Notes:  When a sealed source is contained (and normally stored) within a device (logging tool), the sealed source manufacturer and model number is shown below the entry.  When NRC has been able to determine that a sealed source model was manufactured/distributed by another company, or more than one model designation may have been used, this information is shown in parenthesis below the entry.  Neutron generators are shown by the designation "Nu Gen".  An asterisk (*) indicates that the source is used within the logging tool's electronics package.
