Slotted Annular Source |
|
| This annular dummy
source, at least I assume that it is a dummy source, is 7/16" long
and 3/16" in diameter. A slot runs completely down one side.
Sources like this were usually loaded with Cs-137 and sometimes
Sr-90. The internal cavity would be so small that it could only hold
a fraction of a curie. Not many of these were made.
An XRF analysis reveals that the main constituents are iron and chromium. |
