25 Pa. Code § 228.33a - Facility and shielding requirements
In addition to the requirements in Chapter 219 (relating to standards for protection against radiation), the following are required:
(1) The control panel shall
be located outside the treatment or irradiation room.
(2) For accelerators not used in the healing
arts, provision shall be made to permit continuous observation of the material
being irradiated and any transfer or conveyance of material within the
irradiation room.
(3) For
accelerators used in the healing arts, provision shall be made to permit
continuous observation of and communication with the patient during
irradiation.
(4) Windows, mirror
systems or closed-circuit television viewing screens used for observing the
patient or the material being irradiated shall be located so that the operator
can maintain direct surveillance over both the control panel and the patient or
the material being irradiated.
(5)
If the surveillance conducted under paragraph (4) is provided solely by
electronic means, and if a malfunction of this surveillance equipment occurs,
irradiation activities shall cease until repair of that surveillance equipment
is performed and the equipment is found to be functioning normally.
(6) Irradiation or treatment room entrances
shall be provided with warning lights in a readily observable position near the
outside of access doors. These will indicate when the useful beam is
on.
(7) Interlocks shall be
provided so that entrance or access doors are closed before irradiation or
treatment can be initiated or continued.
(8) For accelerators used to irradiate
materials by means of a transfer or conveyance system, a means shall be
provided which either terminates the irradiation or prevents entry if an
individual attempts access to the irradiation room.
