What kind of energy can travel through radiation?
Radiation carries electromagnetic energy, such as visible light, infrared radiation, ultraviolet radiation, and radio waves. It can also carry particles, such as alpha and beta particles, along with energy.
What kind of radiation does Rn-222 emit?
Rn-222 emits alpha radiation. This type of radiation consists of alpha particles, which are made up of two protons and two neutrons. Alpha radiation tends to have low penetrating power and can be stopped by a piece of paper or human skin.
Why are alpha and beta rays deflected in opposite directions in a magnetic field?
An alpha particle, which is a 24He nucleus, has a mass of 4 and a charge of +2. A beta particle has a charge of +1 or -1, depending on whether it is a positron (beta +) or an electron (beta -). It's mass is minuscule compared to the alpha particle, and it will undergo a comparatively huge deflection in the same field as an alpha particle would. Though the alpha particle has twice the charge as a beta particle, it has several thousand times the mass of that beta particle. As it is so much more massive than the beta particle, its inertia will be much more difficult to overcome even though it has twice the charge.
What kind of material should you NOT use to shield against beta radiation?
Materials that should not be used to shield against beta radiation include materials with low atomic numbers, such as plastic or wood, as they are not dense enough to effectively stop beta particles. Materials with higher atomic numbers, such as lead or dense metals, are more effective for shielding against beta radiation.
What part of the atom does nuclear radiation come from?
Nuclear radiation comes from the nucleus of an atom. It can be emitted in the form of alpha particles (helium nuclei), beta particles (high-energy electrons), or gamma rays (high-energy electromagnetic radiation).
What kind of energy can travel through radiation?
Radiation carries electromagnetic energy, such as visible light, infrared radiation, ultraviolet radiation, and radio waves. It can also carry particles, such as alpha and beta particles, along with energy.
What kind of particle is emitted?
Particles emitted can be in the form of alpha particles, beta particles, or gamma rays. Alpha particles consist of two protons and two neutrons, beta particles are electrons or positrons, and gamma rays are high-energy electromagnetic radiation.
One kind of radiation not released by radioactive decay is .?
alpha particles
What kind of radiation is emitted from protactinium?
Protactinium-231 emit alpha particles, gamma radiations, X-rays.
What happens to the motion of molecules when they are heated?
What kind of radiation? Remember, Beta radiation is particles (electrons)and Alpha radiation is Helium nuclei.Some radiation will transfer energy to particles ... which may speed them up,it may heat them,it may cause fluorescence.
What kind of rays does uranium 235 and plutonium 239 release?
Uranium-235 and plutonium-239 release alpha, beta, and gamma rays during the process of radioactive decay. Alpha particles are helium nuclei, beta particles are high-energy electrons or positrons, and gamma rays are electromagnetic radiation.
What type of radiation is only a hazard when inhaled or ingested?
Although there are many forms of "radiation" when assessing radiation hazards we usually think in terms of just three forms of radiation: alpha, beta, and gamma. Of these, alpha radiation is only a hazard if a source is inhaled or ingested - the other two are a hazard even without inhalation or ingestion. In general, external alpha radiation is not harmful since alpha particles are effectively shielded by a few centimeters of air, a piece of paper, or the thin layer of dead skin cells. On the other hand, if you inhale or ingest an alpha emitter, it can cause significant damage if the radiation is intense enough. Beta particles (electrons) are more penetrating, but still can be absorbed by a few millimeters of aluminum. Whatever harm beta radiation can cause, it doesn't have to be inhaled or ingested to do it. Gamma radiation is the most penetrating - that's the kind of radiation we usually think of using lead to shield us from. Again, gamma radiation is a hazard whether or not you inhale or ingest it.
How is the atomic number changed by gamma decay?
There is no change in atomic number with the emission of gamma radiation. Unlike alpha or beta radiation, it does not have any kind of particles. It's emission results only when an excited nuclei goes to an unexcited state by emitting these.
What kind of particles are equivalent to helium nuclei and are the most ionizing form of nuclear radiation?
An alpha particle
What kind of radiation does Rn-222 emit?
Rn-222 emits alpha radiation. This type of radiation consists of alpha particles, which are made up of two protons and two neutrons. Alpha radiation tends to have low penetrating power and can be stopped by a piece of paper or human skin.
What kind of energy does a piece of radioactive metal use?
Nuclear energy. This is basically a form of kinetic energy. The structure of a radioactive material is very unstable, and as a result, they, at random, kick of particles or waves in the form of either Alpha, Beta or Gamma radiation. Alpha waves are Helium nuclei, and as a result are waaaay to big to be of any real harm. Beta particles are essentially electrons, and as such are a bit more tricky. They tend to get in places you don't want them to get. Gamma radiation is by far the most dangerous, as it is a wave and can penetrate several feet of metal. It is this energy that we harness and use to create fuel, or at least that is how I understand it.
Why are alpha and beta rays deflected in opposite directions in a magnetic field?
An alpha particle, which is a 24He nucleus, has a mass of 4 and a charge of +2. A beta particle has a charge of +1 or -1, depending on whether it is a positron (beta +) or an electron (beta -). It's mass is minuscule compared to the alpha particle, and it will undergo a comparatively huge deflection in the same field as an alpha particle would. Though the alpha particle has twice the charge as a beta particle, it has several thousand times the mass of that beta particle. As it is so much more massive than the beta particle, its inertia will be much more difficult to overcome even though it has twice the charge.
