Monte Carlo simulation analysis of X-ray density logging shields
He jishuBackgroundThe use of controlled X-ray sources instead of 137Cs radioactive sources in density logging has become a new trend. The intensity of the X-ray source is substantially influenced by the high voltage on the target substrate, and the density ...

Probable solar flare doses encountered on an interplanetary mission as calculated by the MCFLARE code [PDF]
, 1971 The computer program, MCFLARE, uses Monte Carlo methods to simulate solar flare occurrences during an interplanetary space voyage. The total biological dose inside a shielded crew compartment due to the flares encountered during the voyage is determined.
