Reporting and Documenting Contamination Levels

DOE-STD-1128-98

The use of vacuum cleaners for contamination control requires careful

consideration and strict controls to assure that the process does not spread

contamination. As a minimum, all vacuums used for radioactive material

should have HEPA filtration on the exhaust. In some instances, the additional

precaution of having the exhaust vented into a process ventilation system

should be considered.

4.2.2 Reporting and Documenting Contamination Levels

Radiological control programs require the performance of contamination surveys to

determine existing conditions in a given location. Maps with sufficient detail to

permit identification of original survey locations should be maintained. Records

should contain sufficient detail to be meaningful even after the originator is no longer

available. Contamination surveys should be recorded on appropriate standard forms

and include the following common elements:

-- Date, time, and purpose of the survey

-- General and specific location of the survey

-- Name and signature of the surveyor and analyst

-- Pertinent information needed to interpret the survey results

-- Reference to a specific Radiological Work Permit if the survey is performed to

support the permit [see DOE standard, Radiological Control, Ch. 1. part 751.1

(DOE, 2004)].

Records should be maintained to document changes in monitoring equipment,

techniques and procedures [see DOE standard Radiological Control, Ch. 1. part 751.2

(DOE, 2004)].

In addition, records of contamination surveys should include, at a minimum, the

following information:
