Concrete is a common material used to shield against radiation. The amount of concrete needed to effectively stop radiation depends on the type and intensity of the radiation. Thicker layers of concrete provide better protection against radiation. Generally, a thickness of at least several feet of concrete is needed to effectively stop most types of radiation.
Materials such as lead, concrete, steel, and water can be used to block radiation or radioactivity. The effectiveness of the material in blocking radiation depends on factors like the type of radiation, energy level, and thickness of the material. Lead is commonly used due to its high density and ability to absorb gamma radiation effectively.
Foam used for radiation shielding acts as a physical barrier, absorbing and attenuating radiation as it passes through the material. Foam can trap radioactive particles and prevent them from spreading. Additionally, some foams contain materials that actively absorb or scatter radiation, contributing to the overall effectiveness of the shielding.
Lead is commonly used to shield against radiation because it is dense and effective at absorbing radiation. To effectively stop radiation, lead typically needs to be at least 1 inch thick.
Radiation absorbed dose (rad) is a unit used to quantify the amount of energy absorbed from ionizing radiation by a material or tissue. It is defined as the energy deposited by ionizing radiation per unit mass of the absorbing material.
The radiation comes from the material used.
Materials such as lead, concrete, and water are commonly used to block or absorb radiation and protect against its harmful effects. Lead aprons are frequently used in medical settings to shield patients from radiation during x-ray procedures.

The material that is most usually used to stop radiation is lead. Lead is composed of large atoms, being a heavy element with a high atomic number, and it is therefore quite opaque to radiation of all sorts. There are many other heavy elements which can stop radiation, however, lead is the most easily available. You can use platinum as well, but it is thousands of times more expensive than lead.

If by ionising radiation you mean alpha radiation (the most ionising out of alpha, beta and gamma radiation) then about a millimetre of paper would stop it. alpha radiation ionises the molecules of anything it reaches, but can pass through very few things due to its immense ionising power. This includes human tissue, but in all honesty, a large dose of alpha radiation wouldn't do human tissue alot of good. In short, almost any material can stop ionising radiation.
There are three primary types of nuclear radiation. Bricks will block both alpha particles and the more deeply penetrating beta particles. To stop gamma radiation, you would need several feet of brick. Lead is considered a better material for blocking high energy gamma rays.
