Do X rays FLOAT or LINGER in the Air??

Patients, and even some healthcare workers, occasionally fret about getting close to an x-ray department or room, for fear that the lingering radiation will inflict harm upon them. This video works to dispel some ideas that x-ray rooms are dangerous, even when x-rays are not being administered.

Hi sir, i have an x ray machine with 200kHz frequency, 65kVp and 7mA. If i use kodak E speed films, how much exposure time is safe as a whole in a single day. I am planning to buy an rvg only because of its low exposure requirement. RVG is not affordable for me at present situation. Should i buy a lead apron and use iopa or should i have to buy rvg. Awaiting your reply.
