First of all, they are not referred to as "gamma particles." The proper term is "gamma ray" or "gamma radiation."
a thick sheet/ block of lead
a few centimetres of aluminum or 20-30 centimentres of air.
Aluminium Foil
The range of beta particles in the air is up to several hundred feet. Beta particles are emitted by specific types of radioactive nuclei. Potassium-40 is a type of radioactive nuclei that emits beta particles.
What is the range of beta particles in air as compare to alpha particles?Read more: What_is_the_range_of_beta_particles_in_air_as_compare_to_alpha_particles
Alpha particles are positively charged helium nuclei while beta particle are negatively charged electrons . Alpha particle have 4u mass while beta particles have zero mass.
it is electrons
A beta particle has an electric charge of -1 because beta particles are both lightweight and fast moving, they have a greater penetrating power than alpha particles.
Beta particles, from beta- decay, have a charge of -1. Beta particles, from beta+ decay, have a charge of +1. Alpha particles have a charge of +2.
Beta particles are not stopped by a paper sheet.
Low energy beta particles, say, from tritium, are called soft beta particles.
alpha particles=8 and beta particles=6
Beta Particles have a negative charge,In Beta decay a neutron changes into a proton and a beta particle, an electron.
Thin sheet or plastic may prevent beta particles.
Beta particles are often used in smoke detectors.
The range of beta particles in the air is up to several hundred feet. Beta particles are emitted by specific types of radioactive nuclei. Potassium-40 is a type of radioactive nuclei that emits beta particles.
Both Beta and alpha particles can be blocked by a block of lead. Alpha particles can even be blocked by a sheet of paper, and beta particles can be blocked by a thin aluminium plate.
The minimum protection against exposure to beta particles is a thin sheet of metal or plastic. Beta particles are classified as subatomic particles.
