title: [Sources of x-rays in school].
abstract: Exposure of teachers of physics to x-radiation emitted by instruments which are used for demonstrating rarefied gas discharges during physics lessons at secondary schools is discussed. The measurements performed provide an explicit evidence that an effective, anual exposure dose under the most unfavourable conditions does not exceed admissible levels according to Polish regulations pertaining to persons non-occupationally exposed to ionizing radiation.
