To what does plutonium-239 decay when it loses an alpha particle?
Yes, plutonium-239 emits alpha particles by decay.
What is Alpha radiation stopped by?
Alpha particles are the strongest of the three known types of radiation (alpha, beta, & gamma). Although the strongest, the alpha particles are the least penetrating.They do not tend to penetrate any substance.A well-known example is your skin. Alpha particles do not penetrate your skin barrier. However, alpha particles energy is high and is a cause of skin cancer and genetic mutations.
What gives off alpha particles?
Alpha particles are a type of particle of radiation that is emmited by certain radioactive materials. The materials that give off Alpha particles are called ''Alpha emitters.''
How fast do alpha particles travel?
That depends on what energy the interaction particle was at. For example if say you had a gamma at 14MeV and you got an alpha of 2MeV, now you up the energy of the gamma to 15MeV for the same reaction the alpha would have a kinetic energy (velocity) of about 3MeV. -Regards
Name the nuclear radiation that can be easily stopped by skin or cloths?
alpha particles.
What best definition radioactive decay?
The process by which the nucleus of an unstable atom loses energy by emitting radiation, including alpha particles, beta particles, gamma rays, and conversion electrons.
How would you list alpha particles beta particles and gamma rays in order of increasing energy?
Alpha, beta, gamma.
What is the effect on the mass number and change of a nucleus when it loses alpha particles?
The mass number goes down by 4, and the atomic number goes down by 2 when a nucleus loses an alpha particle. XYZ --> alpha emission --> X-2Y-4Q + 24He2+
Differentiate gamma rays from alpha particles?
Gamma rays are very high energy Photons. Whereas, alpha particles are Helium nuclei.
Do alpha particles gain energy as they ionize matter?
Yes alpha particles are matter. In fact they are just the nuclei of Helium atoms. That is Helium atoms without their two orbiting electrons. Alpha particles are therefore composed of two neutrons and two protons.
What does ionization mean?
Alpha particles have a big mass and a charge of +2. The positive charge means they cause lots of ionization in a short distance. Each time the alpha particle rips an electron off a molecule it loses some energy and slows down a bit. An alpha particle might make 100 000 ionizations before it loses all its energy. It grabs two electrons and becomes a helium atom. An alpha particle will ionize most air molecules it passes close to, which is why it loses energy so quickly and has a short range in air. This is why the cloud trails are short and fat. The alpha particle has quite a big mass. So it's difficult to change its direction. This makes the path straight.
To what does plutonium-239 decay when it loses an alpha particle?
Yes, plutonium-239 emits alpha particles by decay.
Does an alpha particle and beta particle has the same speed in a magnetic field?
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.

Why alpha particles tend to produce more ions than beta particles or gamma rays when they pass through matter?
Alpha particles have a high ionizing power beacaue they have a great linear transfer of energy.
Why does water with particles do not lose energy fast?
With clean water energy is stored but dirty water keeps energy but loses it in the end
What are types of nuclear radiation?
The most common are: gamma radiation (high energy photons), beta particles (high energy electrons or positrons) and alpha particles (high energy helium nuclei).
