The most common use of radioactive material in construction and engineering is with portable radiation devices (also called nuclear gauges or densitometers). These devices are used to measure the density and moisture of compaction materials. To acquire and use these devices, organizations must first have a nuclear substances and radiation devices (NSRD) licence from the Canadian Nuclear Safety Commission (CNSC). Maintaining a NSRD licence requires a radiation safety program.
