The present invention discloses a methodology for the characterization and determination of mixed-field dosimetry for <252>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 <252>Cf medical sources. A dosimetry protocol, similar to that utilized for ICRU-45, with parameters determined specifically for <252>Cf brachytherapy is disclosed. Neutron isodose distributions and data necessary for clinical implementation of <252>Cf AT sources are also disclosed herein. Additionally, novel methods for the encapsulation, storage, and delivery/implantation of <252>Cf radionuclide sources are disclosed.
