RADIATING APPARATUS EMPLOYING THE SAME

Abstract

A self-focusing radioactive source device and a radiating apparatus employing the same are disclosed. The self-focusing radioactive source device includes: a source capsule; a source body disposed in the source capsule; and M radioactive sources arranged in the source body, wherein radioactive rays emitted from the M radioactive sources in the source capsule are focused on a common focus, and wherein M is a natural number greater than 1. The self-focusing radioactive source device and the radiating apparatus can greatly reduce the volume and weight of the source body, obtain a small penumbra and small focus radius, and provide flexible incident angles and wide applications.
