R 333.5323 Conditions of operation.

Rule 323. (1) Operation shall comply with the requirements of R 333.5317. (2) If the x-ray tube of a contact therapy machine as defined in R 333.5321(3) is hand held during irradiation, the operator shall wear protective gloves and a protective apron. When practical, a cap of at least 0.5 millimeter lead equivalence should cover the aperture window of the tube housing of the apparatus when not being used. Because the exposure rate at the surface of the window of contact therapy and beryllium window machines may be more than 10,000 roentgens per minute, extreme precautions shall be taken to prevent accidental exposure to the useful beam.
