NM01LFNUM1/4M

This package contains 100 individual lead number figures, each precisely manufactured with a height of approximately 1/4 inch (7 mm), a width of approximately 4 mm, and a thickness of 1.5 mm. These radiopaque numbers feature a flat face for clear imaging and are securely mounted on a thin, transparent plastic base for ease of handling and accurate placement during industrial radiography procedures. They serve as essential identification markers, creating clear and permanent notations on radiographic film.  

Key Features:

• Radiopaque Lead Construction: Fabricated from lead, a material highly effective at attenuating X-rays and gamma rays, ensuring distinct and legible markings on radiographs.

• Standard Dimensions: Each number conforms to a standardized size of approximately 1/4 inch (7 mm) in height, 4 mm in width, and 1.5 mm in thickness, a common specification for industrial radiography identification markers.  

• Assorted Number Set: The package includes 100 individual number figures (typically 0 through 9, repeated multiple times). The exact assortment may vary slightly depending on the supplier.  

• Convenient Plastic Base Mounting: Each lead number is affixed to a thin, clear plastic base. This mounting provides several advantages, including simplified handling, precise positioning on the item under inspection, and prevention of direct lead contact with the test surface.  

• Bulk Packaging: Supplied in a package containing 100 individual lead number figures, suitable for high-volume radiographic operations.  

• Permanent Radiographic Identification: Designed to produce sharp, high-contrast number markings on developed radiographic film, providing a permanent means of identifying specific areas, views, or components within the inspection.

• Flat Face Design: The flat face of the lead numbers ensures clear and easily readable digits on the resulting radiograph.  

Applications:

• Industrial Radiography (Non-Destructive Testing): Primarily used in non-destructive testing to clearly identify specific regions of interest on components being examined using X-rays or gamma rays, such as welds, castings, and structural elements.

• Radiographic Film Annotation: Placed directly on the object before exposure, the lead numbers create opaque images on the processed film, serving as permanent annotations.

• Inspection Traceability: Crucial for maintaining accurate records and facilitating the tracking of radiographic inspections by clearly labeling different exposures or sections of a test item.

• Quality Assurance Procedures: An integral part of quality control processes in manufacturing and fabrication industries that rely on radiographic inspection for defect detection and material integrity verification.

Importance:

• Ensures Clear and Unambiguous Identification: Provides a reliable method for creating easily readable identification marks on radiographic images.

• Establishes a Permanent Record: The lead markings become a permanent feature of the radiograph, ensuring long-term referenceability and traceability.

• Aids in Accurate Interpretation: Assists radiographers and inspection personnel in correctly interpreting and referencing specific locations or features within the radiographic image.

• Supports Regulatory Compliance: Often mandated by industry-specific standards and regulatory requirements for thorough and auditable radiographic examinations.
