X-ray and Darkroom
Planning
|
|
Site planning requirements may vary by state, so please contact your Lake Superior X-Ray representative for specifics. You may contact a LSX representative at 800-777-4518.
The following site plan guide is mainly for medical or chiropractic clinics. For Veterinary clinics please contact a LSX representative.
Location
The x-ray room can be located anywhere within your clinic. Ideally, the x-ray room
would be located on an outside corner that has two outside walls. This will reduce the
costs of lead lining. It is preferable that you have one door and no windows. If there
are windows, location and dimensions will be critical for placement of tube and/or bucky
stands. Windows will need shades to reduce light to enable you to see the collimator
light field for patient positioning.
Size
To minimize the size of the room required and maximize efficiency in your x-ray
department, it is recommended that a compact system be utilized. A minimum space of
eleven-feet-long by eight-feet-wide is suggested for the x-ray unit, but size
specifications of your unit will dictate the ultimate size of the room required. We can
place certain systems in a much smaller room. Contact your LSX representative, who
will provide a custom layout for your specific situation.
Power Supply Standard Frequency
When choosing your site , check for adequate power before purchasing property or
signing a lease. You may be able to negotiate the cost of bringing proper power to the
building if it is not already in place.
All wiring and grounding should be in accordance with National Electric Code or local code.
Electrical Requirements for Standard Frequency
Switched or fused disconnect box. 220VAC 100 Amp Service.
Power voltage range 203-248 VAC Single Phase.
L1 - L2 - Ground
Mount bottom of disconnect box 60" from floor
Recommended wire size: (from disconnect box to distribution panel)
50' - #2 copper 100' - #00 Copper 200' - 250mcm Copper Ground - 8AWG
Distribution Transformer KVA - 37.5
EMERGENCY DISCONNECT BOX MUST BE WITHIN ARMS LENGTH OF X-RAY CONTROL
Inadequate power could prevent the x-ray unit from operating within its state specifications and from meeting federal and state requirements.
Power Supply High Frequency
When choosing your site, check for adequate power before purchasing property
or signing a lease. You may be able to negotiate the cost of bringing proper
power to the building if it is not already in place. Disconnect box is the same but the actual power requirements differ as per below.
Electrical Requirements for High Frequency
Electrical Requirements for High Frequency X-ray Suite
Switched or fused disconnect box.
240VAC 125 Amp Service.
Power voltage range 208-240 VAC Single Phase.
Any line voltage below 212VAC will require a step up transformer (cost to Doctor is $325.00)
Line Interconnect: L1 - L2 - Ground (2 hot, 1 ground)
Mount bottom of disconnect box 60" from floor
Recommended wire size: (from disconnect box to distribution panel)
50' - #0 Copper 00' - #000 Copper 150'-MCM 250 Copper
Distribution Transformer KVA - 37.5
EMERGENCY DISCONNECT BOX MUST BE WITHIN ARMS LENGTH OF X-RAY CONTROL
Inadequate power could prevent the x-ray unit from operating within its state specifications and from meeting federal and state requirements.
Radiation Shielding
Generally, there is no specific requirement for shielding in each wall, but rather a
requirement to limit primary and scatter radiation to acceptable levels. The
shielding required is determined by the potential exposure to humans and takes
into consideration occupancy factors, distance, workload, energy and direction of
the primary beam. The operator is required to stand behind a protective lead
shield while making an exposure. The actual specifications of this protective
shield will vary from state to state. Check with the governing body in your
state for the exact specs.
Shielding may include cement block walls or lead-lined walls. Contact LSX for details.
