Gamma rays have no mass & therefore deposit less energy per unit of length (low LET or linear energy transfer). Alpha particles on the other hand have a relatively large mass and deposit much energy in a very small unit of length. Because of this, alpha particles will not go very far in air and can be shielded by a piece of paper. Gamma rays however, travel several meters and can even penetrate walls.
What else can I help you with?
What type of radiation has the least ability to penetrate matter?
Alpha radiation has the least ability to penetrate matter. It consists of particles that are relatively large and heavy, which makes them easier to block. They can be stopped by a piece of paper or human skin.
Is cathode rays have maximum ionising power than alpha beta gamma rays?
No, alpha particles have the highest ionizing power due to their larger size and positive charge. Cathode rays have less ionizing power compared to alpha particles, but they still have the ability to ionize atoms and molecules when they interact with them.
Why is gamma radiation different from alpha and beta radiation?
Gamma radiation is a type of electromagnetic radiation, whereas alpha and beta radiation are composed of particles. Gamma rays have the shortest wavelength and highest energy, whereas alpha and beta particles are larger and less penetrating. Gamma radiation does not carry an electric charge, while alpha and beta particles do.
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.
What radiation has the weakest penetrating power?
Alpha radiation has the weakest penetrating power among the three common types of radiation (alpha, beta, gamma). Alpha particles can be stopped by a sheet of paper or a few centimeters of air, making them less penetrating but more damaging if inhaled or ingested.

Why are gamma rays less ionising?
it does not

What are beta and alpha rays?
Alpha: Highly ionising particles that can not penetrate the skin, smoke or most substances. It's only dangerous when inhaled or ingested. Beta: Is slightly less ionising but can penetrate air, layers of skin and paper. It's only slightly more dangerous than Alpha.

Is alpha or gamma is more absorbed by matter?
Gamma radiation is more penetrating and is able to travel further through matter compared to alpha radiation. Alpha radiation, on the other hand, is absorbed quickly by even a sheet of paper or skin due to its larger mass and charge, making it less penetrating than gamma radiation.
Health risks of the alpha beta and gamma?
Alpha and Beta radiations are not very strong and are blocked even by our clothes but gamma radiation is highly ionizing and requires protection at large. It is highly ionizing and once coming in contact with the body, it can produce cellular reactions and could cause genetic mutations. ^ sorry but thats wrong... actually gamma is less ionising than alpha and beta. just saying... -Djsaf
What are the three kinds of nuclear radiation?
The three types of nuclear radiation are alpha particles, beta particles, and gamma rays. Alpha particles are helium nuclei consisting of two protons and two neutrons, beta particles are high-speed electrons or positrons, and gamma rays are electromagnetic radiation of high energy.
Gamma radiation is it safe to inject into a human but alpha particles would be very dangerous?
Generally no radiation is safe. You cannot "inject" radiation into anything because it is the product of various unstable nuclei decaying. Alpha radiation is much more ionising than gamma, but much less penetrating than it. That makes it more dangerous if it is inside your body; it can be stopped by skin. Therefore you would have to swallow a sample of a radioactive material. However, gamma radiation is always emitted together with alpha or beta radiation.
Which statement best describes the effect of betta particles on body tissue?
They cause more damage than the alpha partials but less than gamma rays
Will clothing and skin block the majority of the alpha and beta particles from DU materials?
These things might block the majority of alpha and beta particles as they are not very much penetrating but the gamma radiations won't be blocked by these. To block gamma radiations, we need things like lead walls because gamma particles' are extremely penetrating.
