To calculate sensitivity for a DWDI (Double Wall Double Image) technique, the job thickness you should consider is option 3:(5.54+1.5)X2

This is because in DWDI, the X-ray beam passes through two walls (each with its own thickness, including weld reinforcement), so the effective thickness for sensitivity calculation is the sum of both…

Reply to Safe Working Distance for Radiography

To calculate the safe working distance from a radiographic source, you’re correct that the inverse square law is the starting point, as it describes how radiation intensity decreases with the square of the distance from the source. However, there are additional factors to consider, such as the use of collimators and the specifics of the…

Reply to Advantages of radiography testing

Radiography testing has benefits such as the fact that it is possible to inspect the inside of an object without compromising the object’s integrity. It offers extremely clear images thus facilitating the identification of some defects such as cracks, voids, and inclusions. This method is suitable for many types of material and thicknesses and…

Reply to What is radiographic NDT?

Radiographic Non Destructive Testing is a method of examining the internal surface of a material or a component without causing any harm to it. This method uses ionizing radiation like X-rays or gamma rays to pass through the material and record an image on a radiographic film or digital detector. This way, the inspectors can recognize…

Did you know?

X-rays were discovered by the German physicist Wilhelm Röntgen in 1895. Röntgen was working on experiments with cathode ray tubes, which produce a beam of electrons, when he noticed that a fluorescent screen in his laboratory began to glow whenever the cathode ray tube was turned on. This puzzled him, as the screen was several…

Did you know:

X-ray films are made of a light-sensitive emulsion that is coated onto a transparent plastic or glass base. The emulsion contains a mixture of silver halide crystals, which are sensitive to X-rays, and other chemicals that are used to process the film and develop the image.

When exposed to X-rays, the silver halide crystals in…

Industrial radiography is a type of nondestructive testing (NDT) method that uses ionizing radiation to detect and evaluate defects in materials. The test is performed by exposing the material to a beam of ionizing radiation, such as X-rays or gamma rays, and then using specialized imaging equipment, such as film or digital detectors, to create…

Radiography source capabilities

Iridium 192, when shot with 30 curie for 45 mm thick weld joint, RT film (D7) is ok in terms of density and IQI but clarity is not there in the film.
Is it advisable to shoot such high thickness with Iridium, if so how to get good images?
