DOOR SYSTEM SUPPLIER: RPP, USA
RPP’s swing radiation shielding doors (neutron
doors) are constructed with ¼" thick A-36 steel face plates.
A-36 steel flat bars are used for the stiles and the
reinforcement inside the door . Flat bar thicknesses for the
stiles and reinforcement are dictated by the core of the door.
The core of the door will consist of the shielding requirements
(typically lead and borated polyethylene) as determined by a
licensed physicist. We can also design the door with extra space
inside for future upgrades which may require more shielding. The
door finish is completed in the factory with a paint grade
primer. RPP offers safety features for radiation shielding doors
(neutron doors) such as motion sensors, pressure sensitive tape,
and battery backup.
Our RPP designed frames for neutron swing door
systems are constructed with ¼" thick A-36 steel. Five gussets
at ¼" thick and five pieces of bent flat bar steel at ½" thick
are welded to the jambs (see detail-link). This reinforcement
ensures longevity for the radiation shielding door (neutron
door) and prevents misalignment between each of the hinges. The
gussets have a dowel system to allow the concrete to set
securely to the frame when poured. This RPP designed framing
system is the most durable available.
RPP’s automatic openers for radiation shielding
doors (neutron doors) are the most reliable and well-built in
the industry. Our vendor’s vast experience of what works and
what does not is based upon years of field experience. The 1502
series electric operators are specifically designed to eliminate
the problems that other manufacturers have had with their
designs. The units are built with the very best industrial
components on the market today. Specific issues like output
shaft failure, limit switch sensitivity, torque output, torque
output control, operator mechanical drive protection, and door
inertia control are all diminished or eliminated by design. The
electric operators require a 120 VAC power source that we
convert to 90 VDC. The advantage of DC is that we can better
control the operation of the door operator. RPP will make final
adjustments to the door but all conduit work and electrical work
will be completed by others. See more details on swing door

LINEAR ACCELERATOR VAULT SYSTEMS
supplier in USA, NELCO offers a variety of solutions for LINAC
vaults in new construction, renovations, upgrades, or additions. We
offer a variety of products to choose from, and if required, our
value engineering services can help you find the best solution for
your needs. Many of our solutions are modular, making them the
perfect solution for leased spaces, and allowing the freedom to
relocate if needed.
LINAC vaults include those for standard Linear Accelerators, IORT,
IMRT, Cyberknife, Gamma Knife, or CT Image-Guided IMRT Rooms.
Typically LINAC vaults are designed in one of two configurations,
mazed or mazeless.
Mazed Vault Systems
Mazed vaults are the frequently used and allow for a less heavily
shielded door system. In facilities where space is not an issue
mazed vaults can be a cost effective solution. NELCO’s swing door
systems used with mazed vaults can come with a partial open feature,
allowing for faster patient throughput.
Mazeless Vault Systems
Mazeless vaults allow for a smaller overall footprint in the
facility. It is recommended to use a slide door system in these
applications, because the door thickness needs to be increased.
However, mazeless vaults typically save approximately four hundred
square feet - with the premium construction costs for vaults, this
can provide a cost savings of approximately one-hundred thousand
dollars per vault.
Mazeless vaults also increase productivity, frequently allowing
centers to treat more patients throughout the day, increasing

MEGASHIELD MODULAR BLOCK
MegaShield™ was created by
as a competitively priced, modular alternative to a poured
cast-in-place (CIP) vault. Each MegaShield™ system is made up of
interlocking concrete blocks, available in both standard and high
density weights. These blocks are cast at a local, off-site,
pre-approved and qualified facility, allowing
to manufacture them during the permitting process. Blocks arrive on
site cured and ready to assemble, reducing construction time
significantly. MegaShield™ vaults can be assembled in as little as
The system can be erected outside a building, or
inside of most existing facilities, and can be used for a variety of
modalities. MegaShield™ can also be removed and relocated, making it
the ideal solution for leased spaces. When space constraints are an
issue, a hybrid model of MegaShield™ and other shielding, such as
Interlocking Lead Brick or High Density Concrete Blocks, can be
designed. Other options include site work, foundation work, interior
finish, and mechanical and electrical systems.

CUTOUTS & PENETRATIONS
When installing lead lined drywall (lead lined sheetrock, lead
lined gypsum), all cut outs, seams and penetrations will require
sheet lead or lead plate to ensure continuous shielding
throughout the room. Proper installation of additional lead
wherever penetrations are created will eliminate potential leaks
and ensure total protection.
Additional sheet lead can be supplied to easily allow for the
proper shielding of penetrations such as receptacles, light
switches, ducts and telephone/data cables.
