Radiation Absorption Coefficient
The radiation absorption rate indicates how strongly a material absorbs gamma or X-rays. The higher the value, the more radiation is absorbed and the less passes through the material.
Physico-chemical mechanism of action
The radiation absorption coefficient (RAC) of a material is a measure of the probability that a radiation particle is absorbed when passing through the material. This process depends on the type of material and its thickness. Metals with many free electrons, such as lead or titanium, have a high RAC and are therefore well suited as radiation protection.
Metallurgical relevance & risks in welding
A high radiation absorption coefficient can lead to safety issues in the workshop. For example, gamma rays released during welding of certain materials (such as titanium or lead) can be dangerous and expose personnel. It is therefore important to take appropriate protective measures to minimize radiation exposure.
Workshop practice & instructions
To ensure that the radiation absorption coefficient in the workshop remains under control, the following measures should be taken:
• Wear protective clothing and a safety helmet with integrated X-ray shielding.
• Always keep at least 1 meters away from the work area when working with highly radiating materials.
• Make sure all radiation sources are properly shielded and regularly checked.
