Human Performance Evaluation of Industrial Radiography Exposure Events
The Nuclear Material Events Database (NMED) is maintained by the Office for Analysis and Evaluation of Operational Data (AEOD) under contract with the Idaho National Engineering Laboratory (INEL) and includes radiation exposure events reported by both the U.S. Nuclear Regulatory Commission and Agreement State licensees. A review of the data in NMED shows that industrial radiography overexposures account for a significant number of overexposures reported to NRC and that most of the acute exposures have resulted in physical injury. The number of reported radiography licensee overexposures is especially significant when considering that radiography licensees account for less than 10 percent of NRC and Agreement State licensees.
To develop better information on: (1) the cause of radiography overexposures, and (2) how to minimize radiography overexposures, AEOD contracted with INEL to review the NMED data and perform a human factors review of field radiography overexposure events reported between 1987 and 1994. The scope of the effort included a review and analysis of historical and current events, categorization of the events in terms of human actions and contributing factors, and detailed modeling of a subset of 19 events. INEL-95/0387, "Human Performance Evaluation of Industrial Radiography Exposure Events," summarizes the methods, results, and conclusions drawn from the human performance evaluation. Data summaries and analysis materials are included in the appendices of this report.
In the initial analysis of the 95 events, one third were categorized as involving procedural errors (e.g., improper survey or survey not performed, camera not locked); one third were events involving equipment problems (e.g., equipment design issues, source connections/disconnections); and another third involved external factors (e.g., alarms, supervision, and area control). The data showed that there was a greater incidence of events for more recent time periods (1993-94), but this apparent rise could be caused by changes in reporting practices and more rigorous data collection efforts.
The results of the initial analysis were supported by detailed modeling of a subset of 19 acute overexposure and acute-but-less-than overexposure events, based on regulatory limits on personnel exposures. A modeling method was developed and applied to use the information on overexposures to help describe how human performance and equipment interactions were affecting industrial radiography operations. Procedural errors were involved with sixty-eight percent of the 19 events modeled. Of these, nearly half concerned failure to survey. The most common performance errors occurred in the setting up of equipment before the radiograph and in the use of survey meters throughout the process.
The report also includes suggestions related to training, equipment inspection, and equipment design, as well as a data collection guide to assist incident investigators in collecting human performance data.
Additional information about the study and copies of the INEL report can be obtained from Samuel L. Pettijohn, AEOD, at 301-415-6822.

Training and Monitoring of Carrier Personnel: Comments on NRC Generic Letter 95-09
The U.S. Nuclear Regulatory Commission's licensees are responsible for implementing NRC regulations and license conditions, including training and radiation monitoring requirements, for persons who enter their facilities, whether these persons are employed by licensees or by different organizations. When applied to persons who enter many licensed facilities in the course of their work, some of these requirements, --particularly the training and monitoring requirements,-- may prove burdensome. For example, carrier and shipping personnel may enter a large number of licensed facilities to pick up or deliver packages. Implementing the training and monitoring regulations for these persons would mean that many of the facilities visited by these personnel would have to provide training and radiation monitoring, in addition to the training and monitoring their employers, the carriers or shipping companies, usually provide. Such multiple training and monitoring would be mostly redundant, would not improve safety, and would burden both the NRC licensees and the carriers or shipping companies.
To try to relieve this burden, NRC issued, on November 3, 1995, Generic Letter 95-09, "Monitoring and Training of Shippers and Carriers of Radioactive Materials." The generic letter stated that NRC licensees need not provide the required training and monitoring to carrier and shipping personnel who enter their facilities, provided they were being trained and monitored under acceptable programs offered by the personnel's carriers or shipping companies. The generic letter stated that acceptable programs would include programs such as those established under Department of Transportation regulations, or other programs that, after evaluation by the licensees, are deemed to provide training and monitoring equivalent to those required under NRC regulations.
Soon after Generic Letter 95-09 was issued, NRC received complaints that some carriers and shippers were being inundated by requests from NRC licensees for letters stating that their personnel had received the appropriate training and are being appropriately monitored. NRC also received numerous telephone calls from licensees asking whether the guidance in the generic letter applied to their facilities. This response was unexpected, because NRC knew that the generic letter would be relevant to only a very small number of its licensees. Analysis of the questions and requests received from licensees showed that this unexpected response stemmed almost entirely from licensees being unaware of the most recent changes in NRC regulations affecting training. This article attempts to clarify this issue.
Up until August 14, 1995, 10 CFR 19.12 required that all persons entering a licensee's restricted area be provided with training on radiation protection and the hazards of radiation exposure. This meant that any person working for a carrier or shipping company who entered the licensee's restricted area to pick up or deliver a package had to be trained by the licensee. This rule has been changed, however, and as of August 14, 1995, the new rule states that training must be provided only to those who are occupationally exposed, and then only if the person is likely to receive, in a year, an occupational dose in excess of 1 mSv (100 mrem). In the vast majority of cases, carrier and shipping personnel who enter a licensee's facility receive, in a year, a dose in that facility that is far less than 1 mSv (100 mrem), and therefore training is not required to be provided to these personnel by the licensee. Only in the rare situation in which the carrier person is likely to receive a dose in excess of 1 mSv (100 mrem) in a year, at a specific licensee's facility, is that licensee responsible for ensuring that training is provided.

