investigation resulted when the employee terminated his employment before a "Q" clearance was required, The "QR" clearance was a reinstatement of a "Q" clearance which nad been previously active but had been terminated because of nonemployment on AEC work requiring clearance. The "QE" clearance was a "Q" clearance granted under emergency conditions by the Manager of the Atomic Energy Commission, Santa Fe Operations Office, or the Commanding General of Joint Task Force 3. It was granted only in cases of real emergeacy when it was essential that the individual be employed or given access to Restricted Data prior to the completion of a full investigation by the FBI. This clearance was used very sparingly and was requested only in cases of extreme need. Throughout the entire operation, only 13 were requested, All of these were granted, and none resulted in later repercussions of any kind, PROCESSING PROCEDURES After a prospective employee had been interviewed in the Personnel Department and was considered acceptable for employment, he was given the forms to be completed for security clearance processing. These consisted of a personal history questionnaire, a security acknowledgment, a fingerprint card, and an extract of the Atomic Energy Act of 1946. In the case of overseas employees, there was added a Navy identification card and a Navy identification file sheet. The personnel security questionnaire was the only one filled out in detail by the applicant. It was rather troublesome because it required a large amount of detailed information on the background of the applicant, including past employment, former home addresses, citizenship status, organization memberships, etc. Furthermore, it was almost invariably filled out incorrectly, and it was usually necessary that a security interviewer go over individual entries with the applicant in order that acceptable detail would be included, The interviewer verified the citizenship of the applicant by viewing birth certificate, naturalization papers, or whatever acceptable evidence of citizenship was available and marked on the application that he had examined the military discharge for military service claimed by the applicant, The applicant was then photographed and fingerprinted, and, for overseas employees, the information required for the Navy identification card was obtained, An initial security lecture was given at the time of completion of the questionnaire, Later, usually at the time of actual hiring, a second security lecture was given. This lecture varied with the job status of the applicant and was different for Home Office and Jobsite employees, At the time of the second lecture, Jobsite employees were shown a motion picture based on security activities and requirements of the Sandstone Operation,
