In summary, the conversation discusses the use of neutron moisture meters and the process of regular wipe testing and leak testing. The U.S. NRC website has publicly available documents on this topic, and there is a discussion on finding a test for moisture in a concrete floor. The user also requests for any reviews or information on how to use a calcium chloride test. Lastly, a reminder is given to not reply in old threads and to start a new one instead.

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.

, neutron moisture meters are commonly used by scientists, engineers, and agricultural professionals to measure the moisture content of soil and other materials. These meters use a small amount of radioactive material, typically Am-241/Be, to emit neutrons into the ground. These neutrons interact with the hydrogen atoms in the soil, and the resulting radiation is measured to determine the moisture content.

In the PF-land community, it is possible that some individuals or organizations may use neutron moisture meters for various purposes, such as environmental monitoring or construction projects. However, it is important to note that the use of radioactive materials in these meters is heavily regulated and requires proper training and licensing.

In terms of regular wipe testing and leak testing, it is crucial for those using neutron moisture meters to follow strict protocols and guidelines to ensure safety and prevent contamination. This includes regular wipe testing to check for any potential contamination on the equipment and surrounding areas, as well as leak testing to ensure the integrity of the meter's shielding.

In the rare case of a positive wipe test result for contamination, it is important to follow proper procedures for decontamination and reporting to the appropriate authorities. It is also essential to have a thorough understanding of safety protocols and to always handle these meters with caution to prevent any potential risks.

Overall, the use of neutron moisture meters is a valuable tool for many industries, but it is important to prioritize safety and follow proper procedures to prevent any potential risks or contamination.
 

1. Who uses neutron moisture meters?

Neutron moisture meters are commonly used by farmers, soil scientists, and construction professionals to measure water content in soil, crops, and building materials.

2. How do neutron moisture meters work?

Neutron moisture meters work by emitting neutrons into the material being measured. These neutrons interact with the hydrogen atoms in the material, and the resulting energy is measured to determine the water content.

3. What are the advantages of using neutron moisture meters?

Neutron moisture meters provide non-destructive and accurate measurements of water content, and can be used in a wide range of materials and environments. They are also portable and easy to use.

4. Are there any limitations to using neutron moisture meters?

Neutron moisture meters may not be suitable for measuring water content in materials with high levels of hydrogen or in areas with high levels of natural radiation. They also require proper calibration and training for accurate results.

5. How do I choose the right neutron moisture meter for my needs?

The right neutron moisture meter will depend on the type of material and environment being measured, as well as the desired level of accuracy. It is important to consult with a professional and carefully consider the specific needs before purchasing a neutron moisture meter.
