Emitted spectra, which is an input of the MCNP source description and decay scheme of isotopes. and stand for the half-life of and the maximum energy of emitting betas, respectively.
Schematic (cross-sectional view) of a proposed ophthalmic applicator and voxels (shown as an array of squares) used in MCNP simulations to determine dose distributions.
Differences in absorbed dose rates calculated by the default MCNP and ITS energy indexing algorithms for P-32 ophthalmic applicators.
Depth dose distributions along the central axis distance from the surface for P-32 and ophthalmic applicators. A distribution was adopted from Ref. 13.
Dose profile near the surface ( from the surface) of a proposed P-32 ophthalmic applicator.
Isodose curves near a proposed P-32 ophthalmic applicator, where neighboring curves have the same dose difference in logarithmic lethargy.
