Radiometric responsibility from start to finish

The digital age has not been kind to the paper industry. Demand for paperwork like order forms, invoices, contracts, and more have dropped since that work can be done digitally. Nowadays, most of these things are filled out and signed online, and the receipts are just e-mailed to us. The need for physical paper just isn’t as high as it used to be. As a result, paper mills across the country slowed down production or shut down all together. It’s just the nature of the constantly evolving way people do business.

Change, however, never stops, and demand for paper is on the rise again. More people shopping online means more items getting shipped, and those things arrive at our doorstep in brown cardboard boxes. Now, paper mills that were once thought to have closed their doors forever are being purchased and placed back into operation, breathing new life into the industry and the communities where they’re located. A Kentucky paper mill recently experienced this rebirth, but it wasn’t as easy unlocking the doors and turning the power back on.

Only a couple years ago, a major paper company made the difficult decision to shut down one of its paper mills. With the paper mill closing its doors, it had to remove any radiometric sources used for measurements. The United States Nuclear Regulatory Commission, or NRC, requires companies monitor and label any radioactive material, so by law, the paper mill couldn’t just leave everything behind. They needed a way to safely and legally remove the sources.

This particular plant had more than two dozen different radiometric sources from four different suppliers. Fortunately, one of those suppliers was VEGA, a company that prides itself on being a complete radiometric measurement solutions provider. Like all other radiometric measurement organizations, VEGA supplies radiometric sources, but they also offer their ReSource® Program, which retakes ownership of radioactive sources used in industrial measurement systems. These sources are then reused, recycled, or properly disposed of.

Reusing and recycling functioning sources minimizes the amount of radioactive materials being introduced into the environment. Radioactive sources are used in difficult applications where other measurement solutions fail to work, so managing these all-important sources throughout their lifecycle is critical. VEGA was able to enter the recently closed paper mill, safely remove and take ownership of all the radiometric sources, and leave the paper mill in compliance with the NRC.

Roughly two years later, a new company purchased the Kentucky paper mill to meet the increasing paper demands for consumers’ changing habits. To get the operation up and running, they needed instrumentation for roughly a dozen key pipe density measurements. These pipes ranged in size anywhere between two inches up to 22 inches, and all of them still had the old detectors from different manufacturers.

Different manufacturers of radiometric instrumentation all have different philosophies on how measurements should be made. This means the size or type of source can vary from manufacturer to manufacturer. This left the new paper mill owners with a decision to make: go back to the different manufacturers for sources and recalibration, find a single source provider and recalibrate all the detectors, or purchase new detectors with the right size and type of source needed from a single manufacturer to ensure accurate and reliable measurements in every application.

The new owners ultimately decided to work with VEGA to purchase new low-strength sources and new detectors. By purchasing everything new, the paper mill didn’t have to worry about any older detectors no longer working after two years of not being used, and all the sources could be the same size and type. By choosing VEGA, they had the peace of mind knowing VEGA has experience with radiometric technology for every step of the way.

VEGA has been developing, manufacturing, and improving radiometric measurement technology since 1955. Their extensive experience helps customers like this paper mill in Kentucky throughout the life of the measurement sensor. From the start, VEGA helps customers choose the right measurement solution and get the appropriate licensing through the necessary government agencies. They provide the proper training and maintenance needed throughout the life of the sensor, and finally, VEGA is there when a radiometric source is no longer needed.
