APPENDIX F

RELEASE OF POTENTIALLY CONTAMINATED MATERIAL - DOE ORDER 5400.5

Instructor's Notes

1.0 Surface Contamination Levels

Prior to being released, property should be surveyed to

determine whether both removable and total surface

contamination (including contamination present on and

under any coating) is greater than the levels given in the

DOE Order 5400.5.

2.0 Potential For Contamination

Property should be considered to be potentially

contaminated if it has been used or stored in radiological

areas that could contain unconfined radioactive material or

that are exposed to beams of particles capable of causing

activation.

Material and Equipment in Radiological Areas established

to control surface or airborne radioactive material shall be

treated as potentially contaminated.

3.0 Inaccessible Areas

Where potentially contaminated surfaces are not accessible

for measurement, such property may be released after case-

by-case evaluation and documentation based on both the

history of its use and available measurements demonstrate

that the unsurveyable surfaces are likely to be within the

release criteria.
