Products | Kolga LLC: Custom High-Density Shielding Solutions
At Kolga LLC, as a premier manufacturer of specialized containment and detection hardware, we serve the most demanding sectors including nuclear research, medical imaging, and industrial non-destructive testing. Our commitment to precision engineering ensures that every product, from our bulk lead shields to our patented beakers, meets the highest standards of safety and performance.
Radiation Detection Shields
High-performance radiation detection shields are the cornerstone of any sensitive spectroscopy laboratory. These units are designed to isolate detectors from ambient radiation, allowing for the precise measurement of samples with minimal background interference. Kolga LLC provides a range of shields tailored for High Purity Germainium (HPGe) and Sodium Iodide (NaI) detectors.
- Kolga Model A380 High Performance Shield
The Model A380 represents the pinnacle of bulk shielding for high-purity germanium (HPGe) detectors. This top-opening shield features 152 mm (6 inches) of certified DOE Run virgin lead. To ensure the highest data integrity, the A380 includes a graded lining consisting of 1 mm of tin and 1.5 mm of oxygen-free copper. The unit is finished in light gray epoxy and features a low carbon steel outer jacket for long-term durability in laboratory environments.
- Kolga Model A350 and A340 Series
Designed for versatility and performance, the A350 and A340 models provide 102 mm (4 inches) of virgin low background lead shielding. These models are ideal for facilities requiring robust protection in a more compact footprint than the A380. Like their larger counterparts, they utilize graded linings of tin and copper to enhance detection sensitivity. These shields are frequently utilized in radiation shielding for nuclear applications where consistent, repeatable results are mandatory for safety and compliance.
- Kolga Model A320-1 and A320-2 NaI Shields
For users utilizing Sodium Iodide (NaI) detectors, the A320 series offers specialized 50 mm (2 inch) thick lead shielding. The A320-1 is optimized for one-liter samples, while the A320-2 is designed for two-liter configurations. Both units feature the same high-quality graded liners found in our larger shields, ensuring reliable measurements. These units include rigid mounting plates for secure installation on tables or floors.
X-Ray Shielding
Industrial x-ray shielding plays a critical role in maintaining safety and operational integrity across a vast array of sectors. From aerospace non-destructive testing to heavy manufacturing and energy production, the ability to contain high-energy radiation is a fundamental requirement. Without high-quality x-ray shielding materials in place, personnel are at risk of exposure, and sensitive nearby electronic equipment can suffer from signal interference or hardware degradation. Ensuring that a facility uses superior shielding is not just a matter of regulatory compliance; it is a commitment to the longevity of the infrastructure and the well-being of the workforce.
As industries evolve and x-ray technologies become more powerful, the demand for precision-engineered barriers increases. Kolga LLC is recognized as a top provider of industrial x-ray shielding solutions and materials, including specialized configurations for radiation shielding applications. By providing materials with consistent density and verified attenuation properties, we help our clients create controlled environments where high-energy imaging can be performed safely and accurately. Our expertise ensures that even the most complex shielding challenges are met with reliable, high-performance solutions.
Lead & Tin Components
Kolga LLC provides a wide variety of lead and tin components designed to meet the specific technical requirements of radiation measurement and beam management. Our components are essential for systems that require directed radiation paths or precise monitoring of exposure levels. We work with high-purity materials to ensure that every component performs reliably under the rigorous conditions of industrial and research environments.
- Collimators and Beam Management
Precision-machined collimators are vital for shaping and directing radiation beams in both imaging and therapeutic applications. By using high-density x-ray shielding materials, these components prevent beam divergence and protect surrounding areas from unnecessary exposure. Our fabrication process ensures that collimators meet exact geometric tolerances, which is a critical factor in the success of any industrial x-ray shielding system.
- Dosimeters and Measurement Hardware
Accurate radiation monitoring relies on the integrity of the housing and internal components of dosimeters. We provide the specialized lead and tin parts necessary to shield internal sensors from unwanted interference, ensuring that readings remain accurate over time. This precision is particularly important for radiation shielding for nuclear applications, where tracking cumulative exposure is a primary safety mandate.
Low Background Lead
For facilities performing ultra-sensitive measurements, the isotopic purity of the shielding lead is paramount. Kolga LLC offers an extensive range of low background lead options to meet the varying sensitivity requirements of our clients. Our standard low background lead is available in certified activity levels of less than 35 Bq/kg, 30 Bq/kg, and 25 Bq/kg. For the most demanding research environments, we provide ultra low background lead with activity levels as low as 5 Bq/kg. These high-purity radiation shielding materials are essential for minimizing the intrinsic radiation that could otherwise obscure delicate data.
Marinelli Beakers
The geometry of a sample is just as important as the shielding surrounding it. Kolga LLC’s patented Marinelli beakers are designed to maximize counting efficiency by “wrapping” the sample around the detector head. This allows for a much larger sample volume to be analyzed in a shorter amount of time compared to standard cylindrical containers.
- Patented KB Model Marinelli Beakers
Our KB Model beakers are a great choice for gamma spectroscopy. They are available in various sizes to accommodate detectors with end cap diameters up to 3.5 inches.
- Specialized Lid Options
To prevent spillage and cross-contamination, Kolga beakers feature unique lid designs. We offer both a traditional snap-on style and a patented screw-on style. The screw-top versions include a built-in sealing ring, ensuring leak-proof operation even for sensitive or hazardous liquid samples. Both versions have been pressure-tested to ensure air-tightness, making them suitable for radiation shielding for nuclear applications where gas-phase isotopes must be contained.
- Integrated Handling Features
Each Kolga Marinelli beaker is equipped with a built-in gripping handle. This feature is not merely for convenience; it allows for the safe and easy removal of the beaker from deep sample counting shields. This reduces the risk of accidental drops or spills, which is a vital safety consideration when working with radiation measurement systems.
