Skyshine from Burial Vaults

[Nathan, Steve]

We have recently completed design studies for an underground  vault for low activity (0.1 -0.4 Ci/gallon) Cs-137 waste.  The results indicate significant dose rates at large distance from the vault due to skyshine.  Our customer has asked if we can provide benchmarks for the calculational methodology (MCNP 4C Monte carol analysis) before they undertake installation of a thick roof on the vault.



Does anyone have any empirical or analytic data that we could use to benchmark our calculations.
