Does aluminum foil block nuclear radiation?

To make your bedroom as resistant to nuclear energy as possible, start by insulating your windows and doors with aluminum foil. Bricks and mattresses can also provide additional protection against heat and radiation. Beta particles can only travel a few meters, but they can penetrate paper or skin. However, a thin sheet of aluminum or lead, a piece of glass or plexiglass, or a block of wood can block these particles.

The aluminum foil should be only 3 to 4 millimeters, and the lead should be about 3 centimeters thick to stop beta particles, but it depends on the radiation dose. Some particles will dissipate in the air. Beta particles are emitted during natural processes, but they are also used in some medical treatments, such as eye diseases. Aluminum can stop all types of radiation from nuclear decay if it is thick enough.

One of the best ways to be prepared is to understand the principles of radiation protection of time, distance and shielding. During a radiological emergency (a large release of radioactive material into the environment), we can use these principles to help protect ourselves and our families. In a large-scale radiological release, such as an accident at a nuclear power plant or a terrorist incident, the following tips have been proven and proven to provide maximum protection. A few centimeters of lead is enough to block gamma rays, so a lead apron is used when doing an X-ray, but at least 3 meters of concrete are needed to stop them.
