Radiological Surveys and Data Trending cont'd

DOE-STD-1128-98

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:
