Abstract Studies were conducted under controlled conditions in order
to observe the resulting survival patterns in solid crabmeat of
Salmonella typhosa, Salmonella paratyphi B, and SaImonella wichita
following individual exposure to various doses of gamma radiation.
As shown in their survival curves, these species of Salmonella
exhibited in varying degrees a rapid non-linear decline in viability
with respect to the radiation doses. This decline tended to become
very gradual as the radiation dose increased, showing a
distinct tailing of small numbers of survivors over a number of
increasing doses at. the end of the dose-survival curve. This
phenomenon was referred to as the "tailing effect".
The above species of Salmonella were further subjected individually
to gamma radiation in various dilutions of crabmeat.
The results revealed that the "tailing effect" gradually disappeared
as the concentration of the crabmeat decreased with the
dose-survival curve tending to become linear.
