Dear Radsafers I am looking for sources of training aids or video -films on QA/QC for Environmental Radiological Laboratories, and also "clean room" operations from a QA/QC. BTW, does anyone know a listserv for clean room operations? Thanks in advance. rcraft@tgn.net Roy C. Craft CHP 1707 Pecan St. Bay City, TX 77414 (409)245-9991
