What is unknown radioactive elements?
A radioactive element is the element which radiates continuously giving alpha, beta, and gamma rays. The elements having atomic no. more than 82 are mostly considered as radioactive elements. These elements emit radiations by themselves even if if they are not get touched. They are discovered by Maria Curie and Pierre Curie in 1907
What particles give off high energy?
Radionuclide or radioisotope is a substance that give off high energy particles or rays as it disintegrates. They emit three types of radioactivity is alpha particles, beta particles, and gamma rays.
What are positively charged radioactive rays called?
alpha particles
One kind of radiation not released by radioactive decay is .?
alpha particles
Which radioactive particle can be stopped by a regular sheet of notebook paper?
Alpha. Beta particles are blocked by a few mm of aluminum and gamma by a few cm of lead. Alpha. Beta particles are blocked by a few mm of aluminum and gamma by a few cm of lead.
What type of particles are emmitted by radioactive elements?
Gama radiation.Beta particles (electrons or positrons)Alpha particles (helium nuclei)Neutrons and sometimes Protons.
What do you understand by the term radioactive?
It refers to elements that undergo nuclear fission and, in the process, emit atomic particles (alpha and beta particles) and energy (gamma rays).
What is a beta emitter?
In physics, an alpha emitter is a radioactive substance which decays by emitting alpha particles.
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.''
Why are radioactive elements which emit alpha particles more dangerous outside the body than inside?
It is the opposite. Radioactive elements which emit alpha particles are more dangerous inside the body than outside. Alpha particle radiation could be stopped by skin. So, is not dangerous outside the body. However, any contamination by those radioactive elements if got inside through mouth, or any other means, then the alpha particle radiation could be harmful to the very delicate inside body tissues.

What are the alpha particles in the environment?
Naturally occurring alpha particles are mostly from cosmic radiation and radioactive isotopes such as Americium and Uranium.
What radioactive emission is that most easily absorbed?
Alpha particles.
How is californium radioactive?
Californium emit alpha particles and neutrons.
What radioactive emanations have a charge 2 plus?
Alpha Particles
What are positively charged radioactive rays called?
alpha particles
