The SEECAL program calculates radiation dose factors (S values) for internal radionuclide exposure using ICRP methodology. Updated versions utilize advanced voxel phantoms for improved accuracy in dose estimations.

Area of Science:

  • Medical Physics
  • Radiation Dosimetry
  • Nuclear Medicine

Background:

  • The SEECAL program estimates internal radiation dose.
  • It uses specific absorbed fractions (SAF) derived from anthropomorphic phantoms.
  • Its methodology aligns with the International Commission on Radiological Protection (ICRP).

Purpose of the Study:

  • To describe the SEECAL computer program for calculating specific effective energies (S factors).
  • To detail its dosimetric methodology based on ICRP guidelines.
  • To present a revised version utilizing new voxel-based phantoms.

Main Methods:

  • SEECAL calculates S factors using specific absorbed fractions (SAF).
  • SAF data are derived from MIRD-type anthropomorphic phantoms.

  • A revised version uses Monte Carlo methods for photon SAFs from voxel-based phantoms.

    • Main Results:

    • SEECAL calculates S factors for various age groups (adults and paediatrics).
    • The program has been widely used for occupational and public dose estimations.
    • A revised version is limited to adults and uses new voxel phantoms.

    Conclusions:

    • SEECAL is a valuable tool for internal dose assessment.
    • The use of voxel-based phantoms in the revised version enhances dosimetric accuracy.
    • The program supports dose calculations for nuclear medicine procedures.
