CONTAMiNATION SURVEY OFMATERIALS, EQUIPMENT, AND PORTABLE FACILITIES TO BE
RELEASED FOR CONTROLLED OR UNCONTROLLED USE (DPSOL 193-507) (Rev. 3, 1/22/90)
This procedure includes instructions for performing and documenting radioactive contamination
surveys on materials, equipment, and portable facilities to be released for controlled or uncontrolled use.
It provides guidelines on packaging, cleaning, and tagging material, equipment, and facilities for transport
The procedure describes guidelines, criteria, instrumentation, and documentation required to perform
a material, equipment, and facilities contamination survey for a conditional or unconditional release but
does not cover: materials having radioactivity dispersed within, materials made radioactive by neutron
irradiation, contaminated soils, or contaminated clothing and people.
The procedure refers to DPSOP 40 (Radiation and Contamination Control), DPSOP 170 (Interarea
Shipments), DPSOL 292-608 (Control of Measuring and Test Equipment), DPSOL 193-107 (Documenting
Radiation Surveys), and DOE Order 5480.11 (Radioactive Waste Management).
Instrumentation required includes portable survey instruments (Thyac with an HPO-210 probe or
equivalent), portable alpha instrument (Ludlum or equivalent), and smear count system (such as M&TE
All materials, equipment, and facilities are surveyed for unconditional or conditional release status if
they are stored or used in contamination, high contamination, or airborne radioactivity areas. HPO has the
authority to make the survey requirement include all material, equipment, and facilities stored or used
within an RCA.
Conditional/unconditional release criteria are:
" Beta-gamma contamination survey-no detectable contamination above background. Normal
detection efficiency for beta-gamma instrument is 15%, corresponding to 14,000 dpm/100 cm2
for small area contamination.
" Alpha contamination survey-no detectable alpha contamination. Normal detection efficiency
for alpha instrumentation is 50%, corresponding to 1000 dpm/100 cm2 for small area
" Smear survey-materials, equipment, and facilities smeared with a 100-cm2 smear are not
considered to have removable contamination if a measurement by a scaler is <10 dpm alpha,
<80 dpm beta-gamma, <150 dpm tritium (each above background of scaler).
The procedure further describes tagging guidelines for use of green (unconditional), black and white
(conditional), and yellow/magenta (radiation) tags. Also described in the procedure are documentation
requirements for release of materials, equipment, and facilities, including the Radiation Survey Logsheet
(OSR 4-17), which must include complete results of surveys.
