Re:Radiation Shielding Computer Codes

Hmmmmmmm,


      From:    jpreisig@aol.com   



     MCNP (Monte Carlo Neutral-Particle Program) is a program that can

be used for neutron and photon shielding geometries --- the shielding geometries

are user designed and can be highly variable.  MCNP can be obtained from the

RSIC (Radiation Shielding Infromation Center or whatever it is called these

days).  RSIC is at Oak Ridge and Oak Ridge has a web-site.  MCNP can

usually be gotten for a fairly small handling charge.  RSIC also

distributes many other shielding computer codes and has a catalog which

describes these codes.


       Another guess is microshield, but I don't know much about it.


      MCNP can be run on personal computer.  Especially when personal

computers these days are equivalent to the supercomputers that NASA used

to have 10-15 years ago.  128 MEG RAM, Gigabytes of storage and

fast processing speeds.  All for $1,000.00 or thereabouts.  And you wonder 

why arabs and other people are buying kids computer toys to try

out their defense simulations.


     MCNP is a great US product.  If you have the time and money to use

it.  Good Luck.
