Gamma ray source
An isotope source is a radioactive source that emits high-energy gamma radiation. It is used for material testing to radiograph thick-walled welds in a mobile manner without electrical power.
Physical-Chemical Mechanism of Action
An isotope source generates high-energy gamma radiation through the radioactive decay of isotopes such as cobalt-60. This radiation has high penetration and can penetrate thick materials without a power supply.
Metallurgical Relevance & Risks in Welding
Gamma radiation can be used to inspect the density and structure of materials. Improper handling or excessive exposure can be dangerous and damage human tissue. Therefore, safety measures like protective clothing and dose limits are essential.
Workshop Practice & Instructions
Use the isotope source in a protected environment with appropriate safety measures. Ensure the source is not active longer than necessary and carry out regular dose checks. Wear proper protective clothing and equipment to minimize radiation risk.
