Radiography In Modern Industry
INTRODUCTION
Many of the outstanding scientific and engineering breakthroughs of the last several years may be traced back to nondestructive testing procedures, which, by assessing internal soundness without compromising product usefulness, ensure that the product performs as intended.
Radiography is one of the most essential and adaptable nondestructive testing methods utilised in modern industry. Radiography, which uses highly penetrating x-rays, gamma rays, and other forms of radiation that do not damage the part itself, creates a permanent visible film record of internal conditions that contains the basic information needed to establish soundness.
In the last decade alone, evidence from millions of film records, or radiographs, has enabled industry to ensure product reliability, offered informational ways of averting accidents and saving lives, and benefited the user.
Because economic justification is an important criterion for every testing procedure, radiography’s worth is somewhat dependent on its ability to generate a profit for its user. This value is evident in machining operations, where only items known to be in good condition are permitted on the manufacturing lines.
It is also seen in cost savings when less expensive materials or fabrication methods can be used instead of more expensive ones, if soundness is simply an anticipated quality. The information obtained by radiography also helps the engineer create better items and protects the corporation by ensuring a consistent, high level of quality in its products.
Overall, these advantages can serve to increase customer satisfaction and promote the manufacturer’s reputation for excellence. Industrial radiography is quite versatile.
Radiographed objects span in size from tiny microscopic electronic elements to mammoth missile components; in product composition from nearly every known material; and in produced form from a vast variety of castings, weldments, and assemblies.
Radiographic inspection has been used on organic and inorganic materials, solids, liquids, and even gases. An industry’s radiograph production can range from the occasional inspection of one or two pieces to the examination of hundreds of specimens each hour.
Because of the vast range of applications, independent, professional x-ray laboratories have emerged, as have radiographic divisions inside industrial companies. Industry’s radiographic inspections are frequently monitored for quality by its customers — other manufacturers or governmental agencies — who use applicable specifications or codes mutually agreed upon by contract and provided by several technical societies or other regulatory groups.
To meet industry’s growing and changing demands, radiography research and development are constantly producing new sources of radiation such as neutron generators and radioactive isotopes; lighter, more powerful, and more portable x-ray equipment
as well as multi-million-volt x-ray machines designed to produce highly penetrating radiation; new and improved x-ray films and automatic film processors; and improved or specialised radiographic techniques. These elements, combined with the efforts of many dedicated individuals, increase radiography’s utility in industry.
It is not surprising, then, that radiography, the first of the contemporary advanced methods of nondestructive testing (developed in 1895), has caused hundreds of businesses to place enormous trust in the information it provides.
The list grows year after year as industry managers, designers, engineers, production workers, inspectors, and anybody else interested with good procedures, dependable products, high yields, and fair profits realise the importance of radiography in modern industry.
