Information Notice No. 87-55: PORTABLE MOISTURE/DENSITY GAUGES: RECENT
INCIDENTS OF PORTABLE GAUGES BEING STOLEN
OR LOST
[Refer also to Information Notice No. 86-67, August 15, 1986, Same
subject]
Addressees:
All NRC licensees authorized to possess portable gauges.
Purpose:
This notice is intended to inform licensees of the recent increase in
incidents of portable gauges being lost or stolen during use, transportation,
and storage. It is expected that recipients will review the information for
applicability to their licensed activities and consider actions, if
appropriate, to preclude similar problems from occurring at their facilities.
However, suggestions contained in this information notice do not constitute
NRC requirements; therefore, no specific action or written response is
required.
Description of Circumstances:
Several incidents have occurred recently where portable moisture and density
gauges have been lost or stolen from licensees, either from job sites or from
vehicles during transportation. Gauges lost or stolen were not secured or
were stolen while left unattended by the users.
In one recent event, a gauge was stolen after the user failed to lock the case
and failed to chain the case to the truck, which itself was left unattended.
This event resulted in four violations of NRC requirements. In another case,
a gauge was stolen after being left outdoors, unattended, over a weekend, at a
construction site.
Discussion:
A primary contributing factor in these incidents was the failure of the gauge
users to secure and maintain control over the gauges.
Title 10 CFR 20.207 requires that licensed material (e.g., portable gauges)
must be under the constant surveillance and immediate control of the licensee,
or must be secured in storage. At construction sites, the licensee must
constantly control access to the gauge during use at the site, and keep it in
locked storage when not in use.

NRC licensees transporting portable gauges are subject to the regulations in
10 CFR Part 71. Section 71.5(a) incorporates certain regulations (49 CFR
170-189) of the Department of Transportation (DOT), to which these licensees
are also subject. Licensees who transport gauges to and from temporary job
sites in private vehicles are shippers acting as private carriers, and as
such, must comply with the DOT regulations governing both shippers and
carriers. Title 49 CFR 177.842(d) requires that packages containing
radioactive material (i.e., the gauge in its case) must be blocked and braced
to prevent movement of the package during transportation (see Information
Notice 87-31, attached). For pickup trucks, this requirement is usually met
when the gauge is secured within its case, and the case is secured and locked
to the bed of the truck.
The NRC has also noted several incidents where gauges were damaged in
transportation accidents or by being run over by construction vehicles. The
most prevalent cause of such incidents is the failure by the licensee to
secure and lock the cargo door, combined with a failure to properly secure the
device/case to the bed of the vehicle. Licensees are reminded that they
should use care to avoid these types of incidents. If a gauge is damaged, the
area around the gauge should be restricted, and the licensee's radiation
safety officer and NRC should be promptly notified.
No specific action or written response is required by this notice. If you
have any questions regarding this information notice, please contact the
appropriate NRC regional office or this office.
