Radiological Surveys and Data Trending cont'd

DOE-STD-1136-2004

Guide of Good Practices for Occupational Radiological Protection in Uranium Facilities

name, signature, and employee number of the surveyor,

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

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

dose rates,

estimated doses to surveyors (from direct-reading dosimeters, if applicable),

date and time the survey was performed, and

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 the facility radiological control supervisor. Significant findings

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

summarize survey data in each building or area at least once a month. 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 monthly.

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

periodically and should be used to:

provide a basis for evaluating potential worker exposure on a job and in ALARA

preplanning,

provide a baseline for trend analysis, investigation, and correction of unusual conditions,

track the status of jobs (including identification of good practices) and detect departures

from good operating procedures and/or the failure of radiation controls, and

identify the origin of radiation exposures in the plant by location, system, or component.

Radiological control personnel should post survey maps at the entrance to all radiological areas so

personnel can be aware of radiological conditions within the area.

A survey data trending program should be conducted to indicate the continuing effectiveness of

existing control, to warn of deterioration of control equipment or effectiveness of operating procedures, to

show long-term variations in radiation levels, and to identify and correct improper radiation work

practices. See NUREG-0761, Radiation Protection Plans for Nuclear Power Reactor Licensees (NRC

1981), sections 07.B(I)(C), 09.B(4), and 09.C(I)(C).

Radiological control personnel should perform trend analyses on all permanent radiological areas.

At a minimum, one complete survey record should be evaluated and included in the trend analysis program

for each survey required to be performed by the facility routine control program. See NUREG-0761 (NRC

1981), 07.B(I)(C), 09.B(4), and 09.C(I)(C).
