METTLER-TOLEDO INTERNATIONAL INC.
Mettler-Toledo International Inc. was established in 1989 in Columbus, US. This multinational is a global manufacturer of exactitude instruments that are used in industrial and food retailing applications and laboratories. It provides product inspection, laboratory analytical solutions, industrial weighing, process analytics, etc., and it is especially known as one of the first companies to use industrial radiography for inspections.

■ Industrial radiography
Industrial radiography is a method used to test materials for flaws, such as cracks. Using high-energy electromagnetic radiation (x-rays, gamma rays, or ultrasounds), testers can see a material’s internal structure and look for problems without damaging the materials; industrial radiography is a non-destructive way to test products such as pipes, welded materials, or airplane parts. These testing procedures ensure that the materials are safe and of good quality.

■ Inspections and safety equipment
Industrial radiographers are required by governing authorities to use certain types of safety equipment and to work in pairs. Depending on location, the radiographers may have been required to obtain permits, licenses and/or undertake special training.
Before conducting any testing, the nearby area must always first be cleared of all other persons and measures should be taken to ensure that workers do not accidentally enter an area that may expose them to dangerous levels of radiation. Their safety equipment usually includes four basic items: a radiation survey meter (such as a Geiger counter), an alarming dosimeter or rate meter, a gas-charged dosimeter, and a thermoluminescent dosimeter (TLD).
