Mich. Admin. Code R. 333.5404 - Conditions of operation
Rule 404.
(1)
Operation shall meet the requirements of R 333.5317 excluding subrules (2),
(5), (6), and (11).
(2) The output
of the x-ray generator should be calibrated initially before use for the
treatment of animals. It should also be recalibrated after each tube
replacement and after all changes or replacement in the generating apparatus
which could affect a change in the x-ray output. Check calibrations should be
made on an annual basis and records of all calibration maintained for not less
than 5 years.
(3) Patients shall
not be hand-held in position for radiation therapy. Mechanical supporting or
restraining devices shall be used if restraint is required.
(4) An individual shall not be permitted in
the treatment room when the tube is operated at any potential.
(5) The x-ray tube of a contact therapy
machine as defined in R 333.5321(3) shall not be hand-held during irradiation.
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 the apparatus is
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 are necessary to prevent accidental exposure to
the useful beam.
(6) Lead, lead
rubber, lead foil, and similar materials used for limiting the field, should
not transmit more than 5% of the useful beam under the conditions at which the
machine is operated for therapy.
