NRC INFORMATION NOTICE NO. 90-24: TRANSPORTATION OF MODEL SPEC 2-T

RADIOGRAPHIC EXPOSURE DEVICE

Addressees

All NRC licensees authorized to use, transport, or operate radiographic

exposure devices and source changers.

Purpose

This information notice is provided to alert licensees of a recent

change

the NRC Certificate of Compliance No. 9056, which imposes more restrictive in

requirements for proper transportation of the model SPEC 2-T radiographic

exposure device.

It is suggested that licensees review this information for applicability

operations involving transportation of radiography devices, and distributeto

it to persons responsible for proper transport of devices. However, notice does not constitute new NRC requirements, and no written response this

required. is

Description of Circumstances

A certificate of compliance is issued by the NRC when a specific package

the requirements of 10 CFR Part 71 and is approved by the NRC for meets

radioactive material. Conditions for proper transportation of transport of

the model SPEC

2-T radiographic exposure device are stated in NRC certificate of compliance

(COC) No. 9056 (Attachment 1). These conditions augment the requirements

the U.S. Department of Transportation and 10 CFR Part 71 of the Commission's of

Regulations for the transportation of radioactive materials.

Prior to this recent change, the COC specified that for transportation

than 110 curies of iridium-192, the radiographic exposure device of more

be within a protective overpack or transported by exclusive use must either

accordance with the requirements of 49 CFR 173.441(b). The shipment in

IN 90-24 April 10, 1990 The NRC was informed that the surface dose rate on the radiography device

could exceed 200 millirem per hour when loaded with 110 curies of iridium-192. maximum

Apparently, the radiation measurements used to determine the 110 curie device

between the surface of the

activity were not corrected for the distance cor- and the effective center of the radiation measurement instrument. This

rection was because of the small dimensions of the model SPEC 2-T depleted

uranium shield.

Discussion:

measure- The staff evaluated the information obtained from previous radiation maximum

ments and determined that the dose rates had been underestimated. The

to a surface dose rate

activity in the model SPEC 2-T device that corresponds conditions

of 200 millirem per hour is 45 curies of iridium-192. As a result, instead of

8 and 9 of the NRC's COC No. 9056 were amended to specify 45 curies was reduced

110 curies. Also, the maximum quantity of iridium-192 per package

from 240 curies to 225 curies.
