Hordtack resulting from combustion air intakes were within the dose
range estimated theoretically.°? It should be noted that accurate
estimates of ingress dose are still impossible.
References 33 and 66
represent the best available information, but even in these studies,
results could be presented only as a wide range of values due to
uncertainties, assumptions, and approximations in the ingrese-dose
estimates.
For underwater bursts at shallow or moderate depths, such as Shots
Umbrella and Wahoo, comparison of estimated ingress doses with total
doses at below-decks locations reveals that the doses due to ingress
of contaminant were in all cases secondary to the doses due to transit
radiation.
However, if shielding were provided to reduce the dose due
to exterior transit radiation, then radiation due to interior contamination from bursts such as these two could require consideration.
For deep underwater bursts, such as Wigwam, there was no detectable
contamination of ships traversing the path of the aerosol within 20 min
after burat.
