The transfer coefficient appears to be the fraction of the trace element not recovered from the

test apparatus after the run. Others have experienced difficulties with recovering/detecting

various elements in the residues from the combustion of TBP-kerosine solvents. The

decontamination factor is the fraction of airborne material carried to the collection filters,

although it appears that only the initial airborne concentration was used for the estimates.

The actual concentration may have varied during the run. The ARFs reported from other

studies are generally the fraction of the material used in the experiment that is carried to the

collection filters that are within a few feet and the exhaust gases relatively contained from the

point of origin to the collector. The fraction reaching filter is the transfer coefficient

multiplied by the reciprocal of the decontamination factor. Thus, ARFs reported from other

studies should be smaller than the transfer coefficient but greater than the fraction reaching

filter. The values are within an order of magnitude or two for the cesium and cerium used

for the small scale and large scale experiments and are considered to corroborate those

values.
