Question 227: (a) Must gauge licensees perform a survey
of each gauge package (if the package is labeled with a DOT
label) for contamination and radiation levels upon receipt
of the package? (b) What surveys must a licensee perform
during routine operation where portable gauges are
transported daily from site to site, then returned to a
storage location?
Answer: (a) As a result of amendments to Part 20
published on 8/31/92 [57 FR 39353], the licensee is not
required to survey the gauge package for contamination if
the source is in special form as defined in 10 CFR 71.4 and
is not required to monitor radiation levels unless the
package contains quantities of radioactive material that
are in excess of the Type A quantity, as defined in 10 CFR
71.4 and Appendix A to Part 71, provided there is not
evidence of degradation of package integrity.
(b) If there is no evidence of degradation of package
integrity, no surveys are required if the package contains
less than or equal to a Type A quantity and the source is
in special form. If the source is not in special form, a
contamination survey is required; if the source is greater
than a Type A quantity, the external surface of the package
must be monitored for radiation levels. (Reference: 10
CFR 20.1906, 71.4)