The Timeliness Rule May Apply to Onsite Burials
The U.S. Nuclear Regulatory Commission staff is developing guidance considering the application of the Timeliness Rule (59 FR 36026) to onsite burials of radioactive material. Sections 30.36, 40.42, 70.38, and 70.54 of the rule state that if a site contains buildings or outdoor areas that contain residual radioactivity and have not been in use for 24 months, the licensee is required to notify NRC of this situation. Within 12 months of this notification, the licensee is required to begin decommissioning, or submit a decommissioning plan for these areas if they are not suitable for release in accordance with NRC requirements.
If onsite burials are considered part of outdoor areas, this rule could include those areas that were used by licensees to dispose of radioactive materials in accordance with 10 CFR 20.304 (rescinded) and 20.302 (now Section 20.2002). If the Commission determines that the rule does apply to onsite burials, the licensees could be required to determine if the burial sites would be suitable for release under NRC requirements. This could require the licensee to characterize the burials, and submit decommissioning plans for the sites as early as August 1996. This effort could include both current and terminated licenses, as well as operational and decommissioning sites.
The staff is currently consulting with the Commission on this issue and plans to distribute a Generic Letter to the licensees describing the Commission's decision and outlining necessary future actions.

Business Process Re-engineering Update
The staff's Business Process Re-engineering initiative, which is designed to enhance the overall quality of licensing reviews and associated tasks, has engaged in a set of activities designed to provide licensees, Agreement States, and members of the public the opportunity to provide feedback on the new process.
On April 25, 1996, the office of Nuclear Material Safety and Safeguards (NMSS) held a public workshop to obtain suggestions and comments on the U.S. Nuclear Regulatory Commission's Business Process Redesign (BPR) of the materials licensing process.
To publicize the workshop, the staff published a Federal Register notice on March 6, 1996, and mailed a letter announcing the meeting and the agenda to each of NRC's materials licensees.
The attendees provided highly useful comments on the BPR process, as well as very specific comments on the development of the Materials Electronic Library. The licensees recommended that additional workshops be held at different locations throughout the country. They also recommended that licensees participate in some type of pilot project or Beta test before full implementation of the licensing process.
In April 1996, the staff published two NUREGs describing NRC's methodology for redesigning its processes: NUREG No. 1539, "Methodology and Findings of the NRC's Materials Licensing Process Redesign," and NUREG No.1541, "Process and Design for Consolidating and Updating Materials Licensing Guidance."

Reports of Atypical Radiation Levels Surrounding Packages Containing Technetium-99M/Molybdenum-99 Generators
U.S. Nuclear Regulatory Commission regulations establish the maximum allowable radiation levels on the external surfaces of packages containing licensed material. Section 71.47(a) states, in part, that each package of radioactive materials offered for transportation must be designed and prepared for shipment so that under conditions normally incident to transportation, the radiation level does not exceed 2 mSv/hour (200 mrem/hour) at any point on the external surface of the package. Region I has recently had several reports, from licensees receiving packages containing Technetium-99m/Molybdenum-99 generators, of radiation levels exceeding 2 mSv/hour (200 mrem/hour) on the external surfaces. Investigations into these reports have revealed that the increased radiation levels have resulted from a variety of factors and have failed to identify any common elements that caused these survey findings.
NRC reminds licensees of the importance of performing surveys of incoming packages that contain radioactive materials. In addition, 10 CFR 20.1906(d) requires, in part, that licensees immediately notify the appropriate NRC regional office when external radiation levels exceed 2 mSv/hour (200 mrem/hour) at any point on the external surface of the package. NRC regional offices would be interested in information on unusual radiation levels.
It would be useful if NRC regional offices were notified of cases in which generators show unusual radiation levels, even when these levels are not high enough to require reporting under 10 CFR 20.1906(d), so that NRC can gather additional information, if necessary, and possibly identify common problems with packages containing generators.
