Is the eye applicator an instrument? You should be able to ship it
"Excepted package-instruments or articles" 10-2 A2 value or "Excepted
package- limited quantity of material" 10 -3 A2 value and the package is
below .5 mr/hr contact on all six sides. Then fill out the exception
statement place it in or on the package. Mark the item or the package
radioactive and ship.  

If you can take a reading of the source you can use the 6CEN formula to
estimate the Curie amount.  C = D/E
