What material will stop a gamma particle?
Lead can stop gamma particles really fast because it is so dense. Gamma particles can also be reduced by water.
Is gold the best shielding against gamma radiation?
No
Which type of radiation requires thick radiation shielding?
Gamma!(:
What ype of radiation ionzing is less penetrating?
1. Alpha Particles are the least penetrating, but do a great deal of radiation damage on the surface of what they hit.2. Beta Particles penetrate to a certain extent depending on their energy.3. Gamma Rays penetrate the most, and a Gamma source requires heavy (lead, etc.) shielding.
Why the distance shielding for Gamma ray and Emitted Neturon is different?
Gamma rays are a form of electromagnetic radiation, and are absorbed by heavy materials such as lead which is often used for such shielding. Neutrons are uncharged particles which can pass through many materials, but are strongly absorbed by for example cadmium and boron, which are said to have a high capture cross section for neutrons. Therefore effective neutron shields can use such materials.
What is the radioactive emission with the greatest penetrating power?
The three types of natural radioactivity are alpha, beta and gamma radiation. Gamma rays are the most energetic, and the hardest to shield against as they do not readily interact with shielding material. Alpha and beta radiation are actually particles. The beta particle is an electron that has been released. Because of its mass, it more readily reacts with shielding material, and so cannot penetrate as far. Alpha particles are the largest and consist of two neutrons and two protons. Shielding is most effective against alpha particles. Your outer layer of dead skin or a T-shirt is generally enough to protect against alpha particles. However, this effectiveness of shielding does not mean that gamma is always the most harmful and alpha the least. The high effectiveness of shielding on alpha particles is due to the fact that they most readily react with the shield (i.e. damage it). This means that if the alpha particle is able to come in contact with living tissue (like the ingestion of radioactive liquids) it will do far more damage than a beta particle or gamma ray.

Will bricks absorb 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.
Is gold the best shielding against gamma radiation?

Is Tyvek a gamma radiation blocker?
No, Tyvek is not a good gamma ray blocker. We know that Tyvek is HDPE (high-density polyethylene), and KDPE is a hydrocarbon. Even though it is "high density" material, it is only high density compared to other poly plastics. The best gamma ray blockers are materials with high mass. Atoms with high atomic numbers and high density are the ones we need to block gamma rays. Carbon and hydrogen don't fit the bill. Tyvek is a poor choice for gamma ray shielding. What is a good choice for gamma ray shielding? We might choose lead 'cause it's cheap and easy to use as well as a good gamma blocker. Certainly concrete and dirt work fairly well as we can get a lot of that stuff together to provide gamma shielding.

What minimum type of shielding is needed to stop gamma radiation?
Gamma radiation has in principle infinite range. So it is not possible to block it completely. But it is possible to attenuate it to certain level. The thickness of concrete needed depends on gamma photons energy and concrete properties.
What safety precaution should be observed in a gamma irradiation greenhouse?
shielding and time of exposure
Which type of radioactivity would be most dangerous if you were exposed to it from a source outside of your body?
Gamma radioactivity would be the most dangerous because, unlike alpha particles that can be blocked by paper or skin, and beta particles which can be shielded by foil, gamma radioactivity would need a lead shield. Plus gamma radioactivity effects organic material.
How does the penetrating ability of gamma rays compare with that of alpha particles and beta particles?
Gamma rays are more penetrating than alpha and beta particles.
