SUMMARY

The discussion centers on the use of neutron moisture meters, specifically those utilizing Am-241/Be sources for soil moisture measurement. Participants inquire about protocols for regular wipe testing and leak testing to ensure safety and compliance. Chris references the U.S. NRC website as a resource for guidelines on density gauges, including inspections and events related to their use. Additionally, there is interest in alternative moisture testing methods, such as the calcium chloride test, for assessing moisture levels in concrete floors.

PREREQUISITES
  • Understanding of neutron moisture meter technology and its applications
  • Familiarity with Am-241/Be radioactive sources and safety protocols
  • Knowledge of moisture testing methods, including calcium chloride tests
  • Awareness of regulatory guidelines from the U.S. NRC regarding density gauges
NEXT STEPS
  • Research U.S. NRC guidelines on density gauges and their inspection protocols
  • Explore the operational principles and safety measures of neutron moisture meters
  • Investigate the methodology and accuracy of calcium chloride moisture testing
  • Learn about best practices for conducting regular wipe and leak tests on moisture meters
USEFUL FOR

This discussion is beneficial for environmental scientists, construction professionals, and safety officers involved in moisture measurement and testing, particularly those utilizing neutron moisture meters and other moisture assessment techniques.

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.

Engineering news on Phys.org
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...
 
I have had this question for a while now and have yet to find a reply. I'm interested in finding out how much moisture is going through a concrete floor that is on the end of my home. So my question is, where can I get a test? I did a little research and discovered a place that has a calcium chloride test but I would like a review if anyone has used it, and also I would like to know how to use it!
Thank you for any reply.
 
Just for the future, please don't reply in threads that are several years old. Starting a new one and linking to this one would be more acceptable.
