User's manual for ALDOSE: A computer code for calculating absorbed-dose rate, dose-equivalent rate, and dose-weighted LET as functions of depth in water irradiated by an alpha disc source.

摘要

ALDOSE is a Fortran computer code written to calculate the absorbed-dose rate, dose-equivalent rate, and dose-weighted LET as functions of depth in water irradiated by a uniform alpha disc source. In addition, the average LET and average quality factor for the irradiated water are computed. The program accommodates a source upon which a layer of gold may reside and which may be separated from the water by a sheet of Mylar. The presence of gold and/or Mylar is optional and must be specified by the user. ALDOSE can process a source having up to 12 alpha energies ((le)15 MeV) in its spectrum. Lateral dimensions of the source are assumed to be large when compared to alpha-particle ranges in water. Calculations are based on range-energy tables for alphas in gold, Mylar, and water and employ a technique of ray tracing. Output data are tabulated as histograms and graphs in files which can be accessed by the user for further processing and plotting.
