The demon-stration room may be made to intervenebetween the dark room and the examinationroom. The best protection is otTered the operatorwhen he is entirely out of the room containingthe x-ray tube. This is accomplished byplacing a small room between the demonstra-tion room and the examination room. Wemay call this the machine-operating room,inasmuch as from here the apparatus is manip-ulated, the tube regulated and the lights con- In larger laboratories it frequently becomesnecessary to remove the fluoroscopic apparatusto another room in order that these examina-tions may be made without interfering withthe routine radiographic work. Under thesecircumstances, the fluoroscopic room shouldadjoin the machine-operating room and theexamination room. In some laboratories thevast majority of the examinations are fluoro-scopic, the plate being but supplementary, forpurposes of record, and this form of exam-in
