Radiological Surveys and Data Trending - Continued

DOE-STD-1128-98

Guide of Good Practices for Occupational Radiological Protection in Plutonium Facilities

Records that establish the conditions under which individuals were exposed to

external radiation (such as facility radiological conditions records generated by the

monitoring programs) should be retained to provide a chronological and historical

record. See ANSI/HPS-N13.6 (ANSI, 1999a).

A sufficient number of points should be surveyed in order to adequately assess the

radiological status of the area. Regular predetermined points may be used, but

additional spot monitoring should be done to ensure that all changes in dose rates

are identified, recorded, and reviewed.

All records of surveys should clearly identify, as a minimum:

The name, signature, and employee number of the surveyor.

survey instrument(s) model number, serial number, and calibration date.

the type(s) of radiation being monitored (e.g., neutron, gamma, etc.).

the dose rates.

the date and time the survey was performed.

locations where radioactive material is located temporarily (or is being

temporarily stored) or where equipment that generates ionizing radiation is

being operated.

Records of the results of radiation surveys should be retained in accordance with

facility policy.

Survey data should be reviewed by supervisory personnel. Significant findings

should be presented to the facility manager in a timely manner.

Health physics personnel should summarize survey data in each building or area at

least once a quarter. Significant changes or trends in area dose rates and/or

radiological contamination should be noted and corrective actions assigned. The

survey summary should be presented to the facility management quarterly.

Survey results and data summaries should be made available to the ALARA team

chair periodically and should be used:
