Can concrete block radiation?
Some beta particles can penetrate and burn the skin. γ GAMMA: To reduce typical gamma rays by a factor of a billion, thicknesses of shield need to be about 13.8 feet of water, about 6.6 feet of concrete, or about 1.3 feet of lead. Thick, dense shielding is necessary to protect against gamma rays.
It cannot go around corners, and it can't even reflect off of surfaces. As long you are not in the line of sight from a radiative source, you will not experience any radiation. While it will reduce the inhalation of radioactive airborne particles, it will not stop the radiation from those particles.
- When we say sheltered, we mean “underground”. At least 3 feet of soil rests above the shelter, shielding the occupants from radioactive fallout. The underground bomb shelter should be constructed in such a way as to provide maximum protection from a nuclear attack.
- Radiation cannot be spread from person to person. Small quantities of radioactive materials occur naturally in the air, drinking water, food and our own bodies. People also can come into contact with radiation through medical procedures, such as X-rays and some cancer treatments.
- Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. We call this the "speed of light"; nothing can move faster than the speed of light.
