Incidents Regarding Portable Nuclear Moisture and Density Gauges

Dale Wuokko, P.E.

This course discusses incidents regarding the use, transportation, and storage of portable nuclear moisture and density gauges commonly used in the construction industry. Portable nuclear gauges provide a highly reliable and accurate method of measuring the moisture and density of a material. For example, portable nuclear gauges are used to measure parameters such as the moisture in soil and the density in asphalt in a paving mix.

Portable nuclear moisture and density gauges contain small amounts of radioactive material and are therefore regulated by the U.S. Nuclear Regulatory Commission (NRC) or as-delegated to an Agreement State. Portable nuclear moisture and density gauge users are required to be knowledgeable of and implement the specific regulatory license requirements and the applicable NRC or Agreement State requirements. Nonetheless, industry incidents continue to occur where these requirements are not met, resulting in the regulatory authority citing the involved party for violations, and in some cases, monetary civil penalties. These incidents can be utilized as a source of lessons-learned to prevent similar incidents from occurring within the industry.

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