SoftwareNDT Calculator – Radiographic calculator for the exposure time for iridium 192, selenium75 and cobalt 60
The Radiographic calculator programme calculates the exposure times during radiographic testing for the isotopes selenium-75, iridium192 and cobalt-60.
Exposure times in radiographic testing are crucial for the detection of material defects such as pores, lack of fusion and cracks. The exposure time depends on several factors, including the intensity of the radiation, the wavelength of the rays, the thickness of the component to be tested and the density of the X-ray film.
As the demand for more efficient and reliable testing methods continues to rise, tools like the SoftwareNDT Calculator are becoming essential in the industry. By simplifying complex calculations and providing clear visual representations of data, this software enhances the overall quality of non-destructive testing.
The film density during radiographic testing is the factor used to assess the quality of the base material and the weld seam. Differences in film density can indicate material defects, changes in material thickness or irregularities in the weld seam.
The Radiographic calculator program calculates the film density in the base material and in the weld seam.
Understanding the scientific principles behind the use of isotopes in radiographic testing can significantly enhance the effectiveness and accuracy of the testing process. For instance, Iridium-192 is commonly used in industrial applications due to its high activity level and short half-life, making it ideal for dynamic testing environments where rapid results are required.
To optimize outcomes, a detailed exposure diagram is utilised, delineating the interplay of wall thickness, activity, film and foil type, and the distance separating the film from the radiation source. This diagram showcases wall thickness in millimetres alongside activity in Ci × min. Specific exposure diagrams cater to diverse radiation sources, including X-ray tubes and elements like Cobalt 60, Iridium 192, or Selenium 75.
