| SAM 9 Shields |
Specially designed to reduce employee downtime and to maximize efficiency by reducing background radiation levels at the Small
Article Monitor. Unique design is easily portable. All stainless steel with an attractive finish. |
| Secure Environmental Containers (SEC’s) |
For temporary storage of Low Level Radioactive Waste. Optimized cylindrical and rectangular configurations. Shielding thickness
from 4 to over 24 inches. "SEC" capacities to over 1300 cubic feet. 2, 3 & 5 modular piece assemblies to match site crane capacity. |
| Modular Water Shields |
All stainless steel construction. Ease of mobility for use anywhere. Vent and fill/drain hole on top and optional drain port on
bottom. Visual water level indicator. |
| Window Water Shields |
Rugged stainless steel tank with acrylic window on top half. Shielding equivalent of 1.5" lead (more available if required).
Corner eyebolts for easy lifting when empty. Casters lower the shield to floor level when filled to eliminate "toe shine". |
| Ball and Socket Shields |
Constructed of steel reinforced concrete with cylindrical ends that permit the shield to be positioned at angles up to 45 degrees
relative to each other. Interlocking ends significantly reduce any streaming at interface points. Carbon steel "straps"
function as stabilizer plates. Also available as stainless steel water shields. |
| Doublewal™ |
Walls are constructed of hollow concrete blocks then backfilled with gravel or soil. These may be used to shield sources of
radiation in storage. Almost any height, width and shielding thickness is available. |
| Modular Shield Logs |
Our standard size measures one foot square by eight feet in length and weighs approximately 1,200 pounds. Stepped
interlocking design reduces streaming at the adjoining log seam. Can be stacked to construct a shield wall. Two threaded
inserts facilitate lifting. Available painted or unpainted. |
| Drum Shields |
When doorways, elevators, floor drains and other obstacles make moving LLW from place to place a challenge, consider
a 30 or 55 gallon Drum Shield. Reusable, transportable either by crane, built in casters or fork truck, the Drum Shield
offers an inexpensive way to transfer LLW. |
| Sample Storage Shields |
Constructed of 11 gauge stainless steel and lead, for durability and ease of decontamination. Used for storage during
characterization and testing of LLRW samples. Attractive, safe approach to shielding. Standard model offers stainless steel
lockable hinged door which provides access to the 8"x12"x24" internal area. Other sizes designed to suit your needs. |
| Frisker Caves |
To get an accurate reading of small tools and routinely used articles; to cut down background radiation, count time, and exposed
lead bricks, use the Dufrane Frisker Cave. Standard model inside dimensions: 8" wide 13.75" deep 8" high. Lead bricks
are used to surround internal cavity. |
| Process Shields |
Generally cylindrical steel reinforced concrete container. A fully removable lid with central port/plug for process
equipment. The shields are sized to accept standard HIC's. Special units are available as modular panels where access,
size or weight restrictions are specified. |
| Security Barriers |
Steel reinforced concrete units that are Dufrane’s solution to an efficient mobile barrier system. The modular
interlocking security shields are available in 8’ or 10’ heights with or without a gun port. The module sits
on a wide base of 3’ that can taper to either a 12” or 18” riser. |
| Transfer Bells |
Consisting of a bell and a lifting apparatus, a typical cross section of 11” concrete encased within 1/2”
steel inner outer shells provides 2 3/4” of lead equivalent (Co60) shielding. A similarly constructed Lid is provided
to permit the Transfer Bell to be used as a temporary storage shield. |
| Blanket Racks |
Fabricated from high carbon stell with continuous welds and a finish coat of enamel paint for ease of
decontamination. Each Blanket Rack has the capability of standing alone or the ability to interlock multiple
racks to form an extended or solid wall. |
| Pipe Shielding |
Available in various sizes in the range of 2-inch diameter through 48-inch diameter pipe detector shield
and a 24-inch diameter turbine deck pipe/valve shield. The majority of shields are lead encased in carbon or
stainless steel with the option of a solid steel shield as well. |
