Vendor's Meeting

In keeping with the Health Physics Society's mission, "to encourage scientific,professional and public education" as it pertains to excellence in the science and practice of radiation safety, the ETCHPS has sponsored and supported public outreach and training sessions in East Tennessee areas near nuclear facilities (i.e. Oak Ridge and Chattanooga). Henry Lynn has organized these efforts and needs volunteers to help develop materials, make presentations. Please let Henry know by sending a note to his home email address at if you are interested  in assisting with this effort.
