Gamma Ray
Alpha radiation is the least penetrating type of radiation. It consists of helium nuclei and has low penetration power, being stopped by skin or even a sheet of paper.
Alpha radiation.
Alpha radiation is the least ionizing type of nuclear radiation. It consists of positively charged alpha particles, which have low penetrating power and are easily stopped by a sheet of paper or clothing.
Gamma radiation is the most penetrating type of radiation in solid substances due to its highly energetic nature and ability to penetrate through thick materials. Its high penetration power makes it difficult to shield against, requiring dense materials such as lead or concrete for effective protection.
Penetration power of electrons means the power of orbitals to attract electrons. More the penetration power of electrons , More will be the ionization Enthalpy (Amount of energy required to remove one electron)
The gamma radiation is extremely penetrant.
Gamma radiation
Polonium-210 primarily emits alpha radiation, which consists of two protons and two neutrons. This type of radiation has a low penetrating power and is highly ionizing, making it hazardous if ingested or inhaled.
Gamma radiation typically requires thick radiation shielding, such as lead or concrete, due to its high penetrating power. This type of radiation can pass through barriers like paper, skin, and clothing, making it necessary to use heavier materials to provide effective protection.
Alpha particles are composed of two protons and two neutrons and have low penetrating power; beta particles are high-speed electrons or positrons with moderate penetrating power; gamma rays are high-energy electromagnetic radiation with high penetrating power; neutron emission involves the release of neutrons with no charge and high penetrating power. Each type of radiation causes different ionization effects in matter and poses different risks to human health.
the neutrino
Gamma radiation is considered the most deadly type of radiation as it is highly penetrating and can easily damage tissues and cells in the body. This type of radiation is emitted during nuclear reactions and explosions.
