The conversion ffrom intake to dose is essentially the same relationship The differences are in the parameters and these are: described for Fy Fo the gut traqgfer factor for 239+240py= 1974 and for Am = 5x1074 the fraction transferred across the gut that goes to bone = 0.45 for Pu and Am. the constant te conver’ Ri W bone marrow = 4.

This number is converted from Spiers conversion factor of 5000 g of mineral bone and alpha 16.9 rad which is based gn08 uCi-Y energies for = +240py and 241Am of 5.4 Mev and 5.6 Mev respectively. the term for the time integration over the exponential function representing the retention time of Pu and Am in bone with the parameters listed in the above text.
