>
>Recently a shipment of 133 of our patented double wall BestŪ Iodine-125
>sources (approximately 0.3 mCi per source) was sent by us to one of our
>customers. Upon receipt of the shipment, the customer examined the sources
>and found them to be in good condition, having received the correct number
>of sources and activity. Nine days after the date of shipment, the customer
>began to load them in needles after sterilizing them. Following the loading
>of all of the sources in the needles and during radiation survey of the
>area, the customer found microcurie level of contamination in the
>sterilization tray. The customer did not find any contamination in the glass
>vial or the stainless steel container in which the I-125 sources were
>shipped and stored. Also, no contamination was found in the isotope
>calibrator or sterilizer. No one at the customer's site received any
>thyroid uptake or radiation exposure. We were informed of the problem
>immediately, and all of the sources were returned to us for evaluation and
>investigation.
>
>Upon return of the shipment to us, all 133 I-125 sources were inspected and
>leak tested. We found one of the sources to be damaged and leaking. The
>other 132 sources were in good condition and leak free. The damaged source
>was examined under a video microscope.
>
>These sources were manufactured at least two (2) weeks prior to shipping and
>subjected to autoclave, dry and wet leak testing. In addition to multiple
>leak tests performed, all of our sources are subject to dimensional and
>visual inspections before shipping. Our patented double wall BestŪ
>Iodine-125 sources have thick double wall construction.
>
>In summary, when the above-mentioned shipment was made, all 133 sources were
>in good condition and had passed our autoclave, dry and wet leak tests, in
>addition to dimensional and visual inspections. No contamination was
>detected while in storage or during and after calibration at our customer's
>facility. All of this clearly points to the fact that the customer received
>the sources from us in good condition without damage or defect.
>
>On April 24, 2001, the U.S. Nuclear Regulatory Commission (USNRC) conducted
>a special inspection at Best and reviewed our production and QA procedures
>related to the manufacturing of patented double wall BestŪ Iodine-125
>sources. The inspectors concluded that our procedures are in full
>compliance with all regulations and meet the requirements of the USNRC. No
>violations were found.
