Equipment and Materials:

A properly calibrated survey meter, cotton tipped applicators, liquid
detergent, alcohol and/or alcohol prep pads, zip-locked plastic bag or
facsimiles, gloves and elongated tongs or forceps.

Sample Collection Procedures:

NOTE: When working
with potentially radioactive contaminated materials or with large activity
sources such as teletherapy, brachytherapy, or eye applicator sources, the use of
safe radiation handling safety procedures should be reviewed and followed. It is
very important to use Time, Distance, and Shielding to reduce possible radiation
exposures to As Low As Reasonably Achievable (ALARA) levels. The wipe/leak test
of large activity sources shall always be done with the elongated forceps to
utilize the radiation safety concept of distance. Never under any circumstances
should brachytherapy, teletherapy, or eye applicator sources be wiped with the
fingers holding the alcohol prep.

1. The wipe/leak test sample shall be taken from the nearest accessible
   surface to the source or device, or the container surface for a radioactive
   shipment. A 100 cm squared area (10 cm x 10 cm) shall be wiped on packages.
2. Place gloves on hands and moisten the wipe test specimen with either
   detergent or alcohol.
3. Wipe the surface area to be wipe/leak tested.
4. Place the wipe/leak test specimen into the zip-locked plastic bag and seal
   zip-lock.
5. Label the plastic bag for identification of the device and/or
   area, including the date.
6. Evaluate gross contamination with the survey
   meter. (If the leak/wipe test specimen shows an activity twice that of natural
   background, consider gross contamination is present and immediately notify this
   consultant licensee for corrective action in accordance with TRCR 11.7D)
7. In the case that no gross contamination is present, the leak/wipe test
   specimen may be mailed or otherwise transported to this consultant licensee for
   analysis.
8. A leak/wipe test report will be sent to the customer after
   evaluation is completed.
