NON-CONTACT MEASUREMENTS USING NEW, PROVEN RLL SERIES GAMMA RADIATION DEVICES

In the past fifty years, most radiation gages used for industrial applications requiring non-contact density, level or weighing measurements have always used relatively small quantities of radioactive material (10 - 100mCi). The Ronan RLL device, however, uses source activities that are generally 100 times less than what has been the norm. Lower source activities provide for gages that are obviously safer and easier to shield. But more important, because the source activity is low, they are exempted from a lot of the regulations which apply to most radiation devices on the market.

The RLL devices are distributed by Ronan as General Licensed devices.

Possession and use of Generally Licensed Devices is regulated or licensed by the United States Nuclear Regulatory Commission (NRC) per the statutes of Title 10 CFR Part 31.5. General Licensees do not have to obtain a specific license, nor are they subject to submit any forms or applications, but are still subject to conform to the general license regulations for that device. The information pertaining to the regulations is found on the labeling of the device and supplied in the Ronan manual shipped with the device.

Unlike other General Licensed Devices, the Ronan RLL Devices do not require wipe testing, on-off shutter checks and radiation surveys by the user. Furthermore, no RSO, radiation training or factory assistance is required to install and use these devices safely, as long as the user instructions supplied by Ronan are properly followed. When the RLL Devices are no longer in service, they should be returned to Ronan or a licensed waste broker for disposal.

To summarize, the Ronan RLL Series devices are the safest gamma ray devices on the market. Because they use only the very lowest activity sources of Cs-137 and/or Co-60, they are exempted from wipe testing and radiation surveys by the user. In addition, the user can install, relocate and use the devices without a licensed person present.

All RLL Series devices are registered and approved by the State of Kentucky, an Agreement State for distribution by the Ronan Engineering Company.
