Who uses neutron moisture meters?

[ChrisLeslie]

Does anybody in PF-land use neutron moisture meters - the ones with Am-241/Be sources that probe into holes in the ground? If so, do you have a regime for regular wipe testing and leak testing? I am interested to find out if there are any cases of a wipe test result that showed contamination.

the U.S. NRC website has publicly available documents which address this. use the basic search function on their site for "density gauge" and check out the inspections and events links...
