Abstract
The present invention discloses a methodology for the characterization and determination of mixed-field dosimetry for Cf Applicator Tube (AT)-type medical sources, utilizing ionization chambers, GM counters, and Monte Carlo methods. Unlike the previous methodologies, the present invention discloses a specification of dose to muscle, rather than dose to water, for clinical dosimetry of Cf medical sources. A dosimetry protocol, similar to that utilized for ICRU-45, with parameters determined specifically for Cf brachytherapy is disclosed. Neutron isodose distributions and data necessary for clinical implementation of Cf AT sources are also disclosed herein. Additionally, novel methods for the encapsulation, storage, and delivery/implantation of Cf radionuclide sources are disclosed.
