South Australian Consolidated Regulations South Australian Consolidated Regulations69—X-ray tubes incorporated in X-ray analysis apparatus
(1) An X-ray tube
incorporated in an X-ray analysis apparatus must be enclosed in a tube housing
every aperture of which is covered—
(a) by a
shutter; or
(b) by a
completely shielded enclosure, all entrances to which (apart from the
aperture) are interlocked so that the opening of any such entrance immediately
de-energises the X-ray tube.
(2) The tube housing
and the enclosure referred to in subregulation (1) must be
adequately shielded.
(3) The X-ray tube and
the tube housing of an X-ray analysis apparatus must be interlocked so that
the removal of one from the other de-energises the X-ray tube.
(4) If a cover
providing direct access to the inside of the X-ray tube housing is removed
from an X-ray analysis apparatus, the X-ray tube must be de-energised.
