The papers of Ronald K. Smeltzer document his work on radiation hardening for charge coupled devices and metal oxide semiconductors. Telephone logs which provide a record of meetings and conversations with scientists at RCA and other laboratories document planning meetings and technical data, as well as Smeltzer's conversations regarding projects from other organizations and companies, such as General Electric, NASA, and the Pentagon.

Three of Smeltzer's lab notebooks (1978-1989) can be found in Record group 26.
