Darker surfaces are generally better at absorbing radiation compared to lighter surfaces. Surfaces that are rough or have more surface area also tend to be better at absorbing radiation. Additionally, surfaces that are flat and perpendicular to the radiation source will typically absorb more radiation.
Silver can act as a barrier to radiation by reflecting and absorbing the radiation energy. When applied as a coating, it can reduce the transmission of radiation through the material it covers, thereby acting as a shield against certain types of radiation.

A Geiger-Muller counter would be a suitable instrument for general radiation work and detecting contaminated surfaces. It provides a simple and effective way to measure radiation levels without distinguishing between different types and energies of radiation.
Surfaces that are hard and smooth, such as glass, tile, concrete, and metal, typically cause reverberation by reflecting sound waves. Conversely, softer and absorbent surfaces like curtains, carpets, and acoustic panels tend to reduce reverberation by absorbing sound energy.
Surfaces that are dark in color, rough, and have a low albedo (reflectivity) tend to absorb more heat. Common examples include asphalt, concrete, and dark-colored metals like iron. These surfaces absorb solar radiation and convert it into heat energy.

The two most important types of surfaces on Earth for absorbing solar energy and maintaining warmth are oceans and forests. Oceans cover about 71% of the Earth's surface and absorb a significant amount of solar radiation, helping to regulate global temperatures. Forests, particularly tropical rainforests, also play a critical role by absorbing sunlight and storing carbon, which contributes to the greenhouse effect and helps retain heat in the atmosphere. Together, these surfaces are vital for the planet's climate system.

Surfaces with the highest albedo include ice and snow, which reflect a significant amount of incoming solar radiation due to their light color and texture. Other high-albedo surfaces include deserts with light-colored sands and certain types of clouds. In contrast, darker surfaces like forests or oceans have lower albedo, absorbing more sunlight. Overall, materials with lighter colors and reflective properties contribute to a higher albedo.

Surfaces with high albedo reflect a significant percentage of incoming solar radiation. Examples include ice and snow, which can reflect up to 90% of sunlight, as well as light-colored deserts and certain types of clouds. Urban areas with reflective materials, such as white or light-colored rooftops, also exhibit high albedo. In contrast, darker surfaces like forests and oceans have low albedo, absorbing more sunlight.
The two types of surfaces on Earth that are most important for absorbing solar energy and keeping the planet warm are land and water. Land surfaces absorb and release heat quickly, while water surfaces have a higher heat capacity and can store more heat, regulating temperatures and influencing weather patterns.

Types of light energy are reflected off of shiny surfaces back into the atmosphere. Other surfaces, such as darker ones, absorb the light energy and heat up much quicker.
