In order for Surplus Stores to accept items which have contained or may have been contaminated with radioactive materials each item must be:

See SPPM 9.60. For more information, contact the RSO; telephone 335-8916.


Prior to sending any property to Surplus Stores which is indicated on the Item Evaluation form as containing radioactive materials, the authorized user is responsible for completing the steps listed below. See SPPM 9.40 for information concerning authorized user status.

For questions regarding appropriate monitoring methods, decontamination procedures, or how to handle a situation where contamination cannot be removed, contact the RSO.

Radioactive Material Decontamination

The authorized user must decontaminate and survey each item of University equipment which has contained or may have been contaminated with radioactive materials prior to disposition. See SPPM 9.80 and the Radiation Protection Program Manual (RPPM) for a complete discussion of radioactive decontamination procedures. (NOTE: Only RSO personnel may remove radioactive materials labels or stickers.)


The following are examples of radioactive material decontamination procedures. NOTE: Authorized users are to coordinate more extensive decontamination efforts with the RSO.

Method #1

Tape patch for dry or localized contamination.

Method #2

Wiping dust or accumulated contamination.

Monitoring and Confirming Survey

The authorized user must decontaminate and monitor for radioactivity each item which is to be sent to Surplus Stores. See SPPM 9.60.

The authorized user must contact the RSO to perform a confirming survey to ensure the item is decontaminated.

Property Release Survey

The RSO affixes a completed, reviewed, and stamped Laboratory Survey form to each item which RSO personnel have surveyed and found to be free of radioactive contamination. See SPPM 9.60.

Removing Labels

Following a successful decontamination and confirming survey RSO personnel must ensure that all radioactive materials labels or stickers are completely defaced or removed. (NOTE: Only RSO personnel may remove radioactive materials labels or stickers.) See SPPM 9.60 and the RPPM.

Item Evaluation Form

The authorized user must attach a completed Item Evaluation form listing the specific radioactive material(s) which caused the contamination and the decontamination method which was used.

Complete and/or print the PDF master on 20.77.4 to obtain copies of the evaluation form. Attach a copy of the property release survey to the evaluation form. See above.
