A study of dose gamma ray buildup factor for water using different methods

الملخص EN

The dose gamma ray buildup factor for water has been studied using computer programs, which constructed to calculate this factor for water using different methods (Taylor's, Berger's and Capo's formulae) for point isotropic source.

The results of this study have been compared with the standard previous publishing results.

The study shows that the buildup factor depends on thickness of the shield and energy of the radioactivity source.

Key words: Dose gamma ray for point isotropic source-Dose gamma ray buildup factor-Taylor’s formula- Berger’s formula-Capo’s formula.
