Portable Nuclear Moisture and Density Gauges Used in the Construction Industry

Dale Wuokko, P.E.

This course provides information on the safe handling and use of portable nuclear moisture and density gauges commonly used in the construction industry. It also discusses inspection programs to support proper use, storage, and maintenance of these gauges and examples of adverse incidents involving these gauges which could have been prevented. Portable nuclear gauges provide a highly reliable and accurate method of measuring the moisture and density of a material, such as soil, asphalt and concrete. Portable nuclear gauges all use essentially the same design and basic approach to determine these measurements.

This course information does not replace userís training programs, but rather supplements these programs, the operating manual, and the specific regulatory license information issued by the U.S. Nuclear Regulatory Commission (NRC) or Agreement State for the specific portable nuclear gauge. The gauge user is required to be knowledgeable of and implement the specific license requirements and the applicable NRC or Agreement State requirements.

Portable nuclear gauges are tools that like a welding machine or power saw can be hazardous unless proper safety precautions are taken. However, the potential hazard from the radiation source contained within a portable nuclear gauge is not as obvious to the naked eye as a welding flame or saw blade. Nonetheless, by implementing proper safety precautions working with and around portable nuclear gauges, they will not pose a threat to health or safety.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
