title: [Exposure rates in fluoroscopy in Quebec].
abstract: For the past two years, the authors have measured by means of an ionization chamber the exposure rates of 155 fluoroscopic systems. Of these, 42% measured beyond the maximum of 5 R/min recommended by radiation protection codes. Systems linked to a television chain functioned at generally lower levels. There was no significant difference between remote controlled and non remote systems. However, appreciable differences between the units of two manufacturers were observed. The corrective measures which must follow this survey will result for Quebec in a saving of 2.0 millions of rads to the population which becomes, without doubt, the single most important factor of radiation protection.
