AI Thread Summary
Neutron moisture meters using Am-241/Be sources are discussed, with inquiries about regular wipe and leak testing protocols. The U.S. NRC website offers resources on density gauges, including inspection documents. Users are seeking information on moisture levels in concrete floors and the effectiveness of calcium chloride tests for this purpose. Recommendations for testing methods and user experiences with calcium chloride tests are requested. The discussion emphasizes the importance of creating new threads for current inquiries rather than reviving old ones.

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...
 
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.
 

Thread 'Energy Spectrum Attenuation'

Hello, I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere...
