This Anon provided instructions for filling out Q forms if applying for SS/FBI. Notice this paperwork refers to Q Clearance.
I did a little research on a name on this one page I included here - Edward B. Giller, Acting Assistant Director for Research and Development.
He was an Assistant General Manager for Military Application, Atomic Energy Commission, Germantown, Maryland
