This document discusses three non-destructive testing methods: radiography, which uses gamma rays to examine the inside of objects; gauging, which determines thickness by passing radiation through an object; and neutron activation analysis, which determines the quantity of elements in an object using radioisotopes. It provides examples of how each method can be used and concludes that using gamma rays for non-destructive testing can save time, money, and lives by identifying issues without taking apart machinery.

- 2. Radiography Gauging Neutron Activation
- 3. Use of gamma rays to examine the inside of an object without taking such object apart. Gamma rays can help you find cracks, missing pieces, and other problems with machinery.
- 4. Gauging- Determines thickness by passing radiation through the object. Determines if enough of a material was used to make object. Example: Steel is strong enough to support a bridge.
- 5. Neutron Activation- Determines quantity of element in an object with the use of radioisotopes. Determines quality of elements. Example: Examining a pipe to determine which metals and how much of each metal were used to make the pipe. Allows an evaluation of the strength and durability of object.
- 6. Using gamma rays can save time, money, and lives. Time- It takes less time because pipes are not taken apart piece by piece. Money- Less labor is required. Lives- Keeps machines operating properly keeping consumers and workers safe.
