We have a
small source used in some engineering studies. The source is mounted on the
wall. We keep a dosimeter very close to it and read it on a regular basis for increases
over bg.

radioactive source
Same thing in Canada, no requirement to leak test a Kr-85 source.
Make sure that you assess the dose rate on a certain frequency if the source is
in permanent storage in order to detect a potential leak .

Could
anyone tell us how to do leak test of a radioactive Kr-85 source.
If you have a license for this source I believe that it will exempt the source
from leak testing. If it leaks it will no longer have any radiation
coming from the source. In general in the USA Kr-85 sources do not
have to be leak checked.
