Products
Kolga offers a range of industrial radiation shielding and related solutions to meet your needs. We offer a portfolio of shields for gamma spectroscopy. We also offer components for industrial X-Ray Imaging.
- Radiation Detection Shields
Radiation Detection Shields
Kolga specializes in the design and manufacture of high-performance industrial radiation detection shielding, specifically engineered to provide a radioactively low background environment for high purity germanium (HPGe) and sodium iodide (NaI) detectors. Our shields, such as the A350 and A320 series, are constructed from certified DOE Run virgin low background lead. Each unit features a precision-engineered graded liner—typically consisting of a tin layer and an oxygen-free copper layer—to suppress lead x-rays and ensure the highest possible sensitivity for gamma spectroscopy and nuclear research applications.
- X-Ray Shielding
X-Ray Shielding
We provide comprehensive x-ray shielding solutions tailored for demanding industrial imaging applications. Our components and assemblies are designed to mitigate radiation leakage and protect personnel and sensitive equipment in non-destructive testing (NDT) environments. Our x-ray shielding products combine high-density materials with robust structural integrity to meet stringent safety standards.
- Lead and Tin Components
Lead and Tin Components
Kolga produces a wide array of precision lead and tin components, including collimators, dosimeters, x-ray windows, sheet lead, and lead foil. These products are manufactured to exact specifications to serve as critical elements in larger radiation protection systems. By utilizing advanced manufacturing techniques, we ensure that every component provides uniform density and reliable attenuation properties, whether used in medical diagnostic equipment or industrial isotope handling.
- Low Background Lead
Low Background Lead
We offer premium low background lead ingots and custom shapes for applications where minimal intrinsic radiation is paramount. Our inventory includes lead certified at various activity levels, including <35 Bq/kg, <25 Bq/kg, and ultra-low background options reaching <5 Bq/kg. These low background lead ingot materials are essential for researchers and manufacturers building high-sensitivity radiation detectors that require the lowest possible interference from cosmic or environmental sources.
- Marinelli Beakers
Marinelli Beakers
Our Marinelli beakers are designed for the efficient geometry-based measurement of environmental samples. These specialized containers allow the sample to surround the detector, maximizing the counting efficiency for low-level gamma-ray emissions. Manufactured with high-quality, non-contaminating materials, our beakers are a staple in environmental laboratories and nuclear power plant monitoring facilities.
Capabilities
Lead Casting and Mold Design
Kolga offers specialized lead casting services, utilizing custom mold designs to create complex geometries and high-density shielding components. Our casting process is strictly controlled to prevent inclusions and ensure the structural homogeneity of the lead.
Multi Axis CNC Machining
Our facility features advanced multi-axis CNC machining centers, including 5-axis and 3+2 axis milling machines from Matsuura, Mori Seiki, and Haas. This equipment allows us to machine high-density shielding materials with extreme precision, achieving tight tolerances on complex parts. By integrating CNC turning and milling, we provide a complete machining solution for components ranging from small detector housings to large-scale industrial shielding plates.
Metal Fabrication
We maintain a full-service metal fabrication shop staffed by certified welders capable of TIG, MIG, and spot welding. Our fabrication capabilities include CNC turret punching and CNC press brake forming, allowing us to work with a variety of materials including carbon steel, stainless steel, aluminum, and copper. This enables us to create the outer jackets, structural frames, and mounting systems necessary to encapsulate and support heavy radiation shielding.
Product Development and DFM
We partner with clients during the early stages of product development to provide design for manufacturing (DFM) expertise. By analyzing shielding requirements and mechanical constraints, we help optimize designs for cost-effective production without compromising safety or performance. Our team bridges the gap between complex radiation physics and practical manufacturing, ensuring that your industrial radiation shielding projects move from concept to completion with maximum efficiency.
