Background Information

The RLL device is distributed by Ronan as a General Licensed device. This data sheet details the advantages of the RLL device versus other generally licensed devices. Note that these devices do not require any site-specific license.

The RLL Series Systems utilize only microcuries of a radioisotope. Because these devices use such a low activity source the primary responsibilities of the user are reduced to those of protection against theft and accountability for the materials.

Wipe testing, radiation surveys and special radiation training typically required for most Licensed devices are not required. When the device is no longer in use, it should be returned to Ronan or a licensed waste broker for disposal.

"RLL" Device Advantages .vs. General Licensed Devices

Commonly, General License is viewed as the simplest form of Licensing. However, even with these devices wipe tests, shutter checks, surveys etc., are required to be performed at certain intervals.

The RLL Devices using the low energy source quantities are not subject to the following requirements:

• Low Energy Source-(900 µCi of Cesium-137)
• No wipe testing
• No radiation surveys required
• No on/off shutters on source holders are required due to low radiation fields
• Able to install, relocate, and move the devices without a licensed person present
• Safest gamma gauge on the market

Summary

The regulations pertaining to the RLL series of devices are not as restrictive as most devices distributed as General License. However, they must be used in accordance with instructions from Ronan, protected from theft or loss and disposed of properly. Theft or loss must be reported to the NRC or agreement states.
