PRIVACY ACT MATERIAL REMOVED data for these cascade impactors in terms of aerodynamic diameter. ww Calculations of diameters from the Casella cascade impactor data. -& in As shown on the next viewgraph (LRA-25), this represents our current of the problems again with this data, only ones that data. 25 26 27 28 is that these three points are the are valid where this cascade impactor was actually sizing If we extrapolate this line ‘way up here someplace to get to the 50 percent level, we cascade impactor was extrapolation, 10 11 12 13 14 r5 16 17 18 19 20 21 22 23 24 Now one we are extrapolating actually calculate well sizing. very beyond That's large the range because, aerodynamic if where this we do this diameters, so this presents somewhat of a problem in terms of how do we use this data? These diameters, of course, are way too large to enter the lung dynamics model of the ICRP; apart. so we have chosen to avoid that problem by taking this data We treat it as though it were five individual samples, and then we use the data with an associated particle size for each one of these stages, plus the backup filter in the individual front end of this thing, so that we have broken it apart basically into five different samples. The next inhalation viewgraph (LRA-26). calculations from the We last have time significantly they were presented, sense that before we only made these calculations prepared for this case / order for completeness, have added difference all in of sex. testes for males. changed for the lung. in our the As we litigation), we felt that we must, in do these calculations for the other organs; so we these other organs. We calculate for ovaries The and semicolon uterus for represents females a and So that we have done those calculations for those organs; and in order to make sure that we had the appropriate radionuclides for all of these additional organs, we did add several new radionuclides: Strontium to look at bone marrow dose, and mainly these, to make sure that we had the refractory elements that might be of some interest in terms of 40
