February 15, 2018


The APS Safety Radioactive Sample Safety Review Committee (RSSRC) advises the PSC Deputy ALD Operations on the radioactive samples to be used at the APS and the adequacy of controls in place for the duration of their use.

The RSSRC reviews the radioactive material samples proposed to be run at the APS to ensure that they fall within established safety envelopes of the APS.


The RSSRC members are appointed by the PSC Deputy ALD Operations. The current members of the RSRC are:

W. VanWingeren PSC - Chair
L. Soderholm CSE
J. Vacca ESQ
B. Glagola PSC
M. Li NE
J. Almer XSD
E. Alp XSD
M. Rivers


Joanne Stubbs PUC
Paul Rosse HSE/PSC
  • The PSC User Safety Officer will notify the RSSRC of any samples that are proposed for use.
  • The Radiation Scientist and Health Physics will pre-review all proposed experiments to determine if a review by the full committee is needed.
  • The Chair will coordinate the review by committee members and provide feedback to the Beamline and APS.
  • Beamline staff from the affected beamline will participate in the review.
  • Outside experts are brought in on an as needed basis
  • The spokesperson for the experiment, the beamline, and the APS Experiment Safety Review Board (ESRB) will be notified of the final status of the review.
Frequency of Meetings

Meetings are held on an as-needed basis for review of samples and experiments. In addition, the RSSRC will meet at the end of each APS running period to discuss the reviews and feedback from experiments completed during that cycle, as needed.
