resuspension factors



Im looking for some input.

Jack:



Would you have knowledge of or know of an electronic reference that

could

provide me with resuspension factors for machining on a lathe - perhaps

surface grinding??



I am working on a lesson plan that will help the techs estimate the

amount

of radioactivity that could be available to become airborne if, for

example, fixed radioactivity was propelled into the air from a machining

operation.  I am using values of E-5 per meter to E-7 per meter.

There is an OE that discusses the machining of a valve stem that has a

stellite seat with fixed and loose contamination of 7.8E8 dpm/100 sq.cm.

Consider the airborne activity if you use a resuspension factor of E-5

per

meter.
