linear attenuation coefficient

The linear attenuation coefficient is a measure of how much a material weakens or reduces a specific type of energy, like X-rays or gamma rays, as it passes through. It tells us how easily the radiation is absorbed or scattered by the material. A higher coefficient means the material is more effective at blocking or diminishing the energy, while a lower coefficient indicates it allows more energy to pass through. This concept is important in medical imaging, radiation shielding, and other fields where controlling radiation's movement is essential.
