What materials can block electromagnetic radiation?
That depends on the wavelength of the radiation.chicken wire can block radiation with a wavelength longer than about 10cm.a metal screen with 2mm holes can block radiation up to microwaves.most solids can block IR and visible light.lead is typically needed to block x-rays.many meters of lead and/or concrete is needed to block gamma rays.
Does sunblock help against nuclear radiation?
Sunblock is made to block Ultraviolet radiation. Nuclear radiation, or Gamma radiation, is much more energetic and will easily penetrate zinc oxide sunblock, walls, and most everything else except several feet of concrete or a few inches of lead. In addition to Gamma radiation, nuclear reactions also give off less energetic particles called Alpha and Beta particles which can be inhaled and cause damage, which is why the Japanese are wearing wet wipes inside their face masks.

What are substances that block radiation?
You mean a physical substance which could be lead or concrete. Some ultraviolet radiation can be blocked by sunblocks and clothing. Other types of radiation such as X-Rays used in medicine can be blocked by lead.
What is heavier a concrete block or a brick?
Concrete block.
What are the dimensions of a concrete block?
Basic concrete block it 8x8x16 inches.
How many concrete block to a m2?
There are 10 concrete block per m2.
What is the strongest home design material. Concrete block or wood frame?
concrete block
What does an 8 x 10 x 16 concrete block weigh Is there a difference between a concrete block a concrete cinder block?
It weighs 59 lbs. There is a difference between a "real" cinder block and a concrete block. A cinder block uses cinders--ash from the burning of coal--as its aggregate. Concrete blocks are made from concrete. Concrete block is far stronger than is cinder block, and some jurisdictions prohibit the use of cinder block. The only justification for cinder block is that it weighs less than concrete block, which is important if the ground you're building on isn't strong enough to support a heavy structure. This justification has gone away, because now you can buy concrete block made from expanded-shale aggregate that's as light as cinder block and as strong as standard-weight concrete masonry.
What is the difference between a concrete block and a brick block?
A concrete block is made from concrete, a brick block is made from brick. They are two different building materials. Both have their respective advantages and disadvantages.
What are some examples of materials that reduce radiation?
Radiation will occur, we cant really decrease this - aside from diluting the source. We can put up barriers to block the radiation however. There are three main radiation types of radiation, with varying amounts of penetrative power; Alpha radiation - which can be stopped with paper or a few cm of air. Beta radiation - which can effectively be blocked with thin aluminum sheet Gamma radiation - Which has the most penetrating power, and will take several mm of lead or several feet of concrete to effectively block.
What products can you use little of and still block radiation?
It depends on what kind of radiation... Alpha radiation can be stopped with a sheet of paper or a few inches of air. Beta radiation can be stopped with a thin sheet of metal. Neutron radiation, depending on energy, requires large thicknesses of lead or concrete. Gamma radiation, depending on energy, also requires large thicknesses of lead or concrete. Some of the higher energy gammas, such as cosmic rays, can be quite difficult to stop at all.
