Alpha particles.
Alpha radiation is the least penetrating type of radiation and is easily absorbed by a few centimeters of air, a piece of paper, or even human skin.
Radioactive isotopes that are easily absorbed by the body typically have chemical properties similar to essential elements, such as iodine or cesium. These isotopes are more easily absorbed because the body can mistake them for essential nutrients. For example, iodine-131 is readily absorbed by the thyroid gland due to its similarity to stable iodine.
Free neutrons.
No, alpha particles are not the most radioactive emission. Gamma rays are more penetrating and more energetic than alpha particles, making them the most dangerous and damaging form of radiation.
The thyroid gland is most likely harmed by exposure to radioactive iodine. Radioactive iodine can be absorbed by the thyroid gland, leading to an increased risk of developing thyroid cancer or other thyroid disorders.
Radioactive decay has nothing to do with chemistry and therefore may not be a chemical reaction. But since matter changes its properties (they are even irreversibly) it is considered to be reaction of one (elemental) reactant. Most decay reactions are kinetically of zero order.Different types of radioactive decay include decay by alpha emission (emits an alpha particle, 2 protons and 2 neutrons), Beta - emission, and Beta + emission (positron emission or electron capture).Some radioactive materials also output gamma rays, protons, neutrons, and can decay by fission.
Alpha radiation is the most easily absorbed because it consists of large, heavy alpha particles that can be stopped by a piece of paper or clothing. Beta and gamma radiation are more penetrating and can pass through thicker materials before being absorbed.
Radon is the only naturally occurring radioactive inert gas. Its most stable isotope, radon-222, decays through alpha particle emission. It is produced as a decay product of uranium and thorium in the Earth's crust.
Gamma emission is best represented by the release of high-energy electromagnetic radiation from the nucleus of an atom. This type of radiation has the shortest wavelength and highest frequency in the electromagnetic spectrum, making it the most penetrating form of radiation. Gamma emission commonly occurs during radioactive decay processes.
Radioactive emissions are particles or energy released from unstable atoms. Most humans are exposed to radioactive emissions through natural sources like the sun and radon gas, as well as medical procedures like X-rays and radiation therapy. Other sources include nuclear power plants, food, and consumer products.
No, radioactive decay is not a chemical reaction. Radioactive decay is a type of change in the nucleus of an atom that results from instability in that nucleus. And that is a nuclear reaction rather than a chemical one.
Simple carbohydrates absorb in the body more easily. They also provide the quickest source of energy to the body. Complex carbohydrates have to breakdown into simple carbohydrates before they can be absorbed by the body.
