RE: Leak test of Kr-85 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.
