Methods and systems for shaping the radiation distribution profile of a protected radiation source used for treating medical conditions

A system for providing a radiation source producing a radiation field, the system comprising:

• a radioactive source with a first geometry and first perimeter defining its first geometry, the radioactive source having material generally spanning an area bounded by the first perimeter, the radioactive source having a first thickness dimension and a first width dimension, the radioactive source comprises a source that emits beta radiation particles;
• and
• a container for enveloping the radioactive source, the container having a second thickness dimension and a second width dimension, the second thickness dimension being greater than the first thickness dimension, the second width dimension being greater than the first width dimension, the container being formed from a three dimensional printing process and a three dimensional printed material, the three dimensional printed material comprising a metal impregnated compound, the container further comprising a contour that makes the second thickness dimension an irregular shape and causes variable dose rate emissions across a face of the radioactive source.
