Vacuum Packing High Contrast X-Ray Flaw Detector , Type D7 Industry Radiographic
Film
General Characteristics:
Type D7 industry radiographic film is a fine grain, high contrast,
high radiation sensitive, high definition radiographic film made by
using novel emulation technology. Designed for direct exposure or
with lead screens. For exposure with lead screens using either
X-ray or gamma rays.
The D7 radiographic film consider two fundamental factors of the nondestructive control
(NC) - quality of the image and stability of properties.
Applications :
This film is suitable for different NDT applications such as:
medium thickness heavy metals and alloys, fairly thick light metals
and alloys, and also suitable for NDT of heavy metal parts having
thick section when exposed with high-energy radiation. The film is
especially suited to high temperature automatic processing. This
product is compatible with international norms.
