IE INFORMATION NOTICE NO. 86-67:

PORTABLE MOISTURE/DENSITY GAUGES: RECENT

INCIDENTS AND COMMON VIOLATIONS OF REQUIREMENTS

FOR USE, TRANSPORTATION, AND STORAGE

Addressees

All NRC licensees authorized to possess, use, transport, and store sealed sources

contained in portable gauges used to measure the moisture content and/or density

of construction materials.

Purpose

This notice is intended to bring to the attention of licensees the recent

increase in incidents involving the use, transportation, and storage of portable

gauges and the number of common violations identified during NRC inspections.

It is expected that recipients will review the information for applicability

to their facilities and consider actions, if appropriate, to preclude similar

problems from occurring at the4r-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

An abnormally high number of incidents have occurred recently where portable

moisture/density gauges have been damaged at temporary job sites by heavy

construction equipment or where the gauges have been lost or stolen from

licensee vehicles during transportation. Gauges damaged at construction sites

were left unattended.

Gauges lost or stolen from vehicles were not secured to

the vehicle or were stolen while left unattended by the users.

Inspections initiated by these incidents and routine inspections that have been

preformed reveal common violations of NRC requirements.

These violations

include failure to:

(1) have a shipping paper in the transport vehicle

(2) transport gauges in authorized packages

8608120509

_IN

86-67 August 14, 198,6- (3) maintain records of tests performed on transport cases and on sealed

sources

(4) use authorized and/or qualified users

(5) use authorized storage locations

(6) conduct leak tests and physical inventories to conduct those tests and

inventories within the required time interval

(7)

wear film or TLD badges or estimate doses to personnel who had lost their

badges or evaluate and report possible overexposures

Discussion:

The cause of these incidents, invariably, is the failure of the gauge users to

secure and maintain control over the gauges.

10 CFR 20.207 requires that licensed material (in these cases the sealed

sources in the gauges) must be under the constant surveillance and immediate

control of the licensee or must be secured in storage when in an unrestricted

area.

An unrestricted area is defined in 10 CFR 20.3(a)(17) as any area to

which access is not controlled by the licensee for purposes of protection of

individuals from exposure to radiation and radioactive materials and any area

used for residential quarters.. Agonstruction site is usually an unrestricted -

area; so the licensee must constantly control access to the gauge while in.

storage or during use at the site.-.

NRC licensees transporting portable gauges are subject to 10 CFR 71. 10 CFR

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 licensee or private vehicles

are acting as private shippers and, as such, must comply with the DOT regulations

governing shippers.

49 CFR 177.842(d) requires that packages containing

radioactive material (i.e, the gauge in its case and containing radioactive

sealed sources) must be blocked and braced to prevent movement of the package

during transportation.

For pickup trucks, this requirement is usually met when

the gauge, in its case, is chained or tied to the bed of the truck.

Licensees are reminded that they must use, transport, and store the gauges in

accordance with the conditions of their NRC license, other commitments made to

the NRC, and applicable regulations. A discussion of other requirements and

license conditions commonly violated is attached.

IN 86-67 August 15, 1986 No specific action or written response is required by this notice. If you

have any questions regarding this information notice, please contact the

Regional Administrator of the appropriate NRC regional office or this office.

Attachment 1 OTHER COMMON VIOLATIONS

49 CFR 172.201, 172.202, 172.203(d), 172.204, and 177.817(e) specify the contents

of the shipping paper and the location in a vehicle where the shipping paper

must be stored.

Shipping papers must not be stored in or on the case containing

the gauge or in the glove compartment of the vehicle. .

49 CFR 173.475 requires that before each shipment the shipper ensures by

examination or appropriate test that the proper shipping case or box is used, that the case is in unimpaired physical condition, and that each closure device

on the case is properly installed, secured, and free of defects.

49 CFR 172.301, 172.304, 172,308, 172.310, 172.403, and 178.350 specify the

labeling and marking of the case used for shipping.

Vehicles transporting one

or more gauges usually do not require placards (49 CFR 172.504, Table 1).

49 CFR 173.415(a) and 173.476(a) require that shippers maintain on file results

of tests conducted on shipping cases and on the sealed sources contained in the

gauges.

Licensees can usually obtain these test results from the manufacturer

of the gauges.

Gauges must be used only by-properly authorized and trained individuals. A

common license condition usually names individuals who are authorized to use the

gauges or who must be~physically present to supervise their use.

Occasionally, licensees are allowed by a license condition to name authorized users.

Authorized

users must have successfully completed an approved training course given by the

manufacturer or a consulting firm. Certain licensees are authorized to provide

in-house training.

The Radiation Protection Officer (RPO) also may be named

on the license, but is always specified in documents submitted to the NRC.

When

this individual is no longer employed as RPO, the licensee must request an

amendment to the license to rame a replacement.

A specific license condition or statement in a submitted document specifies the

temporary and permanent storage facilities for the gauges.

Private residences

(including basements and garages) are usually not allowed as storage facilities.

Vehicles used to temporarily store gauges overnight at private residences must

not be.used by individuals who are not authorized users for purposes other than

those authorized on the license.

For example, friends or relatives of an

authorized user must not use a vehicle containing a gauge unless those individuals

are performing a purpose authorized on the license as authorized users.

A specific license condition will specify the interval between leak tests.

This

interval is usually 6 months and may be greater on some licenses for gauges that

are stored and not being used.

Many licensees also are required by license

condition to conduct-a physical inventory at 6-month intervals.

IN 86-67 August 15., 198(

Attachment 1

Page 2 of2

2 Licensees are usually committed by a referenced document to wear film or TLO

badges when using or transporting the gauges.

When not worn by the users, the

badges must not be stored near or on the gauges.

For lost badges, the licensee

is required by 10 CFR 20.201 to estimate the user's dose for the period for

which the badge was lost.

For film or TD badge reports indicating that doses

greater than the limit in 10 CFR 20.101 may have been received, the licensee

must evaluate the reading (10 CFR 20.201) to determine if it has been caused by

an actual exposure to the user.

This evaluation includes, at a minimum, questioning the user about the use of the gauge and badge and having the film

or TLD badge processor reexamine the badge.

Although, true overexposures of

gauge users are rare, the occurrences must be reported to the NRC as required

by 10 CFR 20.405.
