Comparison of different computer speeds in calculating of Co 60 depth doses by MCNP4A and MCNP4B Monte Carlo codes

Background and Objective: MCNP is a general-purpose Monte Carlo code that is used for simulating of neutrons, photons and electrons transport in different media. Recently this code has been used for radiotherapy dosimetry and treatment planning. In recent investigations, the reasonable run-time was...

Percent depth dose of CO60 gamma rays in water phantom for 10×10 cm was calculated by each computer. Findings: The time required to computer the PDD by F6 tally was 60 times greater than the F8 tally. In all the cases, the 4A version was approximately 5% faster than 4B version.
