For IR, visible, and UV radiation; any shiny surface will do. For acoustic radiation, any massive smooth surface will do. For em radiation, any material with a very different dielectric constant from that of air will do. For ionizing radiation, there is a lot of money to be made from this discovery. That problem is yet (mainly) to be solved.

Why is much of the sun's radiation reflected back in to space by earth?
Such reflection is called the albedo. For the earth it is 30 - 35%
How is gamma radiation used in medicine?
gamma radiation is used in cancer treatment. the most common source of gamma radiation is.
What does the skin pattern of a garter snake reflect?
the pattern most likely reflect differences in the snakes' habitat.
Is sunlight just like radiation?
Yes sunlight is composed of ultraviolet rays which are electromagnetic radiation
Does a pet scan use radiation?
Doesn't it make you wonder why these radiation questions have not been answered??
What sort of radiation absorbs or reflect radiation?
It doesn't absorb clever. It penetrates, and it can penetrate paper, smoke, a layer of skin and thin aluminium.
How is the sun reflecting it radiation into space?
The sun does not reflect its radiation into space.
Do mirrors reflect without light?
Mirrors reflect whether there is anything to reflect at the minute. Beside light they can also reflect heat radiation.
How might a thick puffy cloud reflect a different amount of the Sun's radiation than a thin wispy one?
Thick puffy cloud reflects suns radiation thick clouds reflect radiation keeping earth cool. Thin wispy cloud reflects sun radiation thin don't reflect as much radiation allowing the earth to warm.
Do clouds reflect sun's radiation?
Some of it but not all. They can also retain some types of radiation, especially thermal radiation.
What the fraction of radiation a surface can reflect is called?
Reflection
What color light does a yellow shirt reflect?
It reflects a radiation of b radiation which is a color green.
Does white plastic absorb or transmit solar radiation?
White anything will REFLECT radiation, it will not transmit or absorb.
How does volcanic ash in earths atmosphere effect solar radiation?
It increases the amount of solar radiation that reflect into space
How might a thick puffy cloud reflect a different amount of the suns radiation than a thin wispy one?
Thick puffy cloud reflects suns radiation thick clouds reflect radiation keeping earth cool. Thin wispy cloud reflects sun radiation thin don't reflect as much radiation allowing the earth to warm.
Which object or material reflects infrared rays?
All materials will reflect, absorb and transmit (allow to pass through) electromagnetic radiation. This is called the Transmit/Reflect (T/R) ratio and it will vary for a material based on the wavelength of the incident radiation. IR radiation does not transmit through most materials. It is absorbed/reflected. Metalized Mylar has a small transmit/reflect ratio.
How do clouds reflect heat to earth?
Cloud cover prevents IR radiation and light from escaping to space, preventing cooling by radiation.
