For hospital E-kits supplied by the South Texas Project, friskers are response checked on the lowest scale only using a jig that incorporates thoriated welding rod as the source. We look for response within a predetermined acceptance window. Using the thoriated welding rod material as the source eliminates the need to re-establish the response window due to decay. This approach was acceptable to the state.

Palo Verde would like to know: How does your site response check friskers, stored in E-Kits offsite, to prior to use. I.e.. Hospital E-kits Do you check all ranges to a known value with acceptable pass / fail criteria or just look for general response / needle deflection?
