Alpha radiation consists of heavy and highly charged particles (helium nuclei) which interact strongly with matter, losing their energy quickly. This results in a short range of penetration - typically only a few centimeters in air and stopped by a sheet of paper or human skin.

What type of radiation can only travel a short distance (a few feet) in air?
Alpha radiation is a type of radiation that can only travel a short distance (a few feet) in air. This is due to its relatively large size and positive charge, which causes it to interact strongly with atoms in the air and lose energy quickly.
Why is alpha radiation dangerous inside the body?
Alpha radiation releases a large amount of energy in a short distance, which can cause significant damage to surrounding tissues. If alpha-emitting radioactive material is ingested or inhaled, it can come into direct contact with sensitive internal tissues, leading to cell damage and potential long-term health effects such as cancer.
How far does an alpha particle travel?
This depends on their energy. An alpha particle that comes from nuclear decay is usually only able to travel a short distance, a few centimeters, through air. Alpha particles as cosmic rays, however, are much more energetic, and can penetrate quite deeply, even through many meters of solid shielding. These can penetrate the atmosphere.
Which radiation is the slowest out of alpha beta and gamma?
Alpha particles are heavy doubly ionized helium nuclei. Beta particles are nuclear electrons. Gamma are extremely short photons with zero rest mass. Hence obviously, Speed of Gamma>Beta>Alpha.
Why are radioactive elements which emit alpha particles more dangerous outside the body than inside?
Radioactive elements emitting alpha particles are more dangerous outside the body because alpha particles can travel only a short distance in air but can cause significant damage if they enter the body through inhalation or ingestion. Inside the body, alpha particles have a higher chance of being stopped by tissue before causing harm due to the limited range.

How far can alpha particles from Thorium-232 decay travel in body fluids?
Alpha particles from Thorium-232 decay have very low penetration power and can typically travel only a few centimeters in body fluids. This means that the surrounding tissues within a short distance of the particle's source would be affected by its radiation.

Does the alpha radiation souce need to have long or short half-line and why?
It depends entirely on what it is being used for.
Which radiation is the slowest out of alpha beta and gamma?
Alpha particles are heavy doubly ionized helium nuclei. Beta particles are nuclear electrons. Gamma are extremely short photons with zero rest mass. Hence obviously, Speed of Gamma>Beta>Alpha.
Why does Geiger counter not truly measure alpha radiation?
Alpha particles are Helium nuclei, two protons and two neutrons - mass 4 and charge 2. These particles have very little penetrating capability - they can be stopped with a few inches of air, a sheet of paper, your skin, etc. As a result, alpha particles have no chance of penetrating the metal shell of the Geiger counter and participating in the ionization pulses that it counts.
What types of radiations are there?
There are only two types of radiation. 1. Electromagnetic Under this we have gamma radiation, X radiation, light and heat 2. Particle radiation Under this we have alpha and beta.
Which is used for short distance travel over land and water?
Hovercraft
What happens to beta alpha and gamma radiation after they are emitted?
Beta radiation consists of high-speed electrons, which lose their energy by interacting with matter and eventually stop. Alpha radiation is composed of helium nuclei, which lose energy quickly due to their large mass and double positive charge, leading them to stop within a short distance. Gamma radiation, being a high-energy electromagnetic wave, can penetrate through matter and lose its energy through interactions such as photoelectric effect or Compton scattering.
Why are radioactive elements which emit alpha particles more dangerous outside the body than inside?
Radioactive elements emitting alpha particles are more dangerous outside the body because alpha particles can travel only a short distance in air but can cause significant damage if they enter the body through inhalation or ingestion. Inside the body, alpha particles have a higher chance of being stopped by tissue before causing harm due to the limited range.
What radiation is the most dangerous if swallowed?
Alpha radiation is the most dangerous if swallowed because it is highly ionizing and can cause significant damage to internal organs. It has a short range in tissue, making it more harmful than beta or gamma radiation if ingested.
