SSINS No.: 6835IN 85-07UNITED STATESNUCLEAR REGULATORY COMMISSIONOFFICE OF INSPECTION AND ENFORCEMENTWASHINGTON, D.C. 20555January 29, 1985IE INFORMATION NOTICE NO. 85-07: CONTAMINATED RADIOGRAPHY SOURCE SHIPMENTS

Addressees

All NRC licensees authorized to possess industrial radiography sources.

Purpose

This information notice is intended to alert receivers of radiography sourcesof recent discoveries of removable contamination on shipping containers arriv-ing at licensee sites from a source supplier. It is expected that recipientswill review the information in this notice for applicability to their facili-ties and consider actions, if appropriate, to preclude a similar problem. How-ever, suggestions contained in this information notice do not constitute NRCrequirements; therefore, no specific action or written response is required.

Description of Circumstances

A large east coast shipyard recently received three consecutive iridium-192radiography source shipments from Gamma Industries, an Agreement State sup-plier, that exhibited significant contamination on the bottom of the sourcechangers contained within an overpack. Radiation levels on removable contami-nation wipes ranged up to 0.4 milliroentgens/hour. Several shipyard employeeswere contaminated, and their vehicles and homes were required to be surveyedto ensure that no contamination was spread.Discussion:Gamma Industries will be sending leak test kits to users of their Model C-10source changers and will be requesting that the exterior of the changers bewiped and the wipes returned to Gamma Industries for analysis. However,because source changer models other than the C-10 are loaded in the same wayby Gamma Industries, it is suggested that licensees survey other types of GammaIndustries shipping containers in their possession by wiping the entire externalsurface with a paper towel and then surveying the towel in an area of low back-ground radiation with their most sensitive survey meter set to the lowest scalerange. If contamination is detected, it would be advisable to contact thecontainer shipper and the appropriate NRC regional office.Although contamination surveys are not specifically required by 10 CFR 20.205because the sources are a special form, the NRC suggests that surveys for gross8501250352
