Article 751 - Requirements

1. Radiological Control Programs require the performance of radiation, airborne radioactivity and contamination surveys to determine existing conditions in a given location. Maps with sufficient detail to permit identification of original survey and sampling locations should be maintained. Records shall contain sufficient detail to be meaningful even after the originator is no longer available. Radiological surveys should be recorded on appropriate standard forms and include the following common elements:

2. Date, time and purpose of the survey

3. General and specific location of the survey

4. Name and signature of the surveyor and analyst

5. Pertinent information needed to interpret the survey results

6. Reference to a specific Radiological Work Permit if the survey is performed to support the permit.

• Records shall be maintained to document changes in monitoring equipment, techniques, and procedures. Return to Chapter 7, Part 5 Table of Contents

Article 752 - Radiation Surveys

1. In addition to the elements provided in Article 751, records of radiation surveys shall include, at a minimum, the following information:

2. Instrument model and serial number

3. Results of the measurements of area dose rates

Article 753 - irborne Radioactivity

1. In addition to the elements provided in Article 751, records of airborne radioactivity shall include, at a minimum, the following information:

2. Model and serial numbers of the sampler and laboratory counting instrument when available or unique identifier of each sampler and instrument.

3. Location of fixed air samplers

4. Location of portable air samplers used for a survey

5. Air concentrations in general airborne areas and breathing zones

6. Supporting parameters, including collection efficiency, flow rate, duration of sampling, correction factors and filter medium.

Article 754 - Contamination Surveys

1. In addition to the elements required by Article 751, records of contamination surveys shall include, at a minimum, the following information:

2. Model and serial number of counting equipment

3. Contamination levels (using appropriate units) and appropriate supporting parameters including counting efficiency, counting time, correction factors, type of radiation and whether the contamination was fixed or removable

4. Location of areas found to contain hot particles or high concentrations of localized contamination

5. Follow-up survey results for decontamination processes cross-referenced to the original survey.
